Description

Technical Field

[0001] The invention relates to the technical field of water body monitoring and sampling, and in particular to a lake ecological environment monitoring and sampling device. Background Art

[0002] The lake ecological environment is a complex and fragile ecosystem that plays a vital role in maintaining biodiversity, water cycle and ecological balance. The health of the lake ecological environment is closely related to human life, affecting water resource utilization, ecological protection and sustainable development. With the intensification of industrialization and agricultural production activities,

[0003] The water quality of rivers and lakes is polluted by various sources including industrial wastewater discharge, pesticide and fertilizer loss, and domestic sewage discharge. Therefore, water quality testing has become a more important part of environmental protection work. In the process of water quality testing, water quality sampling and testing is required. Monitoring and sampling devices are one of the indispensable devices. Most of the monitoring and sampling devices on the market are unable to effectively collect water flows with different flow rates. For this reason, a lake ecological environment monitoring and sampling device is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a lake ecological environment monitoring sampling device.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A lake ecological environment monitoring sampling device includes an operating unit and an auxiliary unit. The auxiliary unit is vertically arranged above the operating unit. The operating unit includes four groups of arranged positioning blocks and a collecting mechanism interspersed at the interval between two adjacent groups of positioning blocks. A collecting mechanism is vertically arranged at the outer end of the collecting mechanism. The collecting mechanism includes a connecting tube and a wrapping shell sleeved on the outer ring of the connecting tube, and a guiding mechanism is arranged on the other end face of the wrapping shell.

[0006] Preferably, the guiding mechanism comprises a median tube installed at the center position of the side end face of the wrapping shell and guiding fences arranged in a circumferential manner on the outer ring of the median tube, filter fences are arranged in a ring between each group of the guiding fences, the whole device is placed vertically and slowly into the water area to be measured with the operating unit as the bottom and the auxiliary unit as the top, and the four groups of positioning blocks are vertically inserted into the silt in the water area. When the flow rate of the collected water body is large, the outer end walls of the two groups of collection mechanisms arranged horizontally are made to face the flow direction of the water flow. Since the intervals of the guide fences arranged in combination are consistent with the flow direction of the water flow, the microorganisms carried in the water flow can enter the gaps of the guide fences and be captured by the filter fences. When the microorganisms enter the gaps of the guide fences, they will be adsorbed by the filter fences, and the microorganisms in the adsorbed state can pass through the outer end wall of the filter fence. At this time, the outer surface of the filter fence is set as a hollow grid structure. When the pore size is smaller than the opening When a hollow grid structure is provided, microorganisms will penetrate through the hollow grid structure and enter the closed structure formed by the center tube, the guide fence and the filter fence and cannot escape. A hollow grid structure is also provided on the outer end wall surface of the center tube, but the pore size of the hollow grid structure of the center tube is smaller than that of the hollow grid structure of the filter fence, so that microorganisms with smaller pore sizes can enter the inner cavity of the center tube. When the inner cavity of the center tube collects microorganisms, they can flow to the inner cavity of the connecting tube, so that the filtered and collected microorganisms are temporarily stored in the inner cavity of the collection tube. Through the reasonable design of the hollow grid structure and component settings, the microorganisms can be effectively captured and temporarily stored during the flow and collection process, thereby improving the collection efficiency. The equipment uses the power of the flowing water body to capture microorganisms and temporarily stores them in a specific inner cavity, ensuring that the microorganisms will not escape during operation, and has the characteristics of stability and reliability.

[0007] Preferably, the collection mechanism includes a collection clamp and a built-in groove opened on the side end surface of the collection clamp. The two groups of the collection clamps are connected in series through a collection tube at the interval. The other end of the connecting tube is laterally inserted into the outer end wall of the collection tube, so that the collection mechanism and the collection mechanism become a whole. When the water flow speed of the lake to be sampled is too slow or there is no obvious water flow, the collection mechanism as a whole is rotated with the outer end surface of the collection tube as a fulcrum until the multiple groups of guide bars and the soil are in a mutually perpendicular state. At this time, the water flow in the water body has no obvious flow, and the gaps in the multiple groups of guide bars can receive microorganisms deposited downward due to gravity. The collected microorganisms are in the same step as the flowing water body. The multiple groups of guide bars are arranged vertically with the soil by the rotation operation, effectively receiving the microorganisms deposited by gravity, ensuring the effectiveness and accuracy of microorganism collection. Through the rotation operation, the collection of microorganisms in low water flow rate or no water flow environment is realized, and the operation is simple and efficient.

[0008] Preferably, the auxiliary unit comprises a collecting baffle and a pushing mechanism installed on both sides of the outer end wall of the collecting baffle, and the inner cavity wall of the collecting baffle is inclinedly provided with a receiving mechanism.

[0009] Preferably, the pushing mechanism includes a frame plate and a frame body installed on the outer end surface of the frame plate, a pushing rod is inserted through the inner cavity of the frame body, and pushing blocks are provided at both ends of the pushing rod, and the set pushing rod is driven by an external driving motor to be pushed along the path of the frame plate and the setting position of the pushing block. Driven by the external driving motor, the pushing block and the collecting clamp block are linked, and the collection mechanism as a whole can be driven to run synchronously by the lifting and lowering of the pushing mechanism, so that the side end surface of the collecting clamp block is laterally inserted into the position of the positioning block interval for lifting and adjustment, and the microorganisms and impurities collected in the inner cavity of the collection cylinder are shaken. Microorganisms in the water are often attached to impurities or particulate matter in the water. The shaking collection process can help separate the microorganisms from the attachments, making the collected microorganisms purer, and the shaking can help fully suspend the microorganisms in the water, reducing the possibility of microorganism precipitation, which is helpful for subsequent analysis and detection work and improves data accuracy.

[0010] While shaking the microorganisms, the pushing block can push the water flow vertically in the water during the operation of the pushing mechanism as a whole, making the collected water flow slightly chaotic. By pushing the water flow vertically, the collected water body can be spread, increasing the coverage of the collection area, thereby more comprehensively collecting microbial samples in the water. By making the water flow slightly chaotic, the possibility of microorganisms in the water settling to the bottom can be reduced, keeping the microorganisms in a suspended state, which is beneficial to the collection operation.

[0011] Preferably, the receiving mechanism includes a vibration rod transversely installed on the inner cavity wall of the collection baffle frame and a sleeve tube sleeved on the outer ring of the vibration rod, the two sets of sleeve tubes are connected in series through a guide tube, and adjacent guide tubes are auxiliaryly connected through a connecting shaft.

[0012] Preferably, the sleeve includes a positioning plate and a positioning hole opened in the middle position of the positioning plate, two groups of the positioning plates arranged laterally opposite to each other are connected in series through a tube body, the inner cavity wall of the tube body is arranged with a trigger inner ring, the top of the receiving mechanism is arranged in an inclined state, and the outer surface of the sleeve can receive large impurities or plankton remaining in the water flow, the inclined guide cylinder and the associated shaft can guide the received large impurities or plankton into the inner cavity of the collection baffle and collect them, drop vertically downward and collect them in the gaps between the multiple groups of positioning blocks, the movably arranged positioning plate laterally penetrates the inner cavity of the insertion positioning hole, so that the outer surface of the vibration rod fits the inner end wall of the trigger inner ring, the self-shaking of the vibration rod is synchronized with the contact position of the trigger inner ring, at this time the vibration rod as a whole maintains a shaking state, at this time the water flow flowing through the receiving mechanism is in an accelerated running state, by accelerating the water flow, the content of pollutants remaining in the water can be effectively reduced, and the possibility of secondary pollution can be reduced, and in the accelerated running state of the water flow, the efficiency of collecting and treating large impurities or plankton in the water will be improved, which is beneficial to subsequent treatment and utilization.

[0013] Preferably, one end of the pushing block below is in contact with the upper end surface of the collecting clamping block, so that the operating unit and the auxiliary unit are combined into a whole.

[0014] Preferably, the bottom of the collecting baffle is inserted into the intervals between the four groups of positioning blocks, and the gap width between the outer end surface of the sleeve below and the inner cavity wall of the collecting baffle is not greater than the interval width of adjacent positioning blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The whole device is placed vertically and slowly with the operating unit as the bottom and the auxiliary unit as the top into the water area to be measured, and the four sets of positioning blocks are vertically inserted into the silt in the water area. When the flow rate of the water body to be collected is large, the outer end walls of the two sets of collection mechanisms arranged horizontally are facing the flow direction of the water. Through the reasonable design of the hollow grid structure and component settings, the microorganisms can be effectively captured and temporarily stored during the flow and collection process, thereby improving the collection efficiency. The equipment uses the power of the flowing water to capture microorganisms and temporarily stores them in a specific inner cavity, ensuring that the microorganisms will not escape during operation, and is stable and reliable.

[0016] When the water flow of the lake to be sampled is too slow or there is no obvious water flow, the collection mechanism as a whole is rotated with the outer end surface of the collection tube as the fulcrum until the multiple sets of guide bars and the soil are perpendicular to each other. At this time, there is no obvious flow of water in the water body, and the gaps between the multiple sets of guide bars can receive microorganisms that are deposited downward due to gravity. The collected microorganisms are in the same step as the flowing water. The multiple sets of guide bars are arranged vertically with the soil by rotating, effectively receiving microorganisms deposited by gravity, ensuring the effectiveness and accuracy of microbial collection. Through the rotating operation, the collection of microorganisms in low water flow or no water flow environment is realized, and the operation is simple and efficient.

[0017] The microorganisms and impurities collected in the inner cavity of the collection tube are shaken. Microorganisms in water are often attached to impurities or particles in the water. The shaking collection process can help separate the microorganisms from the attachments, making the collected microorganisms purer. Shaking can help fully suspend the microorganisms in the water, reducing the possibility of microbial precipitation, which is helpful for subsequent analysis and testing and improves data accuracy.

[0018] While shaking the microorganisms, the pushing block can push the water flow vertically in the water during the operation of the pushing mechanism as a whole, making the collected water flow slightly chaotic. By pushing the water flow vertically, the collected water body can be spread, increasing the coverage of the collection area, thereby more comprehensively collecting microbial samples in the water. By making the water flow slightly chaotic, the possibility of microorganisms in the water settling to the bottom can be reduced, keeping the microorganisms in a suspended state, which is beneficial to the collection operation.

[0019] The vibration of the vibration rod itself vibrates synchronously with the contact position of the trigger inner ring. At this time, the vibration rod as a whole maintains a shaking state, and the water flow flowing through the receiving mechanism is in an accelerated running state. By accelerating the water flow, the content of pollutants remaining in the water can be effectively reduced, and the possibility of secondary pollution is reduced. When the water flow is accelerated, the efficiency of collecting and treating large impurities or plankton in the water will be improved, which is conducive to subsequent treatment and utilization.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 8 Embodiment 1, a lake ecological environment monitoring sampling device, includes an operating unit 1 and an auxiliary unit 2, the auxiliary unit 2 is vertically arranged above the operating unit 1, the operating unit 1 includes four groups of arranged positioning blocks 11 and a collecting mechanism 12 interspersed at the interval between two adjacent groups of positioning blocks 11, a collecting mechanism 13 is vertically arranged at the outer end of the collecting mechanism 12, the collecting mechanism 13 includes a connecting tube 131 and a wrapping shell 132 sleeved on the outer circle of the connecting tube 131, and a guiding mechanism 133 is arranged on the other end face of the wrapping shell 132.

[0024] The guiding mechanism 133 includes a median tube 1331 installed at the center position of the side end surface of the wrapping shell 132 and a guiding fence 1332 arranged around the outer circle of the median tube 1331. A filter fence 1333 is arranged in a ring between each group of guiding fences 1332. The entire device is placed vertically and slowly into the water area to be measured with the operating unit 1 as the bottom and the auxiliary unit 2 as the top. The four groups of positioning blocks 11 are vertically inserted into the silt in the water area. When the flow rate of the collected water body is large, the outer end walls of the two groups of collection mechanisms 13 arranged horizontally are made to face the flow direction of the water flow. Because the intervals of the combined and arranged guiding fences 1332 are consistent with the flow direction of the water flow, the microorganisms carried in the water flow can enter the gaps of the guiding fences 1332 and be captured by the filter fences 1333. When the microorganisms enter the gaps of the guiding fences 1332, they will be adsorbed by the filter fences 1333. The microorganisms in the adsorbed state can pass through the outer end wall of the filter fence 1333. At this time, the outer surface of the filter fence 1333 is set as a hollow grid structure. When the aperture is smaller than the hollow grid structure, the microorganisms will pass through the hollow grid structure and enter the closed structure formed by the center tube 1331, the guide fence 1332 and the filter fence 1333 and cannot escape. The outer end wall surface of the center tube 1331 is also provided with a hollow grid structure, but the aperture of the hollow grid structure of the center tube 1331 is smaller than that of the hollow grid structure of the filter fence 1333, so that microorganisms with smaller apertures can enter the inner cavity of the center tube 1331. When the inner cavity of the center tube 1331 collects microorganisms, they can flow to the inner cavity of the connecting tube 131, so that the filtered and collected microorganisms are temporarily stored in the inner cavity of the collection tube 123. Through the reasonable design of the hollow grid structure and component settings, the microorganisms can be effectively captured and temporarily stored during the flow and collection process, thereby improving the collection efficiency. The equipment uses the power of the flowing water to capture microorganisms and temporarily stores them in a specific inner cavity, ensuring that the microorganisms will not escape during operation, and has the characteristics of stability and reliability.

[0025] In the second embodiment, the collecting mechanism 12 includes a collecting clamp block 121 and a built-in groove 122 provided on the side end surface of the collecting clamp block 121. The two groups of collecting clamp blocks 121 are connected in series through a collecting tube 123 at the interval. The other end of the connecting tube 131 is laterally inserted into the outer end wall of the collecting tube 123, so that the collecting mechanism 12 and the collecting mechanism 13 become a whole. When the water flow speed of the lake to be sampled is too slow or there is no obvious water flow, the collecting mechanism 13 is rotated as a whole with the outer end surface of the collecting tube 123 as a fulcrum until the multiple groups of guide bars 1332 and the soil are in a mutually perpendicular state. At this time, the water flow in the water body has no obvious flow, and the gaps between the multiple groups of guide bars 1332 can receive microorganisms deposited downward due to gravity, and the steps of the collected microorganisms and the flowing water body are consistent. The multiple groups of guide bars 1332 are arranged vertically with the soil by the rotation operation, effectively receiving the microorganisms deposited due to gravity, ensuring the effectiveness and accuracy of microorganism collection, and the collection of microorganisms in a low water flow rate or no water flow environment is realized through the rotation operation, which is simple and efficient to operate.

[0026] Embodiment 3, the auxiliary unit 2 includes a collecting baffle frame 21 and a pushing mechanism 22 installed on both sides of the outer end wall of the collecting baffle frame 21, the inner cavity wall of the collecting baffle frame 21 is inclinedly provided with a receiving mechanism 23, the pushing mechanism 22 includes a frame plate 221 and a frame body 222 installed on the outer end surface of the frame plate 221, the inner cavity of the frame body 222 is interspersed with a pushing rod 223, and both ends of the pushing rod 223 are provided with a pushing block 224, and the set pushing rod 223 is driven by an external driving motor to make it advance along the setting position of the frame plate 221 and the pushing block 224, and the pushing block 224 and the collecting clamping block 12 are driven by the external driving motor. 1 can be linked, and the collection mechanism 12 can be driven to run synchronously as a whole by lifting and lowering the pushing mechanism 22, so that the side end surface of the collection clamping block 121 is laterally inserted into the position of the interval of the positioning block 11 for lifting and lowering adjustment, and the microorganisms and impurities collected in the inner cavity of the collection tube 123 are shaken. Microorganisms in water are often attached to impurities or particles in the water. The shaking collection process can help separate the microorganisms from the attachments, making the collected microorganisms purer. Shaking can help fully suspend the microorganisms in the water, reduce the possibility of microorganism precipitation, and help subsequent analysis and detection work, and improve data accuracy.

[0027] Embodiment 4, while shaking the microorganisms, the pushing mechanism 22 is in operation as a whole, and the pushing block 224 can push the water flow vertically in the water, making the collected water flow slightly chaotic. By pushing the water flow vertically, the collected water body can be spread, and the coverage of the collection area can be increased, so that the microbial samples in the water can be collected more comprehensively. By making the water flow slightly chaotic, the possibility of microorganisms in the water settling to the bottom can be reduced, and the microorganisms can be kept suspended, which is beneficial to the collection operation.

[0028] In Example 5, the receiving mechanism 23 includes a vibration rod 231 installed transversely on the inner wall of the collection baffle 21 and a sleeve tube 232 sleeved on the outer ring of the vibration rod 231. The two sets of sleeve tubes 232 are connected in series through a guide tube 233, and adjacent guide tubes 233 are auxiliaryly connected through a connecting shaft 234.

[0029] The sleeve pipe 232 includes a positioning plate 2321 and a positioning hole 2322 opened in the middle of the positioning plate 2321. The two sets of positioning plates 2321 arranged opposite to each other in the horizontal direction are connected in series through the tube body 2323. The inner cavity wall of the tube body 2323 is arranged with a trigger inner ring 2324. The top of the receiving mechanism 23 arranged in an inclined state, the outer surface of the sleeve pipe 232 can receive large impurities or plankton remaining in the water flow. The inclined guide cylinder 233 and the associated shaft 234 can guide the received large impurities or plankton into the inner cavity of the collection baffle 21, collect them, and drop vertically downward to be collected in the gap between the multiple sets of positioning blocks 11. The movably arranged positioning plate 2321 is inserted transversely into the inner cavity of the positioning hole 2322, so that the outer surface of the vibration rod 231 fits against the inner end wall of the trigger inner ring 2324, and the self-vibration of the vibration rod 231 is synchronized with the contact position of the trigger inner ring 2324. At this time, the vibration rod 231 as a whole maintains a shaking state, and the water flow flowing through the receiving mechanism 23 is in an accelerated running state. By accelerating the water flow, the content of pollutants remaining in the water can be effectively reduced, and the possibility of secondary pollution can be reduced. When the water flow is accelerated, the efficiency of collecting and treating large impurities or plankton in the water will be improved, which is beneficial to subsequent treatment and utilization.

[0030] One end of the lower push block 224 is in contact with the upper end surface of the collecting clamping block 121, so that the operating unit 1 and the auxiliary unit 2 are combined into a whole.

[0031] The bottom of the collecting baffle 21 is inserted into the interval of the four sets of positioning blocks 11, and the gap width between the outer end surface of the lower sleeve 232 and the inner wall of the collecting baffle 21 is not greater than the interval width of the adjacent positioning blocks 11. To sum up: a lake ecological environment monitoring sampling device, includes an operating unit 1 and an auxiliary unit 2, the auxiliary unit 2 is vertically arranged above the operating unit 1, the operating unit 1 includes four groups of arranged positioning blocks 11 and a collecting mechanism 12 interspersed at the interval between two adjacent groups of positioning blocks 11, a collecting mechanism 13 is vertically arranged at the outer end of the collecting mechanism 12, the collecting mechanism 13 includes a connecting tube 131 and a wrapping shell 132 sleeved on the outer circle of the connecting tube 131, and a guiding mechanism 133 is arranged on the other end face of the wrapping shell 132.

[0032] The guiding mechanism 133 includes a median tube 1331 installed at the center position of the side end surface of the wrapping shell 132 and a guiding fence 1332 arranged around the outer circle of the median tube 1331. A filter fence 1333 is arranged in a ring between each group of guiding fences 1332. The entire device is placed vertically and slowly into the water area to be measured with the operating unit 1 as the bottom and the auxiliary unit 2 as the top. The four groups of positioning blocks 11 are vertically inserted into the silt in the water area. When the flow rate of the collected water body is large, the outer end walls of the two groups of collection mechanisms 13 arranged horizontally are made to face the flow direction of the water flow. Because the intervals of the combined and arranged guiding fences 1332 are consistent with the flow direction of the water flow, the microorganisms carried in the water flow can enter the gaps of the guiding fences 1332 and be captured by the filter fences 1333. When the microorganisms enter the gaps of the guiding fences 1332, they will be adsorbed by the filter fences 1333. The microorganisms in the adsorbed state can pass through the outer end wall of the filter fence 1333. At this time, the outer surface of the filter fence 1333 is set as a hollow grid structure. When the aperture is smaller than the hollow grid structure, the microorganisms will pass through the hollow grid structure and enter the closed structure formed by the center tube 1331, the guide fence 1332 and the filter fence 1333 and cannot escape. The outer end wall surface of the center tube 1331 is also provided with a hollow grid structure, but the aperture of the hollow grid structure of the center tube 1331 is smaller than that of the hollow grid structure of the filter fence 1333, so that microorganisms with smaller apertures can enter the inner cavity of the center tube 1331. When the inner cavity of the center tube 1331 collects microorganisms, they can flow to the inner cavity of the connecting tube 131, so that the filtered and collected microorganisms are temporarily stored in the inner cavity of the collection tube 123. Through the reasonable design of the hollow grid structure and component settings, the microorganisms can be effectively captured and temporarily stored during the flow and collection process, thereby improving the collection efficiency. The equipment uses the power of the flowing water to capture microorganisms and temporarily stores them in a specific inner cavity, ensuring that the microorganisms will not escape during operation, and has the characteristics of stability and reliability.

[0033] When the water flow rate of the lake to be sampled is too slow or there is no obvious water flow, the collection mechanism 13 is rotated as a whole with the outer end surface of the collection tube 123 as the fulcrum until the multiple sets of guide bars 1332 and the soil are in a mutually perpendicular state. At this time, the water flow in the water body has no obvious flow, and the gaps between the multiple sets of guide bars 1332 can receive microorganisms deposited downward due to gravity, and the collected microorganisms are in the same step as the flowing water body. The multiple sets of guide bars 1332 are arranged vertically with the soil by the rotation operation, effectively receiving microorganisms deposited by gravity, ensuring the effectiveness and accuracy of microorganism collection, and the collection of microorganisms in low water flow rate or no water flow environment is realized through the rotation operation, which is simple and efficient to operate.

[0034] The push rod 223 is driven by an external drive motor to advance along the path of the position where the frame 221 and the push block 224 are set. Driven by the external drive motor, the push block 224 is linked with the collection clamp 121, and the collection mechanism 12 can be driven to run synchronously as a whole by the lifting of the push mechanism 22, so that the side end surface of the collection clamp 121 is laterally inserted into the position of the interval of the positioning block 11 for lifting and adjustment, and the microorganisms and impurities collected in the inner cavity of the collection tube 123 are shaken. Microorganisms in the water are often attached to impurities or particulate matter in the water. The shaking collection process can help separate the microorganisms from the attachments, making the collected microorganisms purer. Shaking can help fully suspend the microorganisms in the water, reduce the possibility of microorganism precipitation, and help subsequent analysis and detection work, and improve data accuracy.

[0035] While the microorganisms are shaking, during the operation of the pushing mechanism 22 as a whole, the pushing block 224 can push the water flow vertically in the water, making the collected water flow slightly chaotic. By pushing the water flow vertically, the collected water body can be spread, increasing the coverage of the collection area, thereby more comprehensively collecting microbial samples in the water. By making the water flow slightly chaotic, the possibility of microorganisms in the water settling to the bottom can be reduced, and the microorganisms can be kept suspended, which is beneficial to the collection operation.

[0036] At the top of the receiving mechanism 23 which is set in an inclined state, the outer surface of the sleeve 232 can receive large impurities or plankton remaining in the water flow, and the inclined guide cylinder 233 and the associated shaft 234 can guide the received large impurities or plankton into the inner cavity of the collection baffle 21, and collect them, drop them vertically downward and collect them in the gap between the multiple groups of positioning blocks 11, and the movably set positioning plate 2321 penetrates the inner cavity of the insertion positioning hole 2322 horizontally, so that the outer surface of the vibration rod 231 fits the inner end wall of the trigger inner ring 2324, and the vibration of the vibration rod 231 itself vibrates synchronously with the contact position of the trigger inner ring 2324. At this time, the vibration rod 231 maintains a shaking state as a whole, and the water flow flowing through the receiving mechanism 23 is in an accelerated running state. By accelerating the water flow, the content of pollutants remaining in the water can be effectively reduced, and the possibility of secondary pollution can be reduced. In the accelerated running state of the water flow, the efficiency of collecting and treating large impurities or plankton in the water will be improved, which is beneficial to subsequent treatment and utilization.
