In the 1970s, scientists discovered that microorganisms can absorb phosphorus under aerobic conditions and release phosphorus under anaerobic conditions in the presence of organic matter. The biological treatment method for phosphorus-containing wastewater has been gradually formed and improved on this basis. Biological methods such as A / O, A2 / O, and UCT processes are mainly suitable for treating low-concentration and organic phosphorus-containing wastewater. Chemical methods mainly include coagulation and sedimentation, crystallization, ion exchange adsorption and other processes, which are mainly suitable for treating inorganic phosphorus-containing wastewater.

The outer wall of the raised plate is fixedly connected with the filter net one, and the top of the shell two is fixedly connected with the water inlet component, and the outer wall of the shell two is fixedly connected with the regulating component. By setting a pretreatment mechanism, the water that has passed the initial filtration is allowed to enter the shell two, and the water is filtered for the second time to remove some fine debris. Since the horizontal height of the water inlet in the shell two is low, and the height of the filter net one is high, it is difficult for the debris remaining during the filtration of the equipment to accumulate on the filter net one, thereby avoiding the blockage of the filter net one and improving the stable operation of the equipment.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The present invention sets a water inlet component to prevent the external water from entering the equipment. Under the action of the filter screen 2, larger debris is blocked outside the equipment. However, with the long-term use of the equipment, in order to prevent the debris from accumulating in the accessories of the water inlet component of the equipment, the connecting groove and the connecting pipe are used to allow the debris to flow to both sides of the equipment through the pipeline, so that the component can filter while preventing the debris from accumulating near the equipment entrance.

[0018] 2. The present invention sets a pre-treatment mechanism to allow the water that has passed the initial filtration to enter the outer shell 2, and performs secondary filtration on the water to remove some fine debris. Since the horizontal height of the water inlet in the outer shell 2 is low and the height of the filter screen 1 is high, it is difficult for the residual debris during the filtration of the equipment to accumulate on the filter screen 1, thereby avoiding the blockage of the filter screen 1 and improving the operation stability of the equipment.

[0019] 3. The present invention sets a pretreatment mechanism. With the long-term use of the equipment, impurities filtered out of the outer shell 2 will accumulate there. Therefore, it is necessary to open the partition under the raised plate and discharge the water and debris in the outer shell 2 from the equipment through the outlet 1 to avoid the accumulation of debris.

[0020] 4. The present invention sets an adjustment component. As the equipment is used, it is necessary to control the flow rate of water entering the equipment to avoid the water entering the equipment too quickly, resulting in the previous water not being processed yet while the subsequent water has entered, which affects the treatment effect of the equipment.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a dephosphorization and denitrification treatment device for an open water body, comprising a shell 1, the outer wall of the shell 1 is fixedly connected with a floating plate 101, through the device of the floating plate 101, the whole device can float on the surface of the open water body, which is convenient for the placement of the device, the outer wall of the shell 1 is fixedly connected with a water outlet 102, the water outlet 102 is used to discharge the water with impurities in the cavity 206, and avoid the accumulation of impurities on the inner wall of the device, the side of the shell 1 away from the water outlet 102 is fixedly connected with a water outlet 2 103, the water outlet 2 103 is used to discharge the water treated by the treatment box 104, the inner wall of the shell 1 is fixedly connected with the treatment box 104, and also includes:

[0033] The pretreatment mechanism 2 includes a shell 201 fixedly connected to the inner wall of the shell 1, and both sides of the outer wall of the shell 201 are fixedly connected with a connecting shell 1 202. The inner walls of the two connecting shells 202 are provided with connecting ports 204. The two connecting ports 204 penetrate the connecting shell 1 202 and extend to the inner wall of the shell 201. The bottom of the connecting shell 202 is fixedly connected with a connecting pipe 203. The end of the connecting pipe 203 away from the connecting shell 1 202 is fixedly connected to the processing box 104. The inner wall of the shell 201 is fixedly connected with a raised plate 205. Through the raised plate 205, after the water body enters the interior of the equipment, it cannot directly enter the subsequent processing box 104, but must overflow the raised plate 205 to pass through. This makes it difficult for impurities in the water to be blocked under their own weight. The impurities are not on the filter net, but are accumulated at the connection between the shell 201 and the partition 208 under the action of water flow, so as to ensure that the filter net 209 will not be blocked. A cavity 206 is provided at the bottom of the raised plate 205, and the cavity 206 is connected with the inner wall of the shell 201. The inner wall of the raised plate 205 is fixedly connected with a push rod 207 for controlling the switch of the partition 208. The end of the push rod 207 away from the raised plate 205 is fixedly connected with the partition 208. The outer wall of the partition 208 is movably connected with the raised plate 205, and the outer wall of the raised plate 205 is movably connected with the shell 201. The outer wall of the raised plate 205 is fixedly connected with a filter net 209 for filtering impurities. The top of the shell 201 is fixedly connected with a water inlet component 21, and the outer wall of the shell 201 is fixedly connected with an adjustment component 22.

[0034] The working principle of this embodiment is as follows: after the water body is initially filtered by the water inlet component 21, the water will enter the outer shell 201. As the water body enters, the height of the water will slowly overflow the height of the raised plate 205. After being filtered by the filter net 209, the water flows into the connecting shell 202 through the connecting port 204, and then flows to the treatment box 104 through the connecting pipe 203 for treatment. The remaining impurities are applied to one end of the accumulation, and the push rod 207 is started to lift the partition. In this way, the water body cannot overflow the raised plate 205, but enters the cavity 206, and is discharged out of the equipment through the water outlet 102.

[0035] Embodiment 2 is different from Embodiment 1 in that: Figure 6-Figure 7As shown, the water inlet component 21 includes a connecting shell 211, the outer wall of the connecting shell 211 is fixedly connected to the outer shell 201, the end of the filter screen 1 209 away from the protruding plate 205 is fixedly connected to the connecting shell 211, the end of the connecting shell 211 away from the outer shell 201 is fixedly connected to the outer shell 3 212, the bottom of the outer shell 3 212 is fixedly connected to the outer shell 201, the outer wall of the outer shell 3 212 is fixedly connected to the outer shell 1, and the end of the outer shell 3 212 away from the connecting shell 211 is fixedly connected to the protruding plate 213. The water inlet and outlet parts of the component are isolated by the protruding plate 213 to avoid the water flow generated by the water inlet and the water outlet from affecting each other, resulting in the inability to discharge debris well, and the inner wall of the outer shell 3 212 A connecting groove 214 is provided, and a connecting plate 215 is fixedly connected to the inner wall of the outer shell three 212, and a filter screen two 216 is fixedly connected to the outer wall of the connecting plate 215. Since the filter screen two 216 is in a convex arc shape, it is difficult for debris to accumulate in the middle part of the filter screen two 216. Instead, it moves to both sides of the filter screen two 216 under the action of the water flow, which provides a basis for subsequent debris to flow to the connecting pipe 217. A connecting pipe 217 is fixedly connected to the side of the connecting plate 215 away from the filter screen two 216, and the outer wall of the connecting pipe 217 is fixedly connected to the connecting groove 214. A partition two 218 is movably connected to the inner wall of the connecting shell two 211, and a sealing strip 219 is fixedly connected to the bottom of the partition two 218.

[0036] The working principle of this embodiment is as follows: after the device is placed in water, water will enter from the opening of the outer shell three 212, and under the filtration of the filter net two 216, debris will be blocked outside and the connecting pipe 217 will be suppressed to flow to the outside, and the filtered water will enter the outer shell two 201 through the connecting shell two 211.

[0037] Embodiment 3 is different from Embodiment 1 and Embodiment 2 in that: Figure 8As shown, the adjustment component 22 includes a base 221, the outer surface of the second housing 201 is fixedly connected to the base 221, a trigger button 222 is fixedly connected to the side of the base 221 away from the second housing 201, the inner wall of the base 221 is movably connected to a trigger plate 223, the top of the trigger plate 223 is fixedly connected to an elastic component 224, one end of the elastic component 224 away from the trigger plate 223 is fixedly connected to the base 221, the top of the base 221 is rotatably connected to a push rod 225 through a bearing, the end of the push rod 225 away from the base 221 is rotatably connected to the second partition 218 through a bearing, and the second housing 201 is fixedly connected to the second partition 218 through a bearing. 1 is fixedly connected to a sliding column 226, an outer wall of the sliding column 226 is movably connected to a sliding plate 227, an end of the sliding plate 227 away from the sliding column 226 is fixedly connected to a U-shaped rod 228, an outer wall of the U-shaped rod 228 is movably connected to a slider 229, an outer wall of the slider 229 is fixedly connected to the connecting shell 1 202, an end of the U-shaped rod 228 away from the sliding plate 227 penetrates the connecting shell 1 202 and extends to the interior of the connecting shell 1 202, an outer wall of the U-shaped rod 228 is movably connected to the connecting shell 1 202, and an end of the U-shaped rod 228 away from the sliding plate 227 is fixedly connected to a floating plate 2210.

[0038] The working principle of this embodiment is as follows: as the device is used, water will be continuously sent into the treatment box 104 through the connecting shell 1 202 and the connecting pipe 203. When there is too much water in the treatment box 104, it will remain in the connecting shell 1 202, which will drive the floating plate 2210 to rise together. As the floating plate 2210 rises, the sliding plate 227 is driven to move upward under the action of the U-shaped rod 228. When the sliding plate 227 squeezes the trigger button 222, the push rod 225 will shrink by half, reducing the speed of water entering the device. When the sliding plate 227 squeezes the trigger plate 223, the push rod 225 will shrink completely, completely blocking the water inlet and preventing water from entering until the previous water treatment is completed. After the water level in the connecting shell 1 202 drops, the sliding plate 227 no longer squeezes the trigger button 222 or the trigger plate 223, the push rod will be pushed out again, and the water can re-enter the device.
