Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental engineering, in particular to an ecological intercepting well. BACKGROUND

[0002] The intercepting well is a key facility for controlling rain and sewage diversion in the drainage system, and is usually arranged at the end or key node of the combined sewerage network. Its core function is to intercept sewage to the sewage treatment plant on sunny days to prevent direct discharge of contaminated water into the water body; on rainy days, it limits part of the combined sewage into the receiving water body through devices such as weirs and gates, and the mixed sewage exceeding the design flow can be overflowed to reduce the load of the pipe network. The design of the intercepting well needs to consider factors such as interception multiple, water level difference, and anti-backflow, and common types include trough type, weir type, and pump control type. Modern intercepting wells are often equipped with intelligent monitoring systems to real-time control the interception flow, taking into account environmental protection and flood control safety, and are important transitional facilities in urban water environment management, especially suitable for drainage system reconstruction in old urban areas.

[0003] However, the conventional intercepting well has the following limitations and drawbacks: a. Single function, lack of ecological treatment, traditional intercepting wells rely only on mechanical gates or weirs for rain and sewage diversion, and cannot pretreat the sewage, which is directly discharged or transported to the sewage treatment plant, resulting in high load on the sewage treatment plant: large fluctuations in sewage concentration in residential areas, direct interception increases treatment cost. Waste of resources: nutrients such as nitrogen and phosphorus in sewage are not utilized, but require additional energy consumption for treatment; b. Low degree of intelligence, conventional intercepting wells rely on fixed weirs or manual control, and cannot dynamically respond to changes in water quality and quantity, rainwater overflow pollution: combined sewage is directly overflowed without screening, carrying suspended solids and pollutants into natural water bodies. Maintenance difficulties: lack of design for blocking debris, and debris easily blocks the pipeline, requiring frequent manual cleaning.

[0004] c. Lack of ecological compatibility, traditional design mainly uses concrete structures without vegetation or biological purification units, which cannot improve the surrounding ecological environment, and may even affect the experience of residents in the living area due to odors or mosquito breeding, and cannot improve the ecological environment.

[0005] Therefore, we propose an ecological intercepting well. SUMMARY

[0025] The linkage mechanism 2 further includes intercepting well water inlet pipe 21, the intercepting well water inlet pipe 21 penetrates the intercepting well body 1 and is fixedly connected with the intercepting well body 1, the inner side of the intercepting well body 1 is fixedly connected with electric control gate 22. The inner side of the intercepting well body 1 is provided with lifting pump 27, and the water suction pipe of the lifting pump 27 is communicated with the sewage connecting pipe 214.

[0026] In the embodiment, when rainwater or sewage enters the intercepting well body 1 through the intercepting well water inlet pipe 21, the flow meter 212 monitors the water inflow in real time, and the water quality sensor 213 synchronously detects the water quality parameters. If the water quality meets the rainwater standard and the flow does not exceed the set threshold, the electric control gate 22 remains open, and the water flow is directly discharged into the rainwater pipe network 4 through the intercepting well drainage pipe 215;When the water quality detection shows that the pollutants exceed the standard or the flow increases sharply, the electric control gate 22 is closed, and the lifting pump 27 is started at the same time, and the sewage is pumped to the sewage pipe network 5 through the sewage connecting pipe 214, and the pollutant composition of the sewage is detected by the water quality sensor 213 to determine whether the pollution concentration and the heavy pollution elements harmful to plants are distinguished by the water quality sensor 213, and the electromagnetic three-way valve 31 is started after the safety and concentration are determined to make the sewage enter the filter tank body 33 through the sewage connecting pipe 214, the electromagnetic three-way valve 31 and the filter tank water inlet pipe 32 for filtration.

[0027] In order to ensure the stable interception effect of the interception well body 1, a slag blocking net 26 is arranged in the interception well body 1, the slag blocking net 26 is high near one side of the floating baffle 25 and low away from the floating baffle 25. The inner wall of the interception well body 1 is also fixedly connected with a flow meter 212 and a water quality sensor 213, the flow meter 212 is close to the electric control gate 22. The inner side of the interception well body 1 is penetrated and fixedly connected with an interception well drain pipe 215, one end of the interception well drain pipe 215 away from the interception well body 1 is communicated with the rainwater pipe network 4.

[0028] In this embodiment, when it rains, the rainwater and the sewage are mixed to reduce the pollution concentration, and in the interception process, the floating baffle 25 floats with the water level, effectively intercepts the suspended impurities and guides the precipitation. The partition wall 23 of the linkage mechanism 2 ensures the stratified flow of the water flow, avoiding short flow. When the system detects the initial rainwater or small flow sewage, the electromagnetic three-way valve 31 switches the channel, so that the water flow enters the filter tank body 33 for ecological treatment through the filter tank inlet pipe 32. After the rain period, the water level in the interception well body 1 is lowered, and under the action of the drainage platform 28, the remaining rainwater will gradually drive the impurities into the slag blocking net 26, which is also convenient for subsequent maintenance of the interception well body 1, and can ensure the working efficiency of the interception well body 1.

[0029] In order to ensure the filtering effect of the filter tank 3, the inside bottom of the filter tank body 33 is filled with a gravel layer 310, the upper part of the gravel layer 310 is filled with a ceramsite layer 34, the upper part of the ceramsite layer 34 is filled with a sandstone layer 35, and the upper part of the sandstone layer 35 is filled with a vegetation layer 36. The filling layer in the filter tank body 33 is inserted with a leakage pipe 37, the number of the leakage pipe 37 is two groups, and the leakage pipe 37 close to one side of the filter tank inlet pipe 32 is penetrated and fixedly connected with the filter tank inlet pipe 32, and the top end of the leakage pipe 37 is higher than the vegetation layer 36. The side of the filter tank body 33 away from the filter tank inlet pipe 32 is penetrated and fixedly connected with a filter tank drain pipe 38, and the leakage pipe 37 close to one side of the filter tank drain pipe 38 is penetrated and fixedly connected with the filter tank drain pipe 38, the horizontal height of the filter tank drain pipe 38 is lower than the filter tank inlet pipe 32, and one end of the filter tank drain pipe 38 away from the filter tank body 33 is communicated with the rainwater pipe network 4. The surface of the leakage pipe 37 is surrounded by leakage holes, and the upper part of the filter tank drain pipe 38 is provided with a flow meter 39.

[0030] In this embodiment, the filter tank drain pipe 38 in the filter tank body 33 is provided with a flow meter 39, if the flow rate of the flow meter 39 is reduced, then the degree of the flow meter 212 in the interception well body 1 is verified to verify whether the filter tank 3 is blocked, so as to check the passing efficiency and the blocking condition of the filter tank 3, and also can realize dynamic control of the water inflow, and because the top end of the leakage pipe 37 is higher than the vegetation layer 36, the rainwater can flow away in time when it rains, without causing waterlogging.

[0031] Working principle: When rainwater or sewage enters the intercepting well main body 1 through the intercepting well inlet pipe 21, the flow meter 212 monitors the inlet flow in real time, and the water quality sensor 213 synchronously detects the water quality parameters. If the water quality meets the rainwater standard and the flow does not exceed the set threshold, the electric control gate 22 remains open, and the water flows through the intercepting well drain pipe 215 and is directly discharged into the rainwater pipe network 4; when the water quality detection shows that the pollutants exceed the standard or the flow surges, the electric control gate 22 is closed, and the booster pump 27 is started to pump the sewage through the sewage connecting pipe 214 to the sewage pipe network 5, and the water quality sensor 213 detects the pollutant composition of the sewage to determine whether the pollution concentration and the heavy pollution elements that harm plants are identified by the water quality sensor 213, and the electromagnetic three-way valve 31 is started to make the sewage enter the filter tank main body 33 through the sewage connecting pipe 214, the electromagnetic three-way valve 31 and the filter tank inlet pipe 32 for filtration.

[0032] It is worth noting that when it rains, the mixture of rainwater and sewage reduces the pollution concentration, and during the intercepting process, the floating baffle 25 floats up and down with the water level, effectively intercepting suspended impurities and guiding them to settle. The partition wall 23 of the linkage mechanism 2 ensures the layered flow of water, avoiding short flow. When the system detects initial rainwater or small-flow sewage, the electromagnetic three-way valve 31 switches the channel to make the water flow through the filter tank inlet pipe 32 into the filter tank main body 33 for ecological treatment. After the rain period, the water level in the intercepting well main body 1 decreases, and under the action of the drainage table 28, the remaining rainwater will gradually drive the impurities to flow into the residue retaining net 26, which is also convenient for subsequent maintenance of the intercepting well main body 1, and can ensure the working efficiency of the intercepting well main body 1.

[0033] In addition, the filter tank drain pipe 38 in the filter tank main body 33 is provided with a flow meter 39, and if the flow rate of the flow meter 39 decreases, the degree of the flow meter 212 in the intercepting well main body 1 is verified to determine whether the filter tank 3 is blocked, so as to check the efficiency and blockage of the filter tank 3, and dynamic control of the inlet flow can also be realized.
