It is equipped with inclined plate 221, the material of inclined plate 221 is PVC.Inclined plate 221 is obliquely installed side by side in parallel, and two pieces setting up and down of inclined plate 221
Plate, this two boards are connected on the side wall of settling zone 22, and inclined plate 221 is connected on this two boards, and inclined plate 221 passes through this two pieces
Plate is fixedly connected in settling zone 22.
Before sewage enters mixed zone 21, coagulant chemicals feeder 211 is controlled by solenoid valve 212 and thinks that addition is mixed in mixed zone 21
Solidifying agent, coagulant and sewage are sufficiently mixed in 21 region of mixed zone, are convenient for post precipitation.Mixed sewage enters settling zone
22, from bottom to top, settling zone 22 is uniformly laid with inclined plate 221 to water (flow) direction, is convenient for sludge settling.Sludge is arranged in 22 bottom of settling zone
Discharge pipe 222 excludes convenient for settled sludge.Supernatant after precipitating enters the second gathering ground 23.
It is provided with water pump and float switch in second gathering ground 23, water pump is connected with second pipe, float switch and water
Pump is connected.The sewage in gathering ground is pumped into pool bed depth purifying area 3 by water pump and float switch.The start and stop of water pump can be by
Float switch control, by the way that the operation of start-stop water pump for water level control is arranged, water pump is opened when water level is higher, water pump when water level is lower
It closes.
Pool bed depth purifying area 3 can be built on the basis of existing slight slope embankment, not be related to newly-increased land occupation, while not
Influence 4 flood passage of river.According to embankment actual conditions, the settable single-stage of pond-bed system or multistage purification structure, every grade for the treatment of facilities
Between pass through pipeline be connected to.
Every grade for the treatment of facilities includes the first gravel layer 31, the second gravel layer 32 and plantation layer 33 from bottom to top；First gravel
The filler of layer 31 and the second gravel layer 32 is gravel.In order to guarantee the supporting role of pool bed depth purifying area 3, the first gravel layer 31
Packing material size be greater than the packing material size of the second gravel layer 32, the thickness of the first gravel layer 31 is greater than the thickness of the second gravel layer 32
Degree improves the robustness of the first gravel layer 31, to improve the robustness of entire pool bed depth purifying area 3.Plantation layer 33 is filled out
Material is planting soil, and kind is implanted with hygrophyte on planting soil.
Pool bed depth purifying area 3 is mainly concrete structure, and three layers of filler of inside setting, bottom is the gravel of 50cm thickness,
Partial size is 10-15cm；Middle part is the gravel of 10cm thickness, partial size 5-8cm；Top is laid with the planting soil of 30cm thickness, plants beauty
The hygrophytes such as any of several broadleaf plants, cyperus alternifolius.
There are three the purification mechanism of pool bed depth purifying area 3 is main: the absorption of plant, the filtering of filler and microorganism drop
Solution.It by the degradation of three kinds of mechanism, further purifies water, sewage effluent is made to reach or approach " water environment quality standard "
(GB3838-2002) the IV class standard in.By pool bed depth purifying area 3 treated water outlet be discharged into river 4, can effectively mitigate
Pollution to river.
The present invention is as a kind of confluence of rainwater and sewage conduit wastewater Treatment process for cutting dirty region for inconvenient progress pipeline, not only
It can satisfy conventional design demand, the treatment effect of sewage can also be further increased, mitigation accounts for by the rational design of system
Ground pressure reduces cost of labor.
The confluence of rainwater and sewage conduit wastewater collection and treatment device in actual application, in non-heavy water inlet pipe 111
The sewage row after fine fack mouthful enters the first gathering ground 12；Heavy sewage is discharged with a large amount of rainwater from water inlet pipe 111,
Part enters the first gathering ground 12, and when it is that rainfall is larger that water level, which rises, mixed rain sewage is discharged by outlet pipe 112, is led to
It crosses third pipeline and introduces pool bed depth purifying area 3.Water pump is set inside first gathering ground 12, by the water pump in the first gathering ground 12
Enter treatment tank 2.
Before sewage enters mixed zone 21, coagulant is added by chemicals feeder and the control of solenoid valve 212.Mixed sewage into
Enter settling zone 22, from bottom to top, settling zone 22 is uniformly laid with PVC inclined plate 221 to water (flow) direction, convenient for sedimentation.22 bottom of settling zone
Sludge discharge pipe 222 is set, is excluded convenient for settled sludge.Supernatant after precipitating enters the second gathering ground 23, the second collection
Sewage pump is set inside pool 23, the water in the second gathering ground 23 is pumped into pool bed depth purifying area 3.
Pool bed depth purifying area 3 can be built on the basis of existing slight slope embankment, not be related to newly-increased land occupation, while not
Influence 4 flood passage of river.According to embankment actual conditions, the settable single-stage of pond-bed system or multilevel structure.Purifying area is mainly coagulation
Soil structure, inside three layers of filler of setting are further purified water by the degradation of three kinds of mechanism, and sewage effluent is made to reach or connect
Nearly IV class standard.Treated, and water outlet is discharged into river 4, can effectively mitigate the pollution to river.
In addition, what confluence of rainwater and sewage conduit wastewater collection processing can be realized by height difference in the occasion that orographic condition allows
The gravity flow of rainwater, sewage between apparatus system reduces energy consumption, reduces controlling unit, that is, can according to the actual situation will be several
A confluence of rainwater and sewage conduit wastewater collection and treatment device connection.
The above is only the embodiment of the present invention, are not intended to limit the scope of the invention, all to be said using the present invention
Equivalent structure or equivalent flow shift made by bright book and accompanying drawing content is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
