As preferably, dehydration equipment is communicated with between solidification by travelling belt, and travelling belt is provided with the spray appliance for spraying soil-solidified-agent.
the beneficial effects of the utility model are:
1, the second bipolar settling tank of the present utility model is by the settling tank A be communicated with successively and coagulative precipitation tank A, and the settling tank B be communicated with successively and coagulative precipitation tank B forms, and the first bipolar settling tank is made up of separate first shallow lake pond A and first shallow lake pond B.In the process of cleaning mud, first can disconnect cleaning settling tank A and coagulative precipitation tank A for the second bipolar settling tank, after having cleared up mud wherein, return to working order, then clear up the mud in settling tank B and coagulative precipitation tank B; First can disconnect just pond, shallow lake A for the first bipolar settling tank, after having cleared up mud wherein, return to working order, then the mud in first pond, the shallow lake B of cleaning.Making settling tanks all in Sewage treatment systems clear up mud when isolating like this, in treating processes, can ensure that mud can not be discharged in physical environment or drinking-water system.
2, dehydration equipment of the present utility model is after by the sludge dewatering treatment in concentration basin, be delivered between solidification through travelling belt through travelling belt, the water being mixed with soil-solidified-agent is sprayed in mud by the spray appliance in course of conveying above travelling belt, after the soil-solidified-agent inside the mud piled up between solidification works, then the mud solidified is transported process.Mud through dehydration equipment process still contains a large amount of moisture, even be in the slurry condition of high density, just can be discharged in physical environment after must waiting the further drying of mud and go, the moisture that mud after soil-solidified-agent solidification treatment contains reduces in a large number, can be deposited in physical environment by finger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, the present embodiment provides a kind of bipolar urban sewage treatment system, comprise be communicated with successively grid, settling pit, the first bipolar settling tank, biological treatment tank, the second bipolar settling tank, efficient filter tank and sterilization pool, settling pit, the first bipolar settling tank with and the second bipolar settling tank be connected with concentration basin by slush pump, concentration basin is connected with dehydration equipment by slush pump, and concentration basin is connected with settling pit by pipeline with dehydration equipment.Dehydration equipment is communicated with between solidification by travelling belt, and travelling belt is provided with the spray appliance for spraying soil-solidified-agent.
First bipolar settling tank comprises separate first shallow lake pond A and first shallow lake pond B, and first shallow lake pond A is all communicated with settling pit, biological treatment tank with first shallow lake pond B.Second bipolar settling tank comprises the settling tank A and coagulative precipitation tank A that are communicated with successively, and the settling tank B be communicated with successively and coagulative precipitation tank B, settling tank A is all communicated with biological treatment tank with settling tank B, and coagulative precipitation tank A is all communicated with efficient filter tank with coagulative precipitation tank B.
First shallow lake pond A in first bipolar settling tank is all communicated with concentration basin by slush pump with first shallow lake pond B.First shallow lake pond A in first bipolar settling tank and the bottom surface of first shallow lake pond B are to recessed tapered bottom.Settling tank A in second bipolar settling tank, coagulative precipitation tank A, settling tank B are all communicated with concentration basin by slush pump with coagulative precipitation tank B.The bottom surface of the settling tank A in the second bipolar settling tank, coagulative precipitation tank A, settling tank B and coagulative precipitation tank B is to recessed tapered bottom.
With reference to figure 1, in implementation process, municipal effluent through some floating matters of large of grid filtering and other object, then through settling pit filtering macrobead object.Sewage enters first shallow lake pond A in the first bipolar settling tank and first shallow lake pond B, is sunk at the bottom of pond by most of mud.Sewage after preliminary sedimentation process enters biological treatment tank, utilizes bacterium in sewage, the aerobic of mould and anaerobism to process.
Sewage in biological treatment tank enters settling tank A and coagulative precipitation tank A successively, or enter settling tank B and coagulative precipitation tank B successively, mud remaining in sewage is sunk at the bottom of pond, enter efficient filter tank successively and sterilization pool does last filtration and disinfects through the water of precipitation process again, the water in sterilization pool is being discharged later through water quality detection is qualified.
First shallow lake pond A in the first bipolar settling tank and the storage mud in the pond B of first shallow lake more time, need to be processed in mud suction concentration basin by slush pump in time, first the connection of just pond, shallow lake A and settling pit is disconnected, enter in biological treatment tank in first pond, shallow lake A sewage at the middle and upper levels, disconnect the connection of just pond, shallow lake A and biological treatment tank again, then the center of the tapered bottom of just pond, shallow lake A is put into the tube end that mud taken out by slush pump, by mud suction concentration basin.After mud in the pond A of first shallow lake cleans out, first shallow lake pond A is returned to working order, then to the mud in the pond B of first shallow lake according to the method for method first shallow lake pond A clear up, return to working order again after the mud in the pond B of first shallow lake cleans out.
To the settling tank A in the first bipolar settling tank, coagulative precipitation tank A, and when the mud in settling tank B and coagulative precipitation tank B is cleared up, adopt the mode that the first bipolar settling tank cleaning mud is identical.
First shallow lake pond A, just pond, shallow lake B settling tank A, coagulative precipitation tank A, and the bottom surface of settling tank B and coagulative precipitation tank B is to recessed tapered bottom, the mud of bottom periphery under the influence of gravity can to tapered bottom center flow, contribute to the cleaning of mud, be also more prone to when labor cleaning is carried out to the mud be attached in the A bottom periphery of first pond, shallow lake.
In suction concentration basin, portion of water is wherein separated by mud, and parting liquid is entered in settling pit by pipeline and again processes.Mud in concentration basin is by slush pump suction dehydration equipment, and separated by the moisture of the overwhelming majority in mud, parting liquid is entered in settling pit by pipeline and again processes.Mud after processed is delivered between solidification through travelling belt, the water being mixed with soil-solidified-agent is sprayed in mud by the spray appliance in course of conveying above travelling belt, after the soil-solidified-agent inside the mud piled up between solidification works, then the mud solidified is transported process.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
