The water outlet of side, the water check valve is connected in coagulating basin by pipeline；Pipeline between the coagulating basin and positive permeability apparatus
Upper access has inlet valve, and the water inlet of the inlet valve accesses the water outlet of coagulating basin, the water outlet of the inlet valve by pipeline
Mouth accesses the water inlet of positive permeability apparatus by pipeline；The positive permeability apparatus includes that just infiltration biological reaction pool, positive infiltration are flat
Plate membrane module and positive osmotic drive liquid pool, the positive infiltration plate film assembly are vertically arranged in positive infiltration biological reaction pool and positive infiltration
Thoroughly between driving liquid pool；The water inlet of the sterilization pool is connected to by pipeline with positive osmotic drive liquid pool, and in the pipe of its connection
It is provided with driving liquid peristaltic pump on road, the water outlet of liquid peristaltic pump is driven to access the water inlet of sterilization pool by pipeline, it is described to disappear
Ultraviolet device is installed on malicious pond, is additionally provided with drain valve on the pipeline of the sterilization pool water outlet；Further include aeration pump and
Aeration tube, access has triple valve in the aeration tube, and the inlet end of the triple valve is connected to aeration pump, and the two of the triple valve
A outlet side is connected to coagulating basin and positive infiltration biological reaction pool respectively.
It further, further include first gas flowmeter and second gas flowmeter, the first gas flowmeter setting
On aeration tube between the one of output end of triple valve and coagulating basin, the second gas flowmeter setting is another in triple valve
On aeration tube between one output end and positive infiltration biological reaction pool.
Further, feed water flow meter is provided on the pipeline of the water outlet of the water check valve.
Further, heater and sewage stirrer are additionally provided in the coagulating basin, the heater is arranged in coagulation
The bottom in pond.
Further, the coagulation bottom of pond portion and positive infiltration biological respinse bottom of pond portion pass through pipeline and are communicated with mud mixing
Tank is pacified between the mud blending tank and coagulating basin and on mud blending tank and the positive pipeline permeated between biological reaction pool
Equipped with mud valve.
Further, the water outlet of the mud blending tank also passes through pipeline and is connected to cesspool, and connects on its pipeline
Enter to have sewage pump.
Positive infiltration domestic sewage processing method, including above-mentioned positive infiltration domestic sewage treatment device, the specific steps are that:
It is slightly larger that S1, the first sanitary sewage addition deodorant deodorization in cesspool, and process wide-meshed screen filter out volume
Substance then filters out small impurity by fine screen mesh, then will be by filtered sewage twice through intake pump and unidirectional water
Valve is introduced into coagulating basin；
Flocculant is added in coagulating basin and is flocculated using sewage stirrer stirring, the valve of triple valve is opened simultaneously by S2,
Air is introduced coagulating basin through aeration tube by aeration pump, is passed through 1~3h of air aeration in coagulating basin, stand 0.5 after the completion of aeration~
The sewage on coagulating basin top is introduced into positive infiltration biological reaction pool by 1h through inlet valve；
S3, it is positive to permeate the sewage in biological reaction pool after just infiltration plate film assembly processing, in the effect of permeable pressure head
Lower purification reaches positive osmotic drive liquid pool, and the water purification in positive osmotic drive liquid pool is through driving liquid peristaltic pump to be introduced into sterilization pool；
S4 after the water purification in sterilization pool is carried out ultraviolet radiation for sterilizing and disinfecting operation by ultraviolet device, opens drain valve,
Water purification after disinfection is expelled directly out from the pipeline of water outlet；
S5 opens mud valve, and the sludge in coagulating basin and positive infiltration biological reaction pool is being expelled to mud by pipeline
Blending tank carries out slurry dewatering processing after compressing sludge；
S6, the sewage that the sludge in mud blending tank is discharged after dehydration flows back into cesspool by sewage pump, de-
