Abstract
The invention relates to a domestic sewage treatment device, belonging to the technical field of sewage treatment equipment. Domestic sewage automatically flows into a septic tank firstly; after the domestic sewage carries out anaerobic treatment in the septic tank, supernate is lifted up to an overhead water tank through a lift pump and then flows to a packing area of a membrane bioreactor through a liquid level balance box from the overhead water tank to be fully mixed with sludge on packing and floating sludge, and wastewater is purified through the metabolic activity of microorganism; the purified wastewater flows to a membrane module area through a middle division plate, and solid-liquid separation is realized through a suction pump; and clear water flows to a clear water reservoir for reuse, and concentrated liquid automatically flows back to the packing area. The pumping and stopping of a feed pump is controlled by a ball float valve. When the reactor needs to be repaired or discharge sludge, mixed liquid in the reactor flows back to the septic tank through a sludge discharging pipe. The overhead water tank, the membrane bioreactor and the clear water reservoir are arranged at a roof.
Description
Technical field:
The invention belongs to the waste disposal plant field, be specifically related to a kind of sewage treatment unit.
Background technology:
Along with city's development, it is more and more crowded that the city becomes, and sound pollution is also more and more serious, and oneself no longer is fit to bustling city centre live.So a part of rich choose owing to the water supply and the sewage emissions pipeline that do not have system away from the suburb of down town, causes water and sewage discharge difficult in the quiet and Air quality suburb inhabitation preferably away from the down town; In near sewage in the country house generally directly enters at present the river, so not only cause the pollution of surrounding environment, especially a kind of waste of water resources.
Combined film one biological reacting appliance have traditional activated sludge process incomparable many advantages; For example: to the removal efficient of organic pollutant is high, effluent quality is good, flow process is simple, compact construction etc.; The needs of water reuse demonstrate huge application potential in being well suited under current water resources critical shortage and with serious pollution background.City miscellaneous waters such as water outlet can be used to flush the toilet, road-cleaning, fire-fighting, afforestation, carwash, building operation.
Summary of the invention:
The objective of the invention is to disclose a kind of sewage treatment unit; Belong to technical field of sewage treatment equipment; Sewage flows automatically to septic tank earlier, and through after the anaerobic treatment, supernatant is promoted to elevated tank by lift pump at septic tank; Flow to packing area and the mud on the filler and the suspended sludge thorough mixing of membrane bioreactor by elevated tank via the liquid level equilibrium case again, the metabolic activity through mikrobe is purified waste water; Waste water after the purification flows to the membrane module district via central dividing plate, realizes solid-liquid separation through suction pump, and clear water flows to clean water basin in order to reuse, and liquid concentrator gravity flow backfill district.Taking out of intake pump stops being controlled by float(ing)valve.Need repairing or during spoil disposal, the mixed solution in the reactor drum flows back to septic tank via shore pipe at reactor drum.Elevated tank, membrane bioreactor and clean water basin all place roof.
For realizing objects of the present invention, adopt following technical scheme:
1. a sewage treatment unit is characterized in that mainly being made up of septic tank 1, lift pump 2, elevated tank 3, liquid level equilibrium case 4, membrane bioreactor 5, membrane module district 6, suction pump 7, clean water basin 9, float(ing)valve 10 and pneumatic pump 11; Wherein, Lift pump connects the water-in of septic tank 1 and elevated tank 3 respectively; The water outlet of elevated tank 3 connects the water-in of liquid level equilibrium case 4; After the water outlet of liquid level equilibrium case 4 was connected to membrane bioreactor 5, membrane module district 6 successively, by the inside in suction pump 7 one end junctional membrane assembly districts, and the other end connected clean water basin 9; Pneumatic pump is distinguished UNICOM to membrane bioreactor 5, membrane module district 6 internal ventilation separately as external assembly; The liquid level equilibrium case is provided with float(ing)valve 10 for 4 kinds.
2. described septic tank, the length and width height is respectively: 3 m, 2 m, 1 m.
3. described membrane module district adopts the PVC/PSF blend hollow fiber membrane, and membrane pore size is 0.1 μ m, and membrane flux adopts 0.25 m
3/ (m
2.d), membrane area is 8 m
2
4. described membrane bioreactor, the length and width height is respectively: 1.5 m, 1 m, 1 m.
