Embodiment
Referring to accompanying drawing, dispersed wastewater enters pretreating zone 1 and anaerobic zone 2, under anaerobic pre-treatment through collecting from water-in 1-2.Because water yield instability, the water level of pretreating zone 1 changes.When coming the water yield many, pretreating zone 1 is in high-water, and when coming the water yield few, pretreating zone 1 is in low-water level.This water level changes significantly will make the aerobic filler 4-2 of aerobic zone 4 flood a little while, lack of water a little while, and air pump is running light under exsiccosis, consumes the power of aeration in vain, influences treatment function.Therefore a dividing plate is being arranged between anaerobic zone 2 and aerobic zone 4, rely on contiguous anaerobic zone 2 dividing plates one side Pneumatic water pump 3 that water is promoted and be transported to aerobic zone 4, make aerobic zone 4 remain constant water level and basicly stable feed flow, this is very important for the operating performance that improves integrated decentralized wastewater treatment unit.
In the sewage that Pneumatic water pump 3 submergences and needs promote, from the inlet pipe introducing pressure air, its pressure being arranged is P1.The maximum hydrostatic pressure in pond depends on the height of water in the pond, and maximum hydrostatic pressure is P2.Water tank 3-3 pressure inside P1 is greater than the hydrostaticpressure P2 in pond at this moment, and check valve 3-5 closes automatically.The water of water tank 3-3 inside is entered water shoot 3-4 by pressure-driven, rises to the height that needs and discharges.
Water in the water tank 3 constantly is discharged from, and the water level in the water tank 3-3 constantly descends.When water level subcritical line a, the pressed gas in the water tank 3-3 enters water shoot 3-4 emptying from U-shaped pipe 3-2.The interior pressure of water tank 3-3 this moment is P3, P3<P2, and check valve 3-5 opens automatically.Water in the pond flows into water tank 3-3 fast.When the water level in the water tank 3-3 was higher than critical line b, the water in the water tank 3-3 flowed into U-shaped pipe 3-2 water tank 3-3 this moment pressure inside rapidly and rises to P1 rapidly, and check valve 3-5 closes automatically.The water of water tank 3-3 inside is entered the height discharge that water shoot 3-4 rises to be needed by pressure-driven once more.
Above process constantly circulates repeatedly.Under the condition of continuous air feed, water shoot 3-4 constantly has water to discharge.Can realize the automatic adjusting of Pneumatic water pump aquifer yield by regulating air input.The Pneumatic water pump water outlet is even, can satisfy small-sized centralized waste disposal plant for the uniform requirement of water outlet.
Compare with existing small-sized centralized sewage disposal device, adopt the small-sized centralized sewage disposal device of Pneumatic water pump to have the following advantages:
1, the little water yield that requires of small-sized centralized sewage disposal device is evenly intake.Require flooding quantity at 0.25~1.0 cubic metre/hour, common water pump can not meet the demands.Adopt the small-sized centralized sewage disposal device of Pneumatic water pump the little water yield evenly to intake, improve processing efficiency.
2, the air-lift device efficient that generally adopts at present is low, if adopt common little water pump, efficient about 30~40%.Adopt the small-sized centralized sewage disposal device of Pneumatic water pump owing to adopt positive displacement, efficient surpasses 〉=90% in theory
3,, adopt the small-sized centralized sewage disposal device device of Pneumatic water pump not have moving parts, not wearing and tearing than long work-ing life.Except that check valve needed regular maintenance, other parts were non-maintaining.The theoretical life-span at least 〉=20 year.
Practical effect:
The small-sized centralized sewage disposal device that adopts Pneumatic water pump is through experiment, and the result is satisfactory.For example: the even water inlet that can solve 5 tons of equipment (every day treatment capacity, lift height 1 meter) with the little Pneumatic water pump of 9W.
According to above test-results, adopt the small-sized centralized sewage disposal device of Pneumatic water pump can adapt to treatment capacity at 5~20 tons/day small-sized centralized sewage treatment unit.
Under the stable condition of feed flow, the function of aerobic zone 4 is in optimum regime, and pollutent is effectively decomposed removal at this.
Dephosphorization electrode 4-1 adopts iron plate and aluminium sheet as electrode.Iron ion that electrolysis produces and aluminum ion combine with phosphorus in the sewage and form the throw out removal.Recoil aeration tube 4-5 regularly recoils, and eliminates throw out.Sludge carrier pipe 5-4 regularly will precipitate the sedimentary mud of sterilizating area and reflux.Drug storage bucket 5-1 is arranged among the disinfection room 5-2, wherein store disinfectant.Water outlet is flowed out discharging through the sterilization back from water relief outlet 3-8.
The utility model is stable effective.In the rural area or the municipal sewage pipe network difficulty receive the zone that reaches, integrated dispersed wastewater treatment unit is a kind of mode of suiting measures to local conditions to handle dispersed wastewater.
