Below in conjunction with preferred embodiment; Details are as follows to the embodiment that provides according to the utility model: see accompanying drawing for details; A kind of integral type countryside sewage treatment equipment; Be made up of sewage collecting pool 1, biological treatment system 2, sludge sump 3, said sewage collecting pool is communicated with biological treatment system 2 through carrying water pump 4; Said biological treatment system comprises anoxic pond 5, anaerobic pond 6, Aerobic Pond 7, second pond 8, sterilization pool 16, the sand filtering system that is arranged in order from left to right and is communicated with; Said sludge sump places on anoxic pond and the anaerobism pool side and is connected with second pond through air-lift device 11.Be respectively equipped with vertical stirrer 15 in said anoxic pond 5, the anaerobic pond 6, be provided with air-lift device 10 in the said Aerobic Pond 7 mud mixture is delivered to anoxic pond, be provided with air-lift device 11 in the said second pond 8.Be provided with spherical aeration head 14, air-lift device 10 in the said Aerobic Pond and to the gas blower 13 of Aerobic Pond and air-lift device air feed, said aeration head is installed at the bottom of the pond of Aerobic Pond.Be provided with the air-lift device 11 that second pond mud is delivered to anoxic pond and sludge sump in the said second pond.Be provided with the spherical aeration head 14 that is installed at the bottom of the sludge sump pond in the said sludge sump, said sludge sump is provided with the gas blower 13 to the sludge sump air feed.Water-in in the said sewage collecting pool is provided with filtering grid 12, is provided with submersible agitator 9 in the pond and carries water pump 4.Said sand filtering system is provided with sand filtering basin 18, backwash pond 17, backwashing pump 19.Said backwashing pump washes the sand filtering basin with the water in the backwash pond.
Working process:
Domestic sewage in rural areas by using gets into sewage collecting tank through unified collection of sewer line, and one group of filtering grid is set before inlet, removes foreign material, guarantees that waste disposal plant is normal.A whisking appliance is set in sewage collecting tank, reaches the purpose of even water quality, regulating pondage.Through carrying water pump that waste water is delivered to biological treatment system, adopt anaerobism, anoxic, the aerobic treatment process that combines.Waste water at first gets into the oxygen-starved area, gets into anaerobic zone then, gets into aerobic zone again and carries out aerobic treatment; Aerobic zone will add Moveable packings, and the Moveable packings effective ratio area of employing is 500 metre squared per cubic, can make mikrobe very effective breeding on the surface; Significantly reduce the volume of biological reaction tank; And Moveable packings can increase and decrease dosage at any time according to variation of water, and does not need extra change device, has increased the handiness of waste disposal plant greatly.
Through aeration, let filler and muddy water thorough mixing, microbial film is adhered at filling surface, increased impact resistance and the processing power of mikrobe greatly.Aeration head adopts spherical aerator, it can about its position, about simultaneously to Aeration in the water, increase greatly than semisphere or flat aeration rate, simultaneously downward gas disturbance the deposition under the pond, increased the effect of pond mesophytization bacterium greatly.Make each position, whole aeration zone that inflation all arranged, avoid occurring the dead band, and add Moveable packings, form fluid bed biological film reactor drum (MBBR) in the aeration zone.Get into second pond then; Clear water is to sterilisation system through second pond post precipitation surface, carries out disinfection and removes bacterium, the intestinal bacteria in the water through adding Youxiaolin, gets into the sand filtration system then; Further remove SS; The sand filtration unit can pass through gas, water backwash, and with recycling, backwash water directly is back to the wastewater collection pond and handles to do again.The excess sludge of biosystem then can be disposed to the mud collecting tank, does Unified Treatment.During operation, mud external reflux and internal reflux will be used as mud external reflux and internal reflux through air-lift device alternative transport water pump, save the maintenance cost and the operation electricity charge of water pump greatly.Water outlet through the sand filtration system promptly can be used for flushing the toilet, green area irrigation etc., to practice thrift urbanite water consumption.System's water outlet also can directly be disposed to the river course.
