Under be up divided into the 104, second anaerobic zone 110, the 102, first anaerobic zone, mixed zone, settling zone 106,
Gas-liquid separation zone 108, described lower end, mixed zone 102 is provided with water inlet 101, the first described anaerobic zone 104
It is respectively equipped with the first return duct 112 and the second return duct 111, the first described anaerobism with the second anaerobic zone 110
District 104 and the second anaerobic zone 110 further respectively have the first biogas pipe 103 and the second biogas pipe 105, described
Settling zone 106 is provided with outlet 109, and described upper end, gas-liquid separation zone 108 is provided with firedamp drainage mouth 107,
It is the most downward-sloping and close that lower end is provided with return duct 113, the first described return duct 112 and the second return duct 111
Circulation to mixed zone 102, described first return duct the 112, second return duct the 111, first biogas pipe 103,
Second biogas pipe 105 is each provided at outside anaerobic reactor, and described return duct 113 is from gas-liquid separation zone 108
Mixed zone 102 is led in bottom, and the first described biogas pipe 103 and the second biogas pipe 105 collaborate and lead to gas-liquid
Disengagement zone 108, the water inlet pipe 202 that described air-flotation system includes flotation tank 201, is located on flotation tank 201,
Described flotation tank 201 is arranged over scraping slag band 204, and described scrapes slag band 204 two ends connection rotating shaft one respectively
203 and rotating shaft 2 207, described rotating shaft 2 207 connects the power transmission shaft 210 of motor 211 by belt one,

Real work room, the sanitary wastewater in community is converged by pipeline and enters in grille well, passes through grille well
Being separated by some big foreign material and get rid of, waste water is squeezed into anaerobic reactor by pump and is carried out preliminary treatment afterwards, detests
Water after oxygen process enters in sedimentation tank and precipitates, and the mud wherein precipitated enters in sludge-tank,
Water then enters air-flotation system, and part of contaminated water then passes back into anaerobic reactor and continues with, and enters air-flotation system
Carry out the another stepping of the water after the removal of impurity to enter sterilization pool and carry out disinfection, and the scum silica frost discharged in air-flotation system is same
Enter in sludge-tank, sterilization pool can add medicine to water disinfection, the most again water be squeezed into reuse
Pond is for intra-cell users, though these water can not be eaten, but substantially can reach general article-cleaning, pouring
The purposes such as plant, significantly alleviate the pressure of domestic water, have saved water resource.
During anaerobic reactor work, sewage is injected device mixed zone anyway by water inlet, now, water,
The mud mixture of grain mud and gas-liquid separation zone backflow mixes in this district effectively, the muddy water that mixed zone is formed
Mixture enters the first anaerobic zone, and under high concentration sludge effect, major part Organic substance is converted into biogas, mixed
In on conjunction liquid, the violent disturbance of up-flow and biogas makes this reaction zone, mud is in expanding and fluidized state, strengthens mud
Water surface contacts, and mud remains high activity therefrom, along with increasing of biogas output, a part of muddy water
Mixture is promoted to the gas-liquid separation zone at top by the first biogas pipe, and mud is returned to mixing by the first return duct
District, the mixed liquor through the first anaerobic zone enters back into the second anaerobic zone, and this district's sludge concentration is relatively low, and waste water
Middle major part Organic substance is degraded in the 1st anaerobic zone, and therefore biogas generation amount is less, but still has a small amount of natural pond
Gas enters gas-liquid separation zone through the second biogas pipe, and mud is returned to mixed zone by the second return duct, through 2 times
The mixed liquor of anaerobic reaction finally enters settling zone and precipitates, and top clear water is discharged by outlet, precipitation
Granule sludge sinks to the biogas entrance gas-liquid separation that the second anaerobic zone, the first biogas pipe and the second biogas pipe promote
District separates, and the biogas after separation is discharged by firedamp drainage mouth, and mud mixture then returns along return duct
To the mixed zone of bottom, mud and water inlet with reactor bottom are sufficiently mixed, it is achieved that mixed liquor interior
Portion is circulated.
During air-flotation system work, release head bottom flotation tank produce the impurity in bubble, with water merge and incite somebody to action
It takes on the water surface, then these impurity absorption is taken away by scraping slag band, scrapes slag band and is run by driven by motor, when
When driven by motor scrapes slag band counterclockwise movement, drive slag scraper counterclockwise movement, scraping above slag scraper simultaneously
Cutter will be cleared up scraping slag band simultaneously, saves manpower, time.
