The precipitating generated after 4 dosing of the coagulative precipitation tank flocculation is discharged into sludge concentration tank 26, enters plate through sludge pump 27
Frame filter press 28, effluent recycling to collecting-tank 3, mud cake outward transport;The sludge that other each units generate is discharged by spoil disposal pipeline
Sludge concentration tank 23 enters plate and frame filter press 25, effluent recycling to conditioning tank 12, mud cake outward transport through sludge pump 24;
10 working method of air-floating apparatus is that the water outlet of coagulative precipitation tank 4 enters pressure air-dissolving tank 6 through air pressure pump 5,
It is passed through air into dissolving 6 simultaneously, opening pressure reducing valve 7 makes gas and water enter flotation tank, a large amount of fine gas bubbles is generated, in waste water
Substance similar in density and water attaches to bubble, is floated to wastewater surface, enters scum trough 8 through Slag Scraping Device 9, and in scum trough 8
Sludge be discharged into sludge concentration tank 23;
The characteristics of conditioning tank 12 has regulating pondage, uniformly walks water, flotation tank water outlet enters conditioning tank, lives simultaneously
Sewage enters conditioning tank by intake pump 11 and mixes with by pretreated coating waste-water.
The UASB15 is made of sludge reaction area, gas-liquid-solid three-phase separator 13 and gas chamber three parts.Have one in bottom
A high concentration, the Sludge Bed of high activity, sewage enter UASB15 from bottom to top, come into full contact in base sludge bed with sludge,
Organic substance in water matter becomes biogas by anaerobic fermentation.Biogas constantly merges in uphill process forms biggish bubble, sludge,
Water, biogas enter three phase separator 13 together, when biogas encounters the reflecting plate of separator lower part, are folded to the surrounding of reflecting plate, so
Water layer is passed through afterwards and enters gas chamber, concentrates on the export of gas chamber conduit 14, solid-liquid mixed liquor is by being reflected into three phase separator 13
Settling zone, the sludge in sewage flocculates, and particle is gradually increased, and is settled under the effect of gravity, and Sludge Bed is slid back to.Processing
