Technical field
The utility model relates to a kind of Sewage treatment systems, is specifically related to a kind of food wastewater integrated equipment for wastewater treatment.
Background technology
Raw materials for food industry is extensive at present, and goods are of a great variety, makes that the water yield, the water quality of discharging waste water are widely different.Principal pollutant have (1) to swim in solid matter in the waste water in the waste water, as dish leaf, pericarp, meat mincing, fowl plumage etc.; (2) be suspended in material in the waste water such as grease, protein, starch, colloidalmaterial etc.; (3) be dissolved in acid in the waste water, alkali, salt, carbohydrate etc.; (4) silt particle carried secretly of raw material and other organism etc.; (5) bacterium etc. that causes a disease.This shows that the characteristics of food industrial wastewater are organic substance and suspension content height, easily corrupt, generally there is not big toxicity.Its harm mainly is to make body eutrophication, so that causes hydrocoles and fish kills, impels the organism of subaqueous deposit to produce stink, worsens water quality, contaminate environment.
Existing food wastewater treatment system is generally the concrete structures treatment system, and its technical process of adopting is grille well-oil trap-equalizing tank-air flotation pool-settling tank-coagulation reaction tank-tube settler-anaerobic pond-Aerobic Pond-settling tank-filtering basin-clean water basin-standard discharge.
But because contaminants in food is more, organic concentration is higher, and lower through organic removal rate behind air supporting and the one-level biochemistry, outlet water organic substance concentration is higher, and suspended substance is more.Draw by analysis, sewage effluent quality range estimation after air-flotation system is handled is better estimated relatively poor through water quality after the biochemical treatment; Through detecting, organic concentration obviously reduces in the sewage of air-flotation system processing back, and after follow-up one-level biochemical system was handled, the organic concentration clearance was lower, and suspended substance increases.Therefore determine to cause the relatively poor link of sewage effluent quality to be: the biochemical system microbial decontamination processes.
And by concrete brick mix structure or steel and concrete structure, adopt earth excavation and use settings such as reinforcing bar, concrete, brick, need higher cost and manpower to be built into, it is big to make labour intensity.And structures are removed, more during problem such as exchange device, can only be discarded running into enterprise.
Summary of the invention
