Description
Technical field
The present invention relates to sewage treatment area, relate in particular to a kind of waste disposal plant and sewage water treatment method thereof.
Background technology
At present, in the enterprise production process such as food, papermaking, printing and dyeing, pharmacy, chemical industry, discharge a large amount of sewage, these sewage belong to organic waste water, and this organic sewage need just can be discharged into occurring in nature through processing, can serious pollution of water environment in nature water body otherwise be directly discharged into.
In recent years, the problem of water environment pollution and body eutrophication is day by day serious.And nitrogen, phosphorus are the principal elements that causes body eutrophication.Along with the limitation standard of the raising of Public Environmental Awareness and the discharge to nitrogen, phosphorus is both at home and abroad more and more stricter, economic, the efficient organism of research and development, nitrogen, phosphorus associated treatment technology are the focuses in Water Pollution Control Engineering field always.
The mixed industrial waste water of manufacturing district is all difficult, particularly taking production of antibiotics waste water as main mixed industrial waste water more difficult.Production of antibiotics waste water is element of the first species's complexity, colourity is high, bio-toxicity is large, containing the high concentration hard-degraded organic waste water of multiple inhibitory substance, be difficult point and the focus of sewage disposal both at home and abroad at present.Such wastewater treatment is done to many Test And Research Works both at home and abroad, as adopt Fenton reagent method, photocatalytic oxidation, Ozonation and activated sludge process etc., the shortcomings such as but these technology exist that floor space is large, investment is large, processing cost is higher and wastewater treatment compliance rate is on the low side are therefore subject to larger restriction in Practical Project is promoted.Manufacturing district, Fujian Province first phase of construction adopts " acidication+MSBR+ flocculation sediment " coupling technique to process this district taking production of antibiotics waste water as main mixed industrial waste water, Sewage Plant is runed for many years practice and is shown: in the time that water inlet meets design influent quality standard, and effluent quality CODcr, NH
3what the equal energy of every pollutant emission index such as-N and TP was stable reaches country's " integrated wastewater discharge standard " (GB8978-1996) requirement of secondary standard; This art breading effect stability, anti impulsion load is stronger, and process combination is more reasonable, but can only reach the requirement of secondary discharge standard; The second stage of the project adopts " acidication+MSBR+ ozone oxidation+flocculation sediment+BAF " compounding technology processing, though can reach the requirement of first discharge standard, floor space is large, processing cost is high, operation management is complicated.
Anaerobic/anoxic/aerobic method (being AA/O method) is although that the feature of biological carbon and phosphorous removal is technique is simple, and can synchronous denitrification dephosphorizing, total residence time is short, mud is difficult for expanding, without dispensing, processing costs is low, but AA/O method exists when reaching after certain effect, and dephosphorization amount and nitric efficiency are difficult to the problem further improving.Though improvement AA/O method combines the advantage of A/O method and improvement UCT technique, before anaerobic pond, set up anaerobic/anoxic pond, the polyP bacteria that is conducive to anaerobic pond is released phosphorus and has been suppressed hyphomycetic breeding simultaneously, improve mud-water separation performance, improve operation stability and treatment effect, but exist sludge reflux amount large, increase cost of sewage disposal.
At present, be handling object to the research of AA/O method and deformation technique thereof mainly with sanitary sewage both at home and abroad, and it is less to adopt AA/O method directly to process the report of trade effluent, particularly, taking antibiotics pharmacy as the main rarely seen report of trade effluent, inversion A A/O method is directly processed taking antibiotics pharmacy as main trade effluent and is not reported.Propose to adopt " modified version inversion A A/O method+BAF+flocculation sedimentation tank " coupling process to process industrial sewage based on this inventor.
Summary of the invention
The object of the present invention is to provide a kind of organic efficient to remove denitrogenation dephosphorizing efficiency is high simultaneously, treatment effect is reliable and stable, running cost is low waste disposal plant and sewage water treatment method thereof.
For achieving the above object, the present invention adopts following technical scheme:
