Description
Technical field
The present invention relates to the treatment technology of high concentrated organic wastewater, particularly relate to a kind of novel treatment equipment of percolate.
Background technology
Percolate is the high concentrated organic wastewater of a kind of complicated component that rubbish produces in landfill process, be mainly derived from that precipitation infiltrates, organic substance decomposing and rubbish itself interior moisture etc.COD (6000-15000mg/L) containing high density in typical percolate, ammonia nitrogen (500-3000mg/L), in addition containing a large amount of microorganisms, heavy metal, inorganic salt and hazardous and noxious substances etc., directly discharged if do not processed and very easily cause underground water, surface water pollution, and then jeopardize HUMAN HEALTH.
The character of percolate selects the Main Basis for the treatment of process, and at present, the method for treating garbage percolation liquid adopted both at home and abroad mainly contains physico-chemical process, biological process and land treatment systems method.Physico-chemical process comprises the methods such as coagulation, stripping, charcoal absorption, ion-exchange, membrane sepn, the methods such as biological process has activated sludge process, biological contact oxidation process, A/O method, SBR method etc., and land treatment systems then mainly comprises slow rate, fast diafiltration, artificial swamp, recharge.Because percolate is different from general sanitary sewage, its biodegradability is poor, if adopt separately a kind for the treatment of process to be difficult to reach processing requirements, and processing cost is very high, therefore, in actual applications, processing cost is reduced, the normal combination process needing multiple method for improving treatment effect.
Country in 2008 has put into effect " household refuse landfill sites Environmental capacity standard " GB16889-2008 and instead of original GB16889-1997, water pollutions emission concentration limits is had higher requirement, traditional biochemistry combination process is more difficult reaches effluent quality requirement, therefore, existing treatment process more adopts the combination process of biochemistry+reverse osmosis.Conventional reverse osmosis membrane technology adopts board-like, rolling, spiral wound and hollow fiber form reverse osmosis unit, these devices mainly for seawater, drink water purification, and percolate is as the sewage of the complicated component of typical high density, high salinity, high conductivity, if directly utilize said apparatus to occur the fouling of film, dirty stifled, the frequent cleaning even shortcoming of membrane damage.
Summary of the invention
The object of the present invention is to provide a kind of process, the device for treating leachate that treatment effect is good, to increase the rate of recovery of landfill leachate treatment to greatest extent.
