Abstract
The invention relates to a module processing method for distributed slaughter wastewater. The method is particularly suitable for treatment of small distributed slaughter wastewater. Combined modules are selected and connected in series; an on-line monitor is connected at the front end of the combine module. The combined module comprises a materialized module-coagulation air flotation and drug hydrolysis; a biochemistry module-anaerobic biofilter and a constant water level batch activated sludge reactor, a deep processing module-reverse osmosis. Influent water quality can be detected according to on-line monitor, when a COD concentration is 500-1,500 mg/L, a gas-water ratio of the coagulation air flotation module is adjusted to 3:1; a temperature of the anaerobic biofilter is controlled at 20-25 DEG C; sludge load rate is selected at 0.10 kg/(kg.d); a temperature of CWSBR is controlled at 15-20 DEG C; and dissolved oxygen is controlled at 3-4 mg/L. The module processing method can not only improve effluent quality of the slaughter wastewater, is simple in management, can realize automation and modularization, is small in floor area and low in operation cost.
Description
Technical field
The present invention relates to technical field of waste water processing, definite say a kind of distributing slaughterhouse wastewater resume module method, be specially adapted to the processing of small-sized distributing slaughterhouse wastewater.
Background technology
Along with the fast development of meat processing industry, in trade effluent, butcher and ratio that meat processing waste water is shared rises year by year, the generation of such waste water with butcher and the quantity of meat processing enterprise presents proportional relation.According to data, nationwide above meat in 2012 is butchered and meat product processing enterprise reaches 3696, and wherein animals and poultry slaughtering processing enterprise is not 2076, and meat product is processed as 1620, and two kinds of patterns of enterprises are than being 56:44.In addition, canned meat manufacturing concern is 91.Bank of animals and poultry slaughtering and meat, the above enterprise of process scale sum increases by 600 than last year, wherein butchers and increases by 277, and goods processing increases 323Jia, canned meat manufacturing concern and increases by 3.It is predicted, the coming five years China Meat Industry keeps 12% ~ 15% average annual growth rate development, illustrated that China's Meat Industry is fast-growth, also shown that China's meat processing industry wastewater discharge also increases year by year simultaneously, the advanced treatment of meat processing waste water is extremely urgent.
Most cities, nationwide have been realized the concentrated fixed point of livestock and poultry and have been massacred, but in the vast Rural areas of Liaohe River Basin, the middle-size and small-size meat processing of part enterprise gives full play to intrinsic advantage, for rural economic development injects fresh and alive vitality.But simultaneously in these small-sized distributing enterprise process of manufacture, produce a large amount of slaughterhouse wastewaters; slaughterhouse wastewater belongs to high concentrated organic wastewater; contain impurity, Pollutant levels are higher; intractability is larger; in addition Some Enterprises, because improvement lacks of capital and Rural Water Environment is protected to the thin of consciousness, is disposed of sewage without direct discharge up to standard, with runoff, flows into water body; rural area physical environment is threatened greatly, become one of factor of rural rivers lake water quality deterioration.Small-sized distributing meat processing wastewater treatment becomes China's water treatment field problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of a kind of small-sized slaughterhouse wastewater standardized module composite processing system-distributing slaughterhouse wastewater resume module method, according to the water quality of small-sized distributing slaughterhouse wastewater, adopt three kinds of composite modules, i.e. materialization module, biochemical module, advanced treatment module.
