Food industrial raw material widely, there are many different kinds of products, the discharge of waste water, the water quality difference is very big. The main pollutants in the waste water are:
(1) floating solids in the wastewater, such as tea, fruit, meat, poultry feathers, etc.;
(2) the suspended substance in waste water with oil, protein, starch, colloidal substance, etc.;
(3) dissolved in wastewater of acid, alkali, salt, sugar, etc.;
(4) raw material entrainment of sediment and other organic matter, etc.;
(5) pathogens poison, etc.
The characteristics of the food industry wastewater is organic material high suspended solids content, easy to corruption, there is no greater toxicity. The harm is mainly the eutrophication of water bodies, so that the cause of aquatic animals and fish, prompted the subaqueous sedimentary organic matter production stink, deteriorating water quality, the environmental pollution. Jason has developed UASB technology, can very good high concentration food wastewater treatment, solving the problem of food waste water pollution.
