The Process Flow Design of the Wastewater Treatment of Donkey-hide Gelatin Factory
Abstract:In the donkey-hide gelatin production process,the sewage discharges contaminants basically include more complex ingredients such as hair,shiver which are insoluble substances and solubility colloidal proteins like organic dirt.These contaminants are with high concentration and good Biodegradability.Untreated emissions of the sewage discharges contaminants will generate serious environmental pollution,sewage discharges in the donkey-hide gelatin production process is indispensable.From sewage discharges water quality analysis of the donkey-hide gelatin production process,it is clear that the sewage in this process have the basic of high concentration organic wastewater with good Biodegradability.Judging from the investment,efficient biochemical method is given priority to in technology choice,and the SBR method has been choose in the secondary process.
Key words:Wastewater of donkey-hide gelatin factory;sequencing batch reactor activated sludge process;hochprozentig organic sewage;biochemical process
