Environmental Protection Alcohol Wastewater Treatment Ethanol Complete Equipment
The treatment of spent wash of cassava alcohol is mainly based on the whole mash fermentation process, which can be converted into the biomass energy at the greatest extent. First of all, the spent wash from the workshop enters the sedimentation channel to remove the bulk mechanical impurities, the sand and stone are cleaned regularly by handwork ; And then enter into the mash fluid regulation pool, and then use the centrifugal pump for conveying and for heat exchange cooling in the spiral plate heat exchanger, then for anaerobic fermentation in the fully mixed type anaerobic reactor (fermentation temperature is about 58 ℃), depending on the action of high temperature anaerobic microorganisms, organic matter is degraded to CH4 and CO2. After reaction in the fully mixed type anaerobic reactor, digestive liquid enters into the sludge thickener, concentrated sludge enters into the sludge pool, and pumped to the belt thickener press filter for concentration and dehydration processing, mud cake is conveyed to the sludge storage area by belt conveyor; The filtrate enters into the air flotation machine to further remove SS in the waste water, and then it is pumped to the UASB reactor by sewage pump to be mixed with the anaerobic sludge in the lower sludge bed. The organic matter is further degraded into CH4 and CO2 by the action of medium-temperature anaerobic microorganisms, so as to purify the water quality. The upper part of UASB is equipped with a three-phase separator. Waste water, methane and sludge flow up to the three-phase separator to complete solid, liquid and gas separation, and discharge the biogas to the gas tank and the biogas utilization system; The sludge returns to the lower sludge bed, and the effluent enters into the SBR treatment unit. After anaerobic and aerobic treatment, the wastewater can reach the specified discharge standards.
