Guangdong industrial wastewater treatment Alcohol - Alcohol Wastewater Treatment

Production of alcohol mainly starch feedstock (corn, dry matter, cassava) raw materials such as molasses combination of the production process alcohol wastewater discharged contains protein, fat and other ingredients can be used as a useful fodder for reuse. Alcohol wastewater is also a high concentration of organic wastewater, has a high pollution load. The main source of the alcohol plant wastewater discharge of waste and equipment, pipelines and other washing water, ground water rinse. Drainage mainly contains starch, protein, yeast residues, hops residue washed with a small amount of alcohol and alkali, non-toxic organic wastewater. Questions about how alcohol plant sewage treatment, in fact, there are many ways, alcohol bad though non-toxic, but high pollution load into the acid. According to different raw materials for ethanol production, the distillers of utilization and treatment using different methods. Up Environmental Protection Technology Co., Ltd. After years of experience in waste water treatment industry to explain an effective treatment. Alcohol wastewater treatment processes used 1. Efficient full hybrid anaerobic sludge tank (EASB) anaerobic reactor with steel, its shape is structurally similar to the third generation of the anaerobic reactor EGSB and IC, can withstand high concentrations of suspended solids (SS), are three generations of anaerobic reactor EGSB and IC does not have the characteristics of high temperature fermentation, volumetric loading up 7.0kgCOD / (m3.d), 2-3 times higher than the traditional full-residue anaerobic fermentation process, COD removal efficiency of 90%. 2.UASB + contact oxidation anoxic upflow anaerobic sludge reactor (UASB) technology flows upward at home and abroad has become one of the mainstream technology of anaerobic treatment, without a carrier in UASB, the sewage from the bottom even enter, granular sludge (floc) at the rise of the water and the bubble effect in suspension. The lower part of the reactor is higher concentrations of sludge bed, the upper portion is a lower concentration of suspended sludge layer, this organic material into methane and carbon dioxide gas. In the upper part of the reactor has three-phase separator, degassing and can precipitate the sludge back to the reactor. Higher COD load UASB reactor sludge concentrations up to 100-150g / L, COD removal efficiency and therefore higher than the average of the anaerobic reactor three times, up to 80% to 95%. 3. Biological contact oxidation method is a biofilm, which belongs to aerobic biological treatment process. The system consists of the cell body, filler, aeration equipment and other components. Aerobic Biological bacterial and fungi microorganisms and other metazoan a class of miniature animals on the packing support growth and reproduction of microbes take organic matter in sewage as nutrients, decomposition of organic matter in sewage adsorption, microbial metabolism continues to maintain active so that the water will be purified. 4.IC + A / O IC reactor that is expanded granular sludge bed reactor, is developed on the basis of UASB reactor on the third generation of anaerobic bioreactor, effluent recycle through recycled, greatly improving the sewage The upflow velocity, granular sludge reactor is always in an expanded state, to strengthen contacts and mass transfer between water and microbes get high removal efficiency, height of the reactor up to 16-25m.
