With the rapid development of industry, the variety and quantity of waste water are rapidly increased, the pollution to water is becoming wide and serious, and the health and safety of human beings are threatened. Since the composition of industrial waste water is more complex and some are toxic, it is also more important that industrial waste water treatment is more difficult than municipal waste water treatment. The alcohol wastewater is organic wastewater with high concentration, high temperature and high suspended matter, and the treatment technology starts earlier and develops faster.
The waste residue in the waste liquid contains crude fibers such as crushed cassava skin, rhizomes and the like, and the substances are insoluble COD in the waste water; cellulose and hemicellulose in cassava are polysaccharide substances, cannot be used as a carbon source of yeast in alcohol fermentation, and remain in waste liquid to be expressed as soluble COD; silt impurities of inorganic ash. These substances increase the difficulty of wastewater treatment.
The prior patent technologies mainly focus on the process of flocculation adsorption and precipitation, for example, patent numbers CN201210483774 and CN201510220252 are all based on flocculation adsorption of CODcr, so as to improve the removal efficiency of CODcr. However, the removal effect of these treatments is not very significant, resulting in a high subsequent biochemical load. Therefore, the market at present needs a wastewater treatment agent which not only can realize flocculation, but also can efficiently remove CODcr.
