Wine production waste water treatment agent and waste water treatment method

Abstract

The invention belongs to the field of food enterprise waste water treatment and relates to a wine production waste water treatment agent and a wine production waste water treatment method. The wine production waste water treatment agent comprises, by weight, a physical water purification agent comprising 1-5 parts of active carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide, composite microbe inocula comprising 0.02-0.1 parts of bacillus coagulans powder, 0.05-0.2 parts of marinobacter powder, 0.05-0.2 parts of bacillus megaterium powder and 0.04-0.2 parts of paracoccus denitrificans powder, and an enzyme preparation comprising 0.05-0.1 parts of glucose oxidase, 0.04-0.09 parts of pectase and 0.01-0.06 parts of papain. The wine production waste water treatment agent and the wine production waste water treatment method realize hydrolysis of complex, difficult-degraded and large granule organic matters into easy-degraded simple organic matters and greatly reduce SS content of waste water. The treated waste water has high waste water BOD and COD clearance and satisfies discharge standards.

Description

technical field [0001] The invention belongs to the field of waste water treatment of food enterprises, and in particular relates to a treatment agent for wine production waste water, and also relates to the above-mentioned wine production waste water treatment method. Background technique [0002] With the development of the economy and the improvement of people's living standards, wine consumption has become a fashion, and the wine industry has developed rapidly. Products, accompanied by a large increase in production wastewater, causing surface water and even groundwater pollution, especially causing eutrophication of water bodies, destroying the self-purification ability of water bodies, resulting in low water reuse rates, depletion of water resources, and water resources The rational and effective development and use of fresh water resources is directly related to the sustainable development of the world, and the reasonable and effective treatment of wine production was...

AI Technical Summary

Problems solved by technology

At present, domestic wine production wastewater is mostly treated with multi-stage aerobic, SBR, and CASS processes, but the results are not satisfactory. Although multi-stage aerobic treatment of wine production wastewater can meet the discharge standards, it requires dilution water and water distribution, resulting in large sludge production and operating costs. High, and it is difficult to meet the standard stably due to the production cycle, and it is necessary to increase the advanced treatment process, thereby increasing investment and operating costs

Compared with SBR, CASS has a certain degree of advancement. It has a better treatment effect for wastewater with COD less than 2000 mg per liter, but it is not easy to reach the standard stably for wine production wastewater with high concentration and high treatment requirements.
