Vinegar production wastewater treating agent and wastewater treatment method

Abstract

The invention belongs to the field of food enterprises' wastewater treatment, particularly relates to a vinegar production enterprises' wastewater treating agent and further relates to a vinegar production wastewater treatment method. The vinegar production wastewater treating agent is prepared from, by weight, a physical water purifying agent including 1-5 parts of activated carbon, 1-5 parts of organic modified zeolite and 1-5 parts of polyacrylamide, a compound microbial agent including 0.02-0.1 part of konjac acidovorax powder, 0.05-0.2 part of sulfate reducing bacterium powder, 0.05-0.2 part of lysine bacillus powder and 0.04-0.2 part of Moraxella powder, and an enzyme preparation including 0.05-0.1 part of xylanase, 0.04-0.09 part of Streptomyces protease and 0.01-0.06 part of acid protease. By the adoption of the wastewater treating agent and the wastewater treatment method, complex large-particle organic matter difficult to degrade is hydrolyzed into simple organic matter easy to degrade, the SS content in wastewater is greatly reduced, the BOD and COD removal rate of the treated wastewater is high, and the prescribed discharge standards are reached.

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 vinegar production waste water, and also relates to the above-mentioned method for treating vinegar production waste water. Background technique [0002] Vinegar production is a traditional industry in my country, and its wastewater is a kind of organic wastewater with high organic matter concentration, high chroma, and ultra-high ammonia nitrogen. The current treatment technology still has certain limitations. Vinegar wastewater is characterized by high organic matter concentration, high ammonia nitrogen concentration, and high chroma. Direct discharge will cause great harm to the environment. Organic matter and ammonia nitrogen are the main pollution indicators for water pollution control in my country. The pollution caused by these pollutants Water pollution, environmental pollution and threats to human health are relati...

Vinegar wastewater is characterized by high organic matter concentration, high ammonia nitrogen concentration, and high chroma. Direct discharge will cause great harm to the environment. Organic matter and ammonia nitrogen are the main pollution indicators for water pollution control in my country. The pollution caused by these pollutants Water pollution, environmental pollution and threats to human health are relatively serious, and due to the small scale of the vinegar production industry in the past and the special geographical environment, there is insufficient understanding of the characteristics and treatment technologies of its production wastewater. There are certain defects, the discharge of production wastewater is also increasing, and the impact on water pollution is becoming more and more serious.

Especially the high ammonia nitrogen in the wastewater, it is difficult to completely dispose of it by simple treatment technology, so it is of great practical significance to carry out the research and engineering practice of vinegar production wastewater treatment technology

[0003] The facultative oxygen adjustment tank has the function of regulating water quality and water quantity and hydrolysis, and can degrade some macromolecular organic matter, creating conditions for subsequent biological treatment. The biggest advantage of the AB method is that each treatment stage in the process has its own dominant microorganisms. Therefore, the organic matter The degradation ability is particularly strong and the treatment efficiency is high, but the removal of ammonia nitrogen by this process cannot meet the emission requirements of environmental protection
