Bioactive composite fermentation broth for purifying water quality by using microorganisms

Abstract

The invention provides a bioactive composite fermentation broth for purifying water quality by using microorganisms, which is also called as an enzyme active agent. The bioactive composite fermentation broth comprises the following raw material components in parts by weight: 0.8-1.2 parts of brown sugar and / or molasses, 2.5-3.5 parts of fresh pericarp and 8-12 parts of water. The raw material components are mixed and then are subjected to sealed anaerobic fermentation for more than three months to form the composite fermentation liquor with biological activity. The composite bioactive enzyme is fungus compound fermentation liquor based on the raw material components and is a natural fermentation composite biological oxidant. The enzyme active agent is short in polluted water quality bioremediation time; operation is easy and convenient, and interference to the surrounding environment is little; the cost is low and is only 30%-50% of the cost of a physical and chemical method; no secondary pollution is generated; the chance that human beings are directly exposed to the pollutants is small; pollutants can be completely removed from the environment.

Description

technical field [0001] The present invention relates to a compound fermented liquid that utilizes microorganisms to purify water—an enzyme active agent. Its main technical field is fermentation engineering; it relates to related fields: enzyme catalysis engineering, microbiology, and environmental engineering. Background technique [0002] The development trend of the food processing industry in developing countries is becoming more and more obvious. These types of industries generate large amounts of organic waste, mainly vegetables and fruits. On the one hand, improper disposal of these organic wastes and other municipal solid wastes in open dumps creates unpleasant odors and also increases pathogenic microorganisms that affect human health. On the other hand, disposing of organic waste through landfill method will generate greenhouse gases and leachate, which will affect the atmosphere and water environment to a greater extent. Organic waste and sludge in landfills even...

Problems solved by technology

However, bacteria require more investment. At the same time, because photosynthetic bacteria are photoautotrophic bacteria and do not contain nitrifying and denitrifying bacteria, the effect of removing phosphorus and nitrogen is not obvious, and the removal ratio is only cod:n:p =100:5:l, but cannot solve the problem of water body "sublimation" and eutrophication

[0018] 4. Chemical methods For slow-flowing water bodies such as lakes and rivers, when eutrophication has occurred due to a large amount of plant nutrients such as nitrogen and phosphorus being discharged into the water, the method of directly adding chemical agents to the water can be used to kill algae , and then through natural precipitation, clearing the silt layer can achieve the purpose of preventing eutrophication of the water body, but this method will add chemical reagents, which will also cause certain "contamination" effects on the water body itself

However, the method of aeration can only delay the occurrence of eutrophication in the water body, and cannot fundamentally solve the "red tide" phenomenon caused by eutrophication in the water body
