A microbial preparation for purifying and improving water quality

Abstract

The invention discloses a microbial preparation for purifying water and improving water quality. The microbial preparation comprises a microbial nutrient solution and a water purifying agent, wherein the microbial nutrient solution is obtained by uniformly stirring 15-25 parts of molasses, 35-45 parts of glucose, 12-18 parts of sucrose, 15-25 parts of starch, 15-25 parts of chitosan, 15-25 parts of amino acid fertilizer water paste and 100-140 parts of deionized water, adding 15-25 parts of EM original liquid and fermenting for 8-12 days in an incubator; the weight ratio of the water purifying agent to the microbial nutrient solution is 1:8-1:12. According to the microbial preparation, the water can be purified, the quality of sludge at the bottom of the water is improved, the pollution of a water body is reduced, the nutrition of the water body is improved, breeding and growing of harmful germs are inhibited, the body immunity, the disease prevention and the disease resistance of aquaculture animals are improved, growth development of aquatic animals is promoted, and the yield and the quality of aquaculture organisms are improved.

Description

technical field [0001] The invention relates to a microbial preparation for purifying and improving water quality, which belongs to the field of environmental protection. Background technique [0002] The conventional method of water purification is through flocculation, precipitation, filtration and chemical treatment. In this method, attapulgite, diatomaceous earth, zeolite powder, iron salt, aluminum salt and polyacrylamide are commonly used for water purification. Studies have shown that attapulgite has excellent adsorption properties, can absorb ammonia ions in fish ponds, prevent water pollution, and prevent odor. In sewage treatment, attapulgite can be regenerated, it consumes less energy, and is very beneficial to environmental protection. Diatomite has a neutral pH value, non-toxicity, good suspension performance, strong adsorption performance, light bulk density, and oil absorption rate of up to 115%. Improve the survival rate of aquatic products. Natural zeolit...

Problems solved by technology

[0005] Existing water purifiers have a single function. After purifying the water, it is easy to cause harmful substances to remain in the water. It is difficult to purify the sludge at the bottom of the water. Harmful microorganisms in the water multiply in large numbers and do not really play a role in purifying the water.
