Denitrification and algae-removing micro-biological bacterium agent and preparation method thereof

Abstract

The invention provides a denitrification and algae-removing micro-biological bacterium agent and a preparation method thereof. The denitrification and algae-removing micro-biological bacterium agent provided by the invention is prepared from nitrifying bacteria, nitrite bacteria, denitrifying bacteria, algicidal bacteria and photosynthetic bacteria; the content of the total viable count is not lower than 1.0*10<10>cfu/g. The content of the nitrifying bacteria and the nitrite bacteria accounts for 20 to 30 percent of the total viable count; the content of the denitrifying bacteria accounts for20 to 30 percent of the total viable count; the content of the algicidal bacteria accounts for 30 to 50 percent of the total viable count; the content of the photosynthetic bacteria accounts for 5 to10 percent of the total viable count. The denitrification and algae-removing micro-biological bacterium agent is prepared by mixing various microorganisms according to different ratios and has high viable count; the denitrification and algae-removing micro-biological bacterium agent can be used for biological remediation of a lake and reservoir water body and purification of a eutrophic culture water body and is especially suitable for treating water of a high-algae and high-ammonia-nitrogen micro-polluted water source; the removing effect on pollutants is remarkably better than the removing effect of a single strain; the denitrification and algae-removing micro-biological bacterium agent has the advantages of strong environmental adaptability, no secondary risks, high denitrification andalgae-removing efficiency and the like and belongs to an environment-friendly type micro-biological bacterium agent.

Description

technical field [0001] The invention belongs to the field of bioremediation of micro-polluted water with high algae and high ammonia nitrogen, and specifically relates to a microbial bacterial agent for denitrification and algae removal, and at the same time relates to a preparation method of the microbial bacterial agent for denitrification and algae removal. Background technique [0002] With the rapid development of my country's social economy, urban and rural drinking water sources, mainly lakes and reservoirs, are generally polluted to varying degrees. In 2016, among the 108 lakes and reservoirs monitoring nutritional status across the country, there were 20 mildly eutrophic lakes and 5 moderately eutrophic lakes and lakes, among which Taihu Lake and Chaohu Lake were mildly eutrophic and Grade IV water quality, and Dianchi Lake was moderately eutrophic. Nutrient V water quality. [0003] Conventional drinking water treatment processes cannot remove algae organic matter...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems existing in the existing high-algae, high-ammonia-nitrogen, and micro-polluted water source water treatment technology, and to provide a denitrification method that can control algae biomass and reduce water ammonia nitrogen in a short period of time, and has good social and economic benefits.
