Abstract

The invention relates to a complex microbial agent for quickly treating black and odorous water in towns. The compound microbial agent is prepared from, by weight, 4-18 parts of a bacillus subtilis complex flora, 2-15 parts of a pseudomonas complex flora, 2-10 parts of a photosynthetic bacteria complex flora, 2-10 parts of a Gordonia complex flora, 2-10 parts of nutrients, 1-5 parts of hydrolase and 10-35 parts of a solid carrier. By means of the complex microbial agent, ammonia nitrogen, COD and other indexes of the black and odorous water can be quickly reduced by degradation, the high degradation efficiency can still be kept under the condition of low dissolved oxygen, and the problem of low degradation efficiency of existing complex microbial agents under the condition of low dissolvedoxygen is effectively solved.

Description

Technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to a composite bacterial agent for quickly treating black and odorous water bodies in cities and towns. Background technique [0002] In recent years, with the rapid development of our country’s economy, people’s living standards have gradually improved, but the ensuing environmental problems have become increasingly prominent. Among them, the black and odor of rivers and lakes is a major problem. Most of the industrial wastewater and domestic sewage are directly discharged into rivers or lakes without effective treatment, resulting in the accumulation of a large amount of organic matter in the water body and deposits at the bottom of the river or lake. The aerobic decomposition of organic matter in the water leads to an increase in the rate of oxygen consumption. The water body lacks oxygen and anaerobic microorganisms multiply to degrade the organic matter in the wat...
