Abstract

The invention provides a compound bacterial agent for purifying a black and odorous water body and a preparation method thereof. The compound bacterial agent comprises the following components: actinomycetes, bacillus subtilis, nitrifying bacteria, lactic acid bacteria, candida utilis and pseudomonas aeruginosa in a weight ratio of 2:2:2:1:1:1. The invention has the following advantages: the COD content, ammonia nitrogen content and phosphate salt in the black and odorous water body can be effectively reduced, and the odor of the black and odorous water body can be eliminated; and meanwhile, by adding the ammonia nitrogen removal strain, the transparency of the water body can be gradually improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment and purification, and in particular relates to a compound bacterial agent for purifying black and odorous water and a preparation method thereof. Background technique [0002] In recent years, the phenomenon of black and smelly water has become more and more serious. Black and smelly water is an extreme manifestation of water organic pollution. The mechanism of black and smelly water is basically the same, which is caused by the lack of oxygen in the water and the corruption of organic matter. Specifically, when a large amount of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed, turning the water body into an anoxic state, causing a large number of anaerobic bacteria to multiply, organic matter decay, decomposition, fermentation , making the water black and foul. ...
