Microbial agent for sewage treatment, attachment carrier of microbial agent and preparation method of microbial agent

Abstract

The invention discloses a microbial agent for sewage treatment. The microbial agent comprises, by weight, 8-10 parts of clostridium acetobutylicum, 12-16 parts of bacillus licheniformis, 16-20 parts of bacillus subtilis, 5-7 parts of lactobacillus acidophilus, 5-7 parts of methanosarcina, 3-5 parts of methanosaeta, 6-8 parts of rhodopseudomonas palustris, 4-6 parts of cellulomonas flavigena, 8-10parts of streptococcus thermophilus, 8-10 parts of alcaligenes faecalis, 3-5 parts of bacillus amyloliquefaciens, 2-4 parts of bacillus nitrosomonas, 1-3 parts of issatchenkia orientalis and 3-5 partsof streptomyces bullis. Besides, the invention further discloses an attachment carrier of the microbial agent and a preparation method of the microbial agent. The microbial agent can be effectively attached to the carrier and accordingly has better activity. The microbial agent is reasonable in strain preparation and can be effectively attached to the attachment carrier to treat sewage, and the method for sewage treatment is simple, good in treatment effect and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a microbial agent for sewage treatment, its attachment carrier and a preparation method thereof. Background technique [0002] Water is the source of human life and is irreplaceable. However, the discharge of industrial wastewater and domestic sewage into natural water bodies has caused large-scale and large-scale pollution of various water bodies. The decomposition of organic matter in the polluted water body consumes a large amount of dissolved oxygen, resulting in severe anoxic or anaerobic water bodies, which eventually leads to black and smelly river water. Black and odorous rivers are a type of water pollution. In anoxic water, anaerobic microorganisms decompose organic matter to produce a large amount of odorous gases such as methane, hydrogen sulfide, ammonia, amine and other odorous and volatile small molecule compounds, which escape from the water s...

Problems solved by technology

As for sewage treatment, currently commonly used methods include physical, chemical and biological methods. Physical and chemical methods cannot fundamentally solve the problem of black and odorous river water.

Therefore, with the improvement of environmental protection requirements and the continuous development of environmental biotechnology, bioremediation is a low-investment, high-efficiency, and convenient and flexible water pollution control technology. Bioremediation often uses microbial methods to treat polluted water bodies. Many microbial methods use a single biological bacteria to treat polluted water bodies, which makes the survival rate and activity of microbial bacteria low, and it is also difficult to restore the self-purification ability of water bodies
