A microbial agent for sludge reduction, its carrier and its preparation method

Abstract

The invention discloses a microbial bacterial agent for reducing sludge, which comprises the following components in parts by weight: 8-10 parts of Clostridium acetobutylicum, 12-16 parts of Bacillus licheniformis, 16-20 parts of Bacillus subtilis, acidophilus 5-7 parts of Lactobacillus, 5-7 parts of Methanosarcina, 3-5 parts of M. 8-10 parts of Cocci, 8-10 parts of Alcaligenes faecalis, 3-5 parts of Bacillus amyloliquefaciens, 2-4 parts of Nitrosomonas, 1-3 parts of Issaccharomyces orientalis and 3-5 parts of Streptomyces bullus ; At the same time, it discloses a carrier of microbial agent for sludge reduction and its preparation method. The carrier can effectively attach microorganisms to make the microorganisms have better activity. The strains in the microbial bacterial agent of the present invention are reasonably prepared, and are attached to the carrier for sewage treatment. The sewage treatment using this method has the advantages of simple method, good treatment effect and less sludge deposition, and is 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 reducing sludge, its carrier and a preparation method of the carrier. 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 surfac...
