Abstract

The invention discloses a microbial agent for reducing sludge. The microbial agent 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, 5-7 parts of lactobacillus acidophilus, 5-7 parts of methanosarcina, 3-5 parts of methanosaeta, 6-8 parts of rhodopseudomonas palustris, 4-6 partsof cellulomonas flavigena, 8-10 parts 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 parts of streptomyces oxalis. The invention also discloses a carrier of the microbial agent for reducing sludge and a preparation method thereof. The carrier is capable of effectively attaching microorganisms and endowing microorganisms with higher activity. Strains are reasonably prepared in the microbial agent disclosed by the invention; the microbial agent is attachedto the carrier for treating sewage; when the method is used for treating sewage, the operation is simple, the treatment effect is excellent and sludge deposition is less; the method 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...
