Abstract

The invention provides a microbial agent for treating sludge of a sewage plant. The microbial agent is prepared from the following components in parts by weight: 50-60 parts of clostridium thermophile, 25-30 parts of pseudomonas denitrificans, 25-30 parts of rhodospirillum rubrum, 15-20 parts of denitrifying bacteria and 15-20 parts of saccharomycetes through strain activation, triangular flask culture medium preparation, culture and fermentation. The microbial agent disclosed by the invention is easy to obtain and can efficiently treat sludge of a sewage plant.

Description

technical field [0001] The invention belongs to the technical field of sewage plant sludge treatment, and in particular relates to a microbial agent for treating sewage plant sludge and a preparation method thereof. Background technique [0002] Sludge is a by-product of sewage treatment plants. It is a heterogeneous body composed of organic matter, bacteria, pathogens, inorganic particles, colloids, heavy metals, etc. If it is not treated effectively, it will easily cause secondary pollution to groundwater, soil, etc. , a direct threat to environmental safety and public health. [0003] There are three main methods of sludge treatment: [0004] 1 Methods of sludge stabilization treatment [0005] The mixed sludge from the primary sedimentation tank and secondary sedimentation tank (residual activated sludge or biological filter sludge) of sewage treatment plants usually contains 60% to 80% organic matter, such as carbohydrates, fats, proteins, and also contains a large am...
