Abstract

The invention discloses a microbial agent for treating high-salt industrial wastewater and a preparation method of the microbial agent, and belongs to the technical field of wastewater treatment. The microbial agent comprises a polyacrylamide outer layer and a microbial purification core, and the outer wall of the microbial purification core is wrapped with a slow-release capsule layer. The microbial purification core is prepared from the following components in percentage by mass: 20 to 40 percent of composite treatment bacteria porous particles, 10 to 20 percent of bacillus licheniformis porous particles, 10 to 20 percent of Micrococcus lylae porous particles, 10 to 20 percent of Citrobacter freundii porous particles, 10 to 20 percent of bacillus subtilis porous particles and 10 to 20 percent of bacillus amyloliquefaciens porous particles. Through the porous filler particles, the dispersion of bacteria is facilitated, the treatment effect of the bacteria is effectively improved, and the treatment speed of the high-salinity wastewater is effectively improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, more specifically, to a microbial agent for treating high-salt industrial wastewater and a preparation method thereof. Background technique [0002] High-salt wastewater refers to discharged wastewater from domestic sewage and industrial wastewater with a total salt content greater than 1%, containing relatively high inorganic ions, and also organic gases such as glycerin and medium and low carbon chains. Due to its complex and diverse components, the salt content High, it has a strong inhibitory effect on microbial growth, so the wastewater treatment technology is much more difficult than ordinary sewage treatment. [0003] Coal chemical industry, petroleum, printing and dyeing chemical industry are the major producers of high-chloride salt wastewater in my country, followed by pharmaceuticals, including human and animal biopharmaceuticals and pesticide manufacturing, which use a la...
