Problems solved by technology

[0002] At present, the treatment of industrial sewage has attracted more and more attention in the field of environmental protection. In the process of sewage treatment, unstable water quality is still a relatively common phenomenon. However, simple microbial decomposition is slow and not easy to achieve quick results. Biological treatment system There are common problems such as easy expansion of sludge and poor impact resistance to water quality and quantity.

Abstract

The invention discloses an enzyme preparation for treating industrial sewage. The enzyme preparation comprises compound enzymes, a carrier, organic acid, polyethylenimine, inorganic salt, yeast extract and water, wherein the compound enzymes comprise protease, cellulase, oxido-reductase, pectinase, dehydrogenase and lysozyme. After the enzyme preparation is used, the average removal rate of COD (chemical oxygen demand) is 1.46 times that before the use of the enzyme preparation, the average ammonia nitrogen removal rate after the use of the enzyme preparation is 1.48 times that before the use of the enzyme preparation, sludge residues are about 0.56 time that of a conventional sewage treatment system, and high sludge sedimentation performance is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an enzyme preparation for treating industrial sewage. Background technique [0002] At present, the treatment of industrial sewage has attracted more and more attention in the field of environmental protection. In the process of sewage treatment, unstable water quality is still a relatively common phenomenon. However, simple microbial decomposition is slow and not easy to achieve quick results. Biological treatment system There are common problems such as easy expansion of sludge and poor impact resistance to water quality and quantity. The level of system treatment efficiency is closely related to the quality of microbial activity. In the process of biological treatment of sewage, a large amount of excess sludge will inevitably be produced. The current incineration treatment not only requires high costs, but also produces toxic gases during incineration to pollute the e...
