Abstract

The invention relates to compound liquid for enhancing sewage biological treatment. The compound liquid mainly strengthens the effect of a coenzyme through a carrier, thereby enhancing the microbial activity of sludge zoogloea and improving the structure of the zoogloea for enhancing the sewage biological treatment capacity at the same time of catalytically decomposing organic pollutants. The compound liquid is characterized by convenient use, small using amount and high efficient and rapid enhancing capacity, thereby being applicable to a biological treatment unit of a sewage treatment plant.

Description

technical field [0001] The invention discloses a composite liquid agent with a good strengthening effect on sewage biological treatment, belonging to the technical field of water treatment. Background technique [0002] Chitosan is the deacetylation product of chitin, which has excellent biocompatibility and biodegradability, and has many application values ​​in medicine, environmental protection and food. In water treatment, chitosan can usually be used as a good adsorbent, flocculant, heavy metal ion chelating agent and sludge conditioner. With the deepening of research in recent years, chitosan has also shown unique advantages in strengthening biological treatment. [0003] Ribonucleic acid in nucleic acid has the function of coenzyme, but the function of independent nucleic acid is not easy to fully exert. Chitosan molecules contain a large number of hydroxyl groups and amino groups, which can form hydrogen bonds, electrostatic interactions and hydrophobic interactions...
