Problems solved by technology

This method of adding inorganic phosphorus sources to treat sewage still has the following disadvantages: traditional sewage treatment microorganisms have low absorption efficiency of phosphate ions, and most of the phosphorus sources are wasted and precipitated; the amount of inorganic phosphorus used is large, and the cost is wasted; It is inconvenient to carry and store the source, and the on-site labor intensity is high; resulting in excessive ammonia nitrogen in the effluent, etc.
If urea is used alone, the volatilization loss is large, and the utilization rate is only about 30%.
[0005] In summary, in the existing sewage treatment methods, the use of phosphorus and nitrogen is large, the utilization rate is low, which is not conducive to the absorption and utilization of microorganisms, and the sewage treatment capacity is limited

Abstract

The invention discloses a sewage treatment method for biologically active phosphorus and nitrogen, comprising the following steps: S1. preparing biologically active phosphorus: reacting alcohols with 2-15 C atoms and phosphate ions to form organic phosphates; S2. preparing Biologically active nitrogen: nitro nitrogen and amino nitrogen are mixed by mass percentages of 23~68% and 32~77% respectively; S3. The biologically active phosphorus obtained by step S1 and the biologically active nitrogen obtained by step S2 are by mass ratio 1: 3~8 are mixed and added to the sewage, and then the surfactant and the biological growth promoter are added in sequence, and aeration is carried out to obtain the treated sewage. The method of the invention can improve the absorption and utilization rate of phosphorus and nitrogen by the microbial cells of sewage, and at the same time, the biological promoting substances and surfactants are added, which can further improve the absorption capacity of the microbial cells and effectively improve the tolerance of the microbial cells , increase community diversity and activity, increase community diversity and activity, and improve the ability of microorganisms to degrade sewage organic matter.

Description

technical field [0001] The invention belongs to the technical field of industrial sewage treatment, and more specifically relates to a sewage treatment method for biologically active phosphorus and nitrogen. Background technique [0002] The content of phosphorus and nitrogen in industrial sewage is low, which is not conducive to the treatment of sewage by microorganisms. At present, the traditional sewage treatment is to add a phosphorus source of nutrients to the sewage to increase the uptake of phosphorus by microorganisms and improve the sewage treatment capacity. Among them, inorganic phosphorus is mainly used as the phosphorus source, and phosphate fertilizer, potassium dihydrogen phosphate, sodium, trisodium phosphate, etc. are usually used. This method of adding inorganic phosphorus sources to treat sewage still has the following disadvantages: traditional sewage treatment microorganisms have low absorption efficiency of phosphate ions, and most of the phosphorus so...
