Enhanced nitrogen and phosphor removing method using composite microbes to effectively process high concentration organic wastewater

Abstract

The invention relates to an enhanced nitrogen and phosphorus removal method for compound microorganisms to efficiently treat high-concentration organic wastewater. The wastewater first enters the energy release area, and the water from the overflow weir in the energy release area is divided into two paths, one path enters the strict anaerobic area, and the other path enters the biological Selection area; in the biological selection area, the sludge returned from the strict anaerobic area and the influent are fully mixed, and then enter the complex microbial reaction area; in the complex microbial reaction area, short-range nitrification and denitrification, anaerobic ammonium oxidation, and the whole process Autotrophic denitrification, simultaneous nitrification and denitrification and other processes, so as to achieve the purpose of denitrification; the waste water enters the mud-water separation area after passing through the compound microbial reaction area, and the clear water separated in the mud-water separation area enters the phosphorus removal area for phosphorus removal, and finally makes the waste water reach Discharge standards or pre-treatment standards for reused water. This method is a new breakthrough to the original traditional sewage treatment process. In the environment of low dissolved oxygen, high sludge concentration and high removal rate make the energy consumption of wastewater treatment greatly reduced.

Description

technical field [0001] The invention relates to an enhanced denitrification and dephosphorization method for efficiently treating high-concentration organic wastewater by complex microorganisms. Background technique [0002] At present, the types and discharges of domestic sewage and industrial wastewater are increasing, and the composition is more complex, which contains many refractory organic substances, such as dyes, phenols, phenols, pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, nitroaromatic compounds, alkanes, etc. Base benzene sulfonic acid and humic acid etc. Most of these refractory organic substances are artificially synthesized organic substances, and most of them are toxic organic pollutants. Distortion, carcinogenesis) and toxicity, and some substances have endocrine disrupting effects. Compared with natural organic matter in water bodies, they are more harmful to human health. At the same time, synthetic compounds are often adsorb...

Problems solved by technology

[0015] In traditional nitrification and denitrification denitrification technology, nitrification and denitrification are still carried out in two independent or separated reactors with different DO concentrations, or in the same one that creates alternate anoxic and aerobic environments in time or space. It is carried out in a reactor, one process is divided into two systems, the condition control is complex, the two are difficult to unify in time and space, the denitrification effect is poor, the equipment is huge, and the investment is high
