Problems solved by technology

[0003] In the waste water with high concentration and small water volume, the concentration of harmful substances is high. Due to the small water volume and high concentration of pollutants, it is difficult to adopt biological treatment
The hazards of high-concentration and small-volume sewage: First, aerobic hazards: due to biodegradation, high-concentration organic wastewater will make the receiving water anoxic or even anaerobic, and most aquatic organisms will die, resulting in stench, deterioration of water quality and surroundings
The second is sensory pollution: high-concentration organic wastewater not only makes the water lose its use value, but also seriously affects the normal life of people near the water
The third is toxicity hazards: ultra-high concentration organic wastewater contains a large amount of toxic organic substances, which will continue to accumulate and store in natural environments such as water bodies and soils, and finally enter the human body, endangering human health
[0004] Therefore, there is no effective biological method for treating waste water with high concentration and small water volume: waste water from waste transfer stations, a small amount of leachate from landfills, waste water from animal farms, and waste water from catering and food processing.

Abstract

The invention discloses a high concentration small water quantity biochemical sewage treatment system comprising an anaerobic section, the anaerobic section comprises a regulating tank A and an anaerobic tank, the upper part of the anaerobic tank is provided with a inclined tube sedimentation zone I, a second sewage outlet is arranged above the inclined pipe sedimentation zone I, a sludge outlet and a sewage inlet are arranged on the lower part of the anaerobic tank, the regulating tank A includes a sewage inlet, a sludge return port, a dosing port, flue gas temperature regulating water and asewage outlet, the top of the anaerobic tank is provided with a biogas outlet, the sewage outlet is connected to the sewage inlet, and the sludge outlet is connected to the sludge outlet. The high concentration small water quantity biochemical sewage treatment system is suitable for the treatment of high concentration small water quantity sewage such as wastewater generated by a garbage transfer station, wastewater generated by food processing factory and catering industry, and wastewater generated by animal breeding.

Description

technical field [0001] The invention relates to a biochemical sewage treatment system with high concentration and small water volume. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Due to the more complex components of wastewater, some of which are toxic, wastewater treatment is more difficult and more important. How to treat the waste water in a targeted manner according to the characteristics of the waste water? What are the principles of wastewater treatment, how should it be classified, and how should wastewater from different industries be treated? [0003] In wastewater with high concentration and small water volume, the concentration of harmful substances is high. Due to the small amount of water and high concentration of pollutants, it is difficult to adopt biolog...
