Integrated sewage treatment equipment with front-end pretreatment function

Abstract

The invention discloses the field of integrated sewage treatment equipment with a front-end pretreatment function. The equipment comprises an adjusting tank, an integrated sewage treater, a water production tank and a water distribution well, wherein algae and photosynthetic bacteria are arranged in the water distribution well; an aerator is arranged at the bottom of the water distribution well, and the aerator is connected with an air blower; the adjusting tank is connected to the water distribution well through a water pump; the lower part of the water distribution well is connected into ananoxic tank through a water pump. Under the stirring action of the aerator in the water distribution well, on the premise that dissolved oxygen in the tank is not increased, the phenomena that sludgeis accumulated for a long time, deteriorates and smells and floats upwards due to anaerobic reaction are prevented, and the effect of improving the environment in the tank is achieved; an algal-bacterial symbiotic mode is formed in the water distribution well, so that the sewage pretreatment effect is greatly improved, the water feeding load of integrated sewage treatment equipment is obviously reduced, and the water discharge stability of the system is enhanced. The operation is simple, the energy consumption is reduced, and the investment cost is saved.

Description

Technical field [0001] The invention relates to an integrated sewage treatment equipment with front-end pretreatment, belonging to the technical field of sewage treatment equipment. Background technique [0002] In recent years, on the basis of continuous promotion of urbanization, the construction of villages and towns in our country has developed rapidly. Due to the imperfect domestic sewage treatment facilities in villages and towns, more than 95% of residents' domestic sewage and fecal sewage are discharged into natural water bodies without treatment. It has caused serious pollution to local water sources, groundwater sources and the surrounding environment, and the water resources situation has seriously deteriorated. According to statistics, as of the end of 2019, the sewage treatment rate in urban areas in my country has reached 90%, the sewage treatment rate in county areas has reached 85%, but the sewage treatment rate in villages and towns is only 20%. The rural popula...

Problems solved by technology

[0003] Through long-term tracking of existing integrated domestic treatment equipment, it is found that due to differences in local living standards and customs, the concentration of pollutants in sewage varies greatly. The treatment of integrated sewage treatment equipment for rural domestic sewage in different regions The effect is not the same
