Abstract

The invention relates to an integrated domestic sewage treatment method and device. Airflow stirring mechanisms are arranged in an anaerobic tank and an anoxic tank; the airflow stirring mechanism intermittently aerates and stirs sewage in a perforated aeration manner; an operation cycle of the airflow stirring mechanism is set to A, an aeration time is set to B, and then a rest time is C=A-B. Theintegrated domestic sewage treatment method and device provided by the invention can be adopted to improve quality of effluent water and reduce energy consumption.

Description

technical field [0001] The invention relates to the field of sewage treatment, and more specifically relates to an integrated domestic sewage treatment method and a device thereof. Background technique [0002] With the development of social economy and the improvement of people's awareness of environmental protection, the requirements for sewage treatment and discharge standards are becoming increasingly stringent. In recent years, Beijing, Tianjin and parts of Jiangsu have successively issued local discharge standards for sewage treatment. Compared with the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), these local discharge standards have stricter requirements for nitrogen, phosphorus, etc. Strict, has reached the surface level four water standards. However, due to the limitation of treatment scale, pipeline network construction conditions, topographical environment, etc., integrated sewage treatment equipment is usually used in areas w...
