A method and system for wastewater treatment

Abstract

The present application relates to the field of sewage treatment, and particularly to a sewage treatment method and system, which obtains and analyzes the circulating flow data of sewage in a primary tank, determines the distribution of solid matter of the sewage, and adjusts the pretreatment of the sewage in the primary tank; according to the water quality hardness of the reclaimed water produced by the primary tank, the reclaimed water is shunted and delivered to a plurality of softening tanks; according to the oxygen dissolution state in an aeration tank, the input state of the softening water to the aeration tank is dynamically adjusted, and the output of the oxygenated water is extracted from the aeration tank in a region; according to the water quality characteristic change trend in a reverse osmosis tank, the operating parameters of the reverse osmosis tank are adjusted, so as to produce purified water. The present application can comprehensively improve all processes in the whole process of sewage treatment, ensure that each process can efficiently purify and remove corresponding types of pollutants, and improve the sewage treatment efficiency, the purified water recovery rate and the water quality.
