Sewage treatment equipment

Abstract

The invention relates to sewage treatment equipment, which comprises an odor removal chamber; a flocculation chamber, wherein a flocculation concentration detector and a timer are arranged at the bottom of the flocculation chamber; a filtering chamber, wherein a reflux pipe is connected between the side wall of the bottom and the side wall of the top of the filtering chamber, and a filtering concentration detector is arranged at the bottom of the filtering chamber; a biological treatment chamber, wherein an oxygen concentration detector is further arranged in the biological treatment chamber;a degerming chamber; a residue treatment chamber; and a central control processor, wherein a preset numerical value is pre-stored in the central control processor. According to the invention, valves are arranged among the chambers, so that the chambers can independently treat sewage; the designated detectors are arranged in each chamber, the detection data and the pre-stored data are compared, andthe valves are controlled to be opened and closed according to the comparison results, so that the sewage can be conveyed to the next chamber under the condition that the sewage treatment of the previous chamber reaches the standard so as to reduce the content of the corresponding impurities in the sewage to a standard value after each chamber treats by using a specified process and improve the overall treatment efficiency of the sewage treatment equipment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. At present, a lot of domestic sewage is directly discharged into the environment, which seriously affects the environment. [0003] Sewage treatment refers to the purification process that treats sewage to meet the requirements of a certain water body or can be reused. People's lives and va...
