Secondary precipitation type sewage purification treatment device

Abstract

The invention provides a secondary precipitation type sewage purification treatment device, which belongs to the technical field of sewage treatment. The deflectors are arranged alternately on both sides of the inner cavity of the first settling tank; the right end of the water suction pump passes through the water suction pipe and The second settling tank is connected, and the left end of the water suction pump is connected with the water outlet bucket through the water suction pipe; the lower end of the motor is provided with a disinfection device; the ozone generator is connected with the ventilation pipe through the gas delivery pipe; It is arranged at the upper end of the inner cavity of the second sedimentation tank; the activated carbon layer is arranged under the inner cavity of the purification tank; the device of the present invention is fixed with a disinfection sheet on the rotating shaft, and has rotating and stirring sewage and flocculants to facilitate precipitation and disinfection Ozone generator is welded and fixed on the upper left side of the second settling tank, which has the function of avoiding the growth of anaerobic bacteria and oxidizing domestic sewage at the same time; this device has simple manufacturing process, strong practicability and good decontamination effect specialty.

Description

technical field [0001] The invention relates to a facility related to environmental protection and purification, in particular to a secondary precipitation type sewage purification treatment device. Background technique [0002] With the continuous development of society, people have become more and more aware of the importance of environmental protection for human development. Sewage treatment is an important field of environmental protection; a common method of sewage treatment is sedimentation, but in the process of modern sewage treatment , the flow rate of sewage entering the settling chamber is relatively fast, which leads to a long time for settling, which greatly reduces the speed of sewage treatment. At the same time, modern sewage settling treatment generally only settles once, resulting in many smaller sewage Impurities cannot be settled, which brings a lot of trouble to the later sewage treatment. At the same time, the sterilization and disinfection of modern sew...
