Multistage treatment equipment for domestic sewage

Abstract

The invention provides domestic sewage multistage treatment equipment, which comprises a box body, a base, a primary filtering mechanism, a secondary filtering mechanism, a dosing mechanism, an ozonegeneration mechanism and a distillation mechanism; the box body is mounted at the upper part of the base, and a dosing chamber, a pump chamber, a reaction chamber and a distillation chamber are arranged in the box body; a first-stage filtering mechanism and a second-stage filtering mechanism are arranged in the dosing chamber, a feeding port is formed in the side wall of the box body, the dosing mechanism is arranged in the dosing chamber, a suction pump and a water pumping pipe are arranged in the pump chamber to achieve communication between the dosing chamber and the reaction chamber, and the ozone generation mechanism is installed at the top of the box body; a drain pipe is arranged at the bottom of the side wall of the reaction chamber for communicating the reaction chamber with the distillation mechanism; a water outlet pipe is arranged at the bottom of the distillation chamber, a controller is arranged in the base, and the suction pump is in signal connection to the controller.By means of the device, the sewage and household garbage can be screened through multi-stage filtration, and sewage is subjected to multi-stage treatment in treatment modes such as agent stirring andozone reaction stirring, so that the sewage treatment effect is better.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a multi-stage treatment equipment for domestic sewage. Background technique [0002] The domestic sewage generated in people's daily life and the industrial wastewater generated in the daily production of factories must be treated before being discharged into the river to avoid the impact of the discharged sewage on the surrounding environment. The existing sewage multi-stage treatment equipment Each step of the treatment process is carried out in different areas. This treatment method is likely to reduce the sewage treatment efficiency and increase the production cost of the equipment; the filtering effect is not very satisfactory. At the same time, most of the sewage dosing devices in the prior art are directly Putting the chemical into the sewage does not consider the conditions for the full reaction of the sewage and the chemical, such as temperature; finally, the reaction bet...

Problems solved by technology

[0002]The domestic sewage generated in people's daily life and the industrial wastewater generated in the daily production of factories must be treated before being discharged into the river to avoid the discharge of Sewage has an impact on the surrounding environment. The existing multi-stage sewage treatment equipment divides each step of the treatment process into regions. This treatment method tends to reduce the efficiency of sewage treatment and increase the production cost of the equipment; the filtering effect is not very ideal. At the same time , Most of the dosing devices for sewage in the prior art directly put the medicine into the sewage, without considering the conditions for the full reaction of the sewage and the medicine, such as temperature; finally, the reaction between the sewage and ozone, most of the existing equipment has a reaction Insufficient situation, in summary, the existing equipment cannot handle the sewage more adequately
