A biological wastewater treatment device

Abstract

The invention discloses a biological drainage treatment device, which comprises a vegetation reaction pool and a return pipe. The upper end of the vegetation reaction pool is provided with a water inlet pipe, and floating plants are placed inside the vegetation reaction pool. The water port is connected to the water inlet of the fungus reaction pool through the conduit, and the microbial bacteria are placed in the fungus reaction pool, and the water outlet of the fungus reaction pool is connected to the water inlet of the adsorption sterilization pool through the conduit. A filter mesh sheet, the surface of the water inlet pipe, the surface of the drain pipe, the conduit between the vegetation reaction pool and the fungus reaction pool, the conduit between the fungus reaction pool and the adsorption sterilization pool, and the connection between the adsorption sterilization pool and the drainage detection pool A solenoid valve is provided at the junction between the conduit, the return pipe and the return port, and a controller is provided outside the drainage detection pool, and the controller is electrically connected to the water quality detector and the solenoid valve.

Description

technical field [0001] The invention relates to the technical field of drainage treatment, in particular to a biological drainage treatment device. Background technique [0002] With the rapid development of social economy, the industrialization and urbanization of human society are intensifying, water pollution is becoming more and more serious, and even untreated sewage is directly discharged into rivers and lakes, which gradually pollutes rivers and lakes, and makes the water quality of rivers and lakes in my country Pollution control is extremely difficult. People have begun to pay attention to the treatment of various sewage, including the water environment of rivers and lakes, and reuse it as much as possible. At present, most of the sewage treatment devices in cities and towns use chemical additives to decompose them, so as to achieve the drainage effect, but this kind of drainage treatment device will cause a small amount of damage to the human body, and cannot achie...

Problems solved by technology

At present, most of the sewage treatment devices in cities and towns use chemical additives to decompose them, so as to achieve the drainage effect, but this kind of drainage treatment device will cause a small amount of damage to the human body, and cannot achieve the effect of environmental protection. Therefore, we propose a Biological Wastewater Treatment Plant
