High-precision sewage treatment control system

Abstract

The invention discloses a high-precision sewage treatment control system. A first valve, a second valve and a third valve are arranged at a first outlet, a second outlet and a third outlet at the bottom of a filtration tank respectively; the first outlet, the second outlet and the third outlet communicate with a purification tank through a first pipeline, a second pipeline and a third pipeline respectively; a first pump, a second pump and a third pump are arranged on the first pipeline, the second pipeline and the third pipeline respectively; a detection device is used for detecting the viscosity of liquid in the filtration tank; and a control device controls the actions of the first valve, the second valve, the third valve, the first pump, the second pump and the third pump by instructions according to the comparison result of the viscosity of the liquid in the filtration tank and the preset viscosity. The high-precision sewage treatment control system disclosed by the invention can select the pump to convey the liquid in a targeted manner according to the viscosity of the liquid, so that not only the problem that the energy is wasted when the pump with relatively high working power is selected, but also the problem that the liquid conveying efficiency is reduced when the viscosity of the liquid is too high and the pump with relatively low working power is selected can be avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment systems, in particular to a high-precision sewage treatment control system. Background technique [0002] With the increase of urban population and the development of industrial and agricultural production, the amount of sewage generated in production and living processes is also increasing. In order to reduce the harm of sewage to water bodies and the environment, it needs to be purified before it is released into the environment. link. Most of the existing sewage treatment systems are composed of a pretreatment system, a biochemical treatment system and a mud-water separation system, and the treatment process is relatively complicated. In the process of sewage treatment, pumps are needed to increase the kinetic energy of sewage, but the existing sewage treatment systems all use pumps of the same power to discharge sewage.

AI Technical Summary

Problems solved by technology

Most of the existing sewage treatment systems are composed of pretreatment systems, biochemical treatment systems and mud-water separation systems, and the treatment process is relatively complicated.

In the process of sewage treatment, pumps are needed to increase the kinetic energy of sewage, but the existing sewage treatment systems all use pumps of the same power to discharge sewage. When the viscosity of sewage is low, excessive power may cause It causes waste of energy. When the viscosity of the sewage is high, the constant power cannot provide sufficient kinetic energy for the sewage, which reduces the efficiency and effect of the sewage treatment process.
