Control device for performing impurity blocking and clean water overflowing on combined sewage

Abstract

The invention discloses a control device for performing impurity blocking and clean water overflowing on combined sewage. The control device comprises an NH3-N on-line monitoring instrument, a sensor, a relay, an impurity blocking electric gate and a clean water overflowing electric gate, wherein the NH3-N on-line monitoring instrument, the sensor and the relay are sequentially connected with one another; the impurity blocking electric gate and the clean water overflowing electric gate are respectively connected with the relay; the NH3-N on-line monitoring instrument senses and identifies the NH3-N concentration in the sewage; the sensor converts the NH3-N concentration sensed and identified by the NH3-N on-line monitoring instrument into an electric signal; the electric signal is transmitted to the relay; and the relay controls the turn-on or turn-off of the impurity blocking electric gate and the clean water overflowing electric gate according to the electric signal. By the control device, impurities of high-concentration-charge sewage are blocked and purified, and clean water of low-concentration-charge sewage overflows, so that high-efficiency impurity blocking and clean water overflowing on the sewage are realized, and intelligent flow division control is realized.

Description

technical field [0001] The invention relates to an intelligent control technology for intercepting and overflowing sewage, especially by identifying NH in combined sewage 3 -N concentration, a control device that automatically realizes pollution interception and overflow cleaning. Background technique [0002] At present, due to the initial scouring effect of rainy season rainfall, the initial rainwater carries most of the pollutants produced in a single rainfall. Peak high-load pollution and subsequent large-scale traffic shocks have limited processing capacity. When it rains, especially during heavy rain, it is difficult to intercept all the rainwater and sewage, and then carry out effective purification and other treatment; in this way, the overflow of confluent sewage in the rainy season will cause serious pollution to the receiving water body in the city. Taking Kunming as an example, according to the relevant research of the "Tenth Five-Year Plan" National High-tech ...
