Sewage sampling device based on valve control system

Abstract

The invention relates to a sewage sampling device based on a valve control system. Electric control valves are arranged in a water inlet pipeline, a water drainage pipeline and a sample reserving pipeline of a sampling pool; a water quality acquisition sensor is arranged in the sampling pool, a micro water-turbine generator set is arranged in the water inlet pipeline, and the water quality acquisition sensor, the micro water-turbine generator set and the electric control valves are in signal connection with the acquisition control device; the micro water-turbine generator set sends a wake-up signal to the acquisition control device; the water quality acquisition sensor acquires water quality data; the acquisition control device sends out a first control signal according to the wake-up signal and sends out a second control signal and a third control signal according to the water quality data; the electric control valves open the sewage discharge channel according to the first control signal, close the sewage discharge channel according to the second control signal, and open the sewage sample reserving channel according to the third control signal. The sewage sampling device automatically controls and monitors sewage discharge in real time, is dormant when no sewage is discharged, is automatically awakened when sewage is discharged, automatically detects water quality, reserves a sample for reinspection, and is energy-saving and environment-friendly.

Description

Technical field [0001] The present invention relates to the field of sewage discharge control technology, and more particularly to a sewage sampling device based on a valve control system. Background technique [0002] With the increasing development of society, industrial sewage and domestic sewage emissions are increasing. If the sewage discharge is not effective, the sewage will cause a harsh impact on the environment. Sewage is infiltrated into the water body, and the water body is contaminated by toxic and harmful chemicals. It may cause poisoning phenomena by drinking water or food chain, such as the famous water, pain, and the like are caused by water pollution. Metal elements in sewage, such as copper, zinc, nickel, etc., can inhibit the growth and reproduction of microorganisms at a certain concentration, thereby affecting the decomposition and biocioxidation of the organic matter in water, so that its self-cleaning capacity is weak, affecting the sanitation of the water...

Problems solved by technology

This kind of water quality detection cycle is long, the efficiency of sewage discharge control is low, and it takes a lot of manpower, resulting in high time and labor costs.
