AI Technical Summary

Problems solved by technology

The quality of water treatment first depends on whether the dosage is timely and accurate. If the dosage is too small, the coagulation will be insufficient, and if the dosage is too large, it will cause waste and increase the cost.
In the previous water treatment dosing process, most of the dosing amount was determined by the experience of workers, which not only made the dosing amount inaccurate and failed to achieve the coagulation effect, but also caused waste
With the development of the economy, this method can no longer adapt to the requirements of the times

Abstract

The invention relates to an automatic sewage chemical feeder which has the structure that: a source water flowmeter (1) is connected with a PLC (Programmable Logic Controller) (2) which is connected with a frequency converter (3), the frequency converter (3) is connected with a metering pump (4) which is connected with a reaction tank (5), the reaction tank (5) is connected with a sampler (7) which is connected with an SCD (Streaming Current Detector), and the SCD is connected with the metering pump (4). The invention can improve the water quality, reduces the chemical consumption, has the remarkable advantages of real time, reliability, safety, maintainability and the like, and ensures the accuracy of the chemical addition, thereby lowering the production cost and improving the economic benefit.

Description

Technical field: [0001] The invention relates to an automatic sewage dosing device. Background technique: [0002] Water is the source of life, and the quality of water is the guarantee of life. The development of industry has led to the rapid development of related industries and has become one of the important pillars of the national economy. However, countries that have undergone rapid industrial development understand that industrial development also means the destruction of the natural environment, especially the serious pollution of water sources, so the protection of water sources, sewage treatment, and water purification are very important. With the continuous improvement of people's living standards, health awareness is increasingly strengthened, especially in hospitals, chemical laboratories and other units, which also put forward higher requirements for the quality of water. This means that the urban waterworks must improve the production process and improve the...
