A monitoring system for mine water quality treatment based on multiple treatment

Abstract

The invention provides a multiple treating-based mine water quality treating and monitoring system. According to the system, a water quality control host can correspondingly compare a fluoride content, a chloride content, a sulfate content and a salt content in mine water in a certain water-out sump with preset threshold values after a liquid level meter of the water-out sump senses a liquid levelsignal, and control starting of a reflux valve and operating of a reflux pump when a certain content exceeds the corresponding preset threshold value, so as to enable the mine water in the water-outsump to return to a mine water treating mechanism for secondary treatment. When water quality is unqualified, secondary treatment is performed. The system is provided with a plurality of water-out sumps, so that the treated mine water can be separately stored; if the water treatment is unqualified, the treatment process can be suspended to adjust the medicament and ratio, and then the treatment can be carried out to ensure that the water treatment can meet the requirements. The system can avoid the phenomenon that when detection is carried out after treatment of a large quantity of mine water,repeated treatment is required if a large quantity of water is unqualified in quality.

Description

technical field [0001] The invention relates to the field of coal mines, in particular to an underground water quality treatment monitoring system based on multiple treatments. Background technique [0002] In order to avoid the impact of coal mine sewage on the geological environment of the mining area and the ecological system around the mining area, and to meet the normal production needs, it is necessary to recycle the mine water, which not only protects the safety of mining production and water supply in the mining area, but also protects the surrounding environment. . Mine water includes underground gushing water, mining equipment dust washing, mining staff domestic water, etc., with various sources and complex water quality. Most mine water is a kind of high sulfate, high hardness, large suspended solids content, and complex components, which makes it difficult to treat. , and the emissions are large. [0003] At present, the commonly used underground sewage treatme...

Problems solved by technology

This brings great preparations in advance for coal mining preparations, and the scattered arrangement of treatment equipment makes it impossible to achieve centralized management of sewage treatment, resulting in high investment costs and high operating costs.

[0004] Moreover, at present, after the mine sewage is treated in each mining area, it is used later. It is often impossible to know the water quality after treatment. Some areas have set up water quality testing after treatment, which is usually carried out manually and used after testing. It is difficult to obtain evidence when the record book is recorded and checked later, and no records are left on the testing process, which makes it easy to cause artificial influence on water quality testing

[0005] In the existing technology, it is impossible to monitor the entire detection process and obtain data, resulting in a lack of basis for parameter design or adjustment, and the inability to improve the effect of water treatment
