Description

Purification device for underground water of mine

Technical Field

The utility model belongs to the technical field of sewage treatment, and particularly relates to a purification device for mine underground water.

Background

With the rapid development of social economy, the national demand for energy is rapidly increased, and the coal mining quantity and the mining depth are increased. In the coal mining process, underground water is in contact with a coal bed and a rock stratum, a series of physical, chemical and biochemical reactions can occur, the content of suspended matters in the underground water of a mine is far higher than that of surface water, the sensory property is poor, the suspended matters in the underground water of the mine are small in granularity, light in specific gravity, low in settling speed and poor in coagulation effect, and meanwhile, organic pollutants such as waste engine oil and emulsified oil are contained, if the suspended matters are not subjected to purification treatment, the organic pollutants are directly discharged, so that the environment is seriously polluted, the ecological environment is unbalanced, and the health and the safety of human beings are threatened.

In the process of purifying the mine underground water, the flocculation sedimentation tank is used as an important purification treatment device and is a key factor for determining the water treatment effect. The flocculating and settling tank is added with a flocculating agent, and under the action of the flocculating agent, colloidal particles in the sewage are gathered to form larger particles so as to facilitate precipitation and meet the requirement of water purification in water treatment. Since the flocculating agent is usually in powder or granular form, if the flocculating agent is directly added into sewage, the flocculating agent is generally difficult to dissolve, and the flocculating effect is influenced. Therefore, in the flocculation sedimentation tank, the sewage and the flocculant are generally mixed and stirred by using the stirring blades so as to ensure that the flocculant is fully dissolved in the sewage. However, in the stirring process, can produce a large amount of bubbles, the bubble can carry partial colloidal particle to float on the sewage surface of water, not only can influence the effect of flocculation and precipitation, and the a large amount of bubbles that produce moreover make the sewage surface of water rise, lead to sewage to spill over the flocculation and precipitation pond outside, influence sewage treatment's normal clear.

At present, defoaming agent is added into a flocculation sedimentation tank to eliminate bubbles generated in the stirring process. However, the addition of the defoaming agent not only affects the performance of the flocculating agent and reduces the flocculation effect, but also increases the consumption of the defoaming agent, increases the cost of sewage treatment, and may cause secondary pollution due to the addition of too much defoaming agent.
