Concentration and precipitation machine of high-concentration tailing waste water

Abstract

The invention provides a concentration and precipitation machine of high-concentration tailing waste water. The concentration and precipitation machine is characterized by comprising a clean water area (1), an inclined tube area (2), a separation area (3) and a concentration area (4). The clean water area (1) is located above the inclined tube area (2). The concentration area (4) is located below the inclined tube area (2). The separation area (3) is located between the inclined tube area (2) and the concentration area (4). A fundamental of the concentration and precipitation machine of high-concentration tailing waste water is a shallow precipitation theory. Based on the shallow precipitation theory, the residence time of water in a precipitator is greatly reduced; effects of the concentration and precipitation machine is two times better than that of a horizontal-flow sedimentation tank; and a sedimentation area is reduced. Therefore, the concentration and precipitation machine of high-concentration tailing waste water has the advantages of good adaptability for raw water with a wide change scope of turbidity, high treatment efficiency, small floor space, and good convenience of management.

Description

technical field [0001] The invention relates to a high-concentration tailings wastewater concentrating precipitator. [0002] Background technique [0003] At present, mining washing wastewater can also be used for tap water treatment projects and other industrial wastewater. During the treatment, coagulants need to be added to the sewage, so the investment and facilities increase, resulting in an increase in floor area and maintenance costs. [0004] Contents of the invention [0005] The main purpose of the present invention is to provide a high-concentration tailings wastewater concentrating precipitator for treating higher-concentration wastewater, especially suitable for mining washing wastewater, and can also be used in tap water treatment projects and other industrial wastewater treatment projects. The ground area is small, the surface load is large, and the treatment effect is remarkable. Technical scheme of the present invention is: The high-concentration ...

Problems solved by technology

[0003] At present, mining washing wastewater can also be used for tap water treatment projects and other industrial wastewater. During the treatment, coagulants need to be put into the sewage, so the investment increases and the number of facilities increases, resulting in an increase in floor space and maintenance costs.
