STUDY AND APPLICATION OF MINE WATER PURIFICATION

摘要

One of the environmental pollution of mining process is a mine water. It consists of the suspension and oil emulsion. The particles of the suspension are sand, clay and cement. The wastewater is dumped to well or pound. In both cases it is necessary to purify of the sewage water. The properties of the pollution and a projected water treatment method have been investigated. The process includes the waste purification from oil emulsion in Tilted-Plate Separator and the suspension separation in the downward-flow sand-gravel filter. The packing recovery is made by back washing. The washing water is directed to Tilted-Plate Separator. The treated water is unnatural salt-free and has the constant contents. The design of the treatment plant has been projected.
