Abstract

The invention relates to a silt and sewage treatment method, and belongs to the technical field of mine sewage treatment. The method comprises the following steps: (1) performing silt separation, namely performing primary separation on the silt and the sewage, and separating sand out; (2) performing sedimentation treatment, namely adding 0.2 to 0.4 mass percent solution of anionic polyacrylamide into the sewage, then adding 0.1 to 0.3 mass percent solution of anionic polyacrylamide into the sewage after sediment is generated, and separating the sediment out; and (3) performing sediment filter pressing, namely filter-pressing the sediment separated out by the step (2). The method of the invention effectively solves the mine sewage treatment problem, and separates three useful substances out comprising coarse sand, fine sand and sludge so as to increase the creation income of the enterprise.

Description

technical field

[0001] The invention relates to a mud sand sewage treatment method, which belongs to the technical field of mine sewage treatment. Background technique

[0002] The treatment of sewage generated by washing gravel has always been a major problem for mining enterprises. The traditional method generally uses three-stage sedimentation tanks to treat sewage. This method has been used in many mining enterprises until now. However, the three-stage sedimentation has many disadvantages. First, the sedimentation time is longer; second, the cleared silt contains more sandy components and other useful substances, and resources are lost in vain; third, the cleared silt has a high moisture content. , must be naturally dried before treatment, but the drying time is too long, not only occupying a large area of ​​land, but also may cause environmental pollution. Contents of the invention

[0003] The object of the present invention is to provide a method for treating mud ...
