Description

technical field

[0001] The invention relates to a coal washing water treatment agent, in particular to the composition of a coal washing water treatment agent. Background technique

[0002] The coal washing water after coal preparation contains a large amount of suspended solids. The suspended solids are extremely fine coal powder, mineral powder and other particles. The coal washing water needs to be treated to separate the suspended solids before it can meet the discharge standard or be recycled. The suspended solids in coal washing water are very fine particles, which are difficult to settle down. When treating coal washing water, it is necessary to add a treatment agent to the coal washing water to make the fine particles flocculate and settle down, so that the suspended solids can be separated. Among the treatment agents, polyacrylamide products are high-efficiency coal washing water treatment agents. When treating coal washing water, polyacrylamide products should be u...
