Mine wastewater treatment chemicals
1. Oxidizing agents: Oxidizing agents can promote the oxidation and decomposition of organic matter and suspended solids in wastewater into harmless substances such as carbon dioxide and water. Potassium permanganate peroxide is usually used as an oxidizing agent for treatment.
2. Precipitant: Coal mine wastewater often contains a large amount of difficult-to-dissolve heavy metal ions and other granular substances. The use of precipitant can make these solid substances condense into granular substances in the water and precipitate to the bottom of the water to achieve purification. water quality purposes. Commonly used precipitants mainly include ferric hydroxide, polyaluminum sulfate, etc.
3. Biotechnological agents: Solid waste, dust and other substances in coal production contain a large amount of organic matter and nutrients. Biotechnological agents can be used to increase the amount of microorganisms in coal mine wastewater, which can degrade organic matter into non-toxic substances through biological phagocytosis. substances, so that the purpose of purifying water quality can be achieved. Biotechnological agents mainly include biomass, microbial agents, enzyme preparations, etc.
4. Foam inhibitors: During the treatment of coal mine wastewater, certain foaming methods will occur due to the action of oxidants and other chemicals. If not controlled, it will affect the effectiveness of wastewater treatment. At this time, it is necessary to use a foam suppressor agent, which can reduce the amount of foam in the sewage and improve the water treatment effect. Commonly used antifoam agents include silicone oil, polysiloxane, etc.
