Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to waste water purification and discharge treatment equipment. Background technique [0002] With the development and progress of China's industrial technology, the scale of production has expanded accordingly, and has penetrated into various fields of modern industry, which has a non-negligible role in promoting the development of modern industry. Moreover, with the improvement of China's market economy, environmental protection requirements are becoming increasingly stringent. We are required to increase the efficiency of wastewater production while reducing the discharge of wastewater. Wastewater is high-suspended solids, high-ammonia-nitrogen wastewater, and contains silicon-aluminum gel, which is not easy to precipitate. Due to technical and economic reasons, the process wastewater in the chemical industry has not been effectively treated. If it is not treated, it...

[0002] With the development and progress of China's industrial technology, the scale of production has expanded accordingly, and has penetrated into various fields of modern industry, which has a non-negligible role in promoting the development of modern industry. Moreover, with the improvement of China's market economy, environmental protection requirements are becoming increasingly stringent. We are required to increase the efficiency of wastewater production while reducing the discharge of wastewater. Wastewater is high-suspended solids, high-ammonia-nitrogen wastewater, and contains silicon-aluminum gel, which is not easy to precipitate. Due to technical and economic reasons, the process wastewater in the chemical industry has not been effectively treated. If it is not treated, it will directly affect the qualified rate of sewage in the chemical industry. Wastewater is wastewater with high concentrations of organic matter, sulfur-containing substances, and phenols. Glue, not easy to settle, resulting in high suspended solids in the effluent of the secondary sedimentation tank in the existing process, the filler of the biochemical system is easily blocked, affecting the treatment effect of the system, and the effluent quality is prone to fluctuations. The traditional method of treating wastewater is mainly flocculation with drugs. Adding polyaluminum or polyacrylamide flocculant to the settling tank to flocculate and precipitate, this method has a large dosage of chemicals, will produce a large amount of sludge, and requires higher operating costs. Large, resulting in a certain labor burden
