Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a mine sewage treatment device. Background Art

[0002] With the rapid development of social economy, the demand for mineral resources is increasing day by day. The discharge of industrial wastewater generated in the mining and processing of mineral resources is also increasing. Mine wastewater has become one of the key industrial pollutions that my country needs to solve urgently. Acid mine drainage (AMD) is rich in heavy metal ions and is extremely harmful to the environment: on the one hand, the acid in the wastewater will have an adverse effect on the growth of aquatic organisms and corrode metals and concrete structures in the water; on the other hand, heavy metal ions will damage the water environment, endanger fishery and agricultural production, and pollute drinking water sources. Therefore, removing heavy metal ions from acid mine drainage is a very important research topic, and its treatment technology should be developed in the direction of circulating water and heavy metal recovery; mine sewage treatment under existing technology usually carries out a filtration process, while acid wastewater treatment under existing technology, more than 90% will choose to use neutralization method to treat acid wastewater. The so-called neutralization method is to add an alkaline neutralizer to the wastewater containing heavy metal ions, so that the metal ions in the wastewater react with hydroxide to form insoluble hydroxide precipitates, which are separated and removed. Commonly used neutralizing agents include soda lime, slaked lime, fly ash, calcium carbonate, blast furnace slag, dolomite, sodium carbonate, caustic soda, etc. Such neutralizing agents can remove heavy metal ions other than mercury, with simple processes and low treatment costs. For example, copper and chromium in wastewater can be removed by lime precipitation, and the effluent quality meets the discharge standard. However, the precipitated sludge after treatment by this method is huge in volume, accounting for about 10% to 60% of the wastewater volume, and the sludge has a low solid content, which is difficult to dispose of and can easily cause secondary pollution. If the sludge in the sedimentation tank is returned to the reaction tank and flocculants are added during the sedimentation process, the sedimentation rate can be accelerated, the generated sedimentation particles can be enlarged, the sludge sedimentation performance can be improved, the water content can be reduced, the sludge amount can be reduced, and the dosage can also be saved. However, there is still the problem that impurities attached to the filter are difficult to remove. Utility Model Content
