Abstract
The invention relates to a treatment method of beneficiation wastewater. The treatment method comprises steps as follows: the beneficiation wastewater is introduced into a wastewater pond, the pH (potential of hydrogen) value of the beneficiation wastewater is adjusted to range from 4 to 7, hydrogen peroxide and ferrous sulfate are added to the beneficiation wastewater, the mixture is stirred to be subjected to a reaction and then is subjected to standing for 10-20 hours, sediments in the beneficiation wastewater are removed, a supernatant is poured into a sedimentation tank, polyacrylamide is added, sedimentation is performed and sediments are filtered out, and recycle water is obtained. With the adoption of the treatment method of the beneficiation wastewater, the wastewater treatment effect is stable, efficient treatment is realized, the operation is simple, the technological procedure is short, the cost is low, and the method has the advantages of energy conservation, environment protection, and wide application prospects.
Description
Technical field
The present invention relates to a kind for the treatment of process of beneficiation wastewater, belong to water treatment field.
Background technology
Metal mine can produce a large amount of beneficiation wastewater in process of production, these waste water qualities are complicated, composition is various, containing various heavy, beneficiation reagent and other pollution substances, if outer row produces serious harm by surrounding ecotope, if recycled in Returning process, objectionable impurities in waste water will constantly be accumulated, adverse influence can be produced to production technique and equipment, therefore, need to select suitable treatment process to process flotation waste water.At present, conventional treatment process has chemical precipitation method, absorption method, microbial method, artificial swamp method etc., although these treatment processs have certain advantage separately, but generally by the restriction of the factors such as mining production condition, envrionment conditions or processing requirements, such as, adopt chemical precipitation method heavy metal treatment effect relatively better, but organic substance poor processing effect; Absorption method effectively can process heavy metal wastewater thereby, but during adsorbent reactivation, pollutent can regenerate again; Microbial method processing cost is relatively low, but reaction conditions requires harsher, is difficult to be widely applied; Wetland method area occupied is large, and long processing period, is also difficult to meet processing requirements.Therefore, how selecting a kind of reasonable, effective, practical beneficiation wastewater treatment method, is the difficult problem that current metal mine enterprise generally faces.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tin ore beneficiation wastewater treatment method, beneficiation wastewater treatment method of the present invention, and water treatment effect is stable, efficient, simple to operate, technical process is short, cost is low, and energy-conserving and environment-protective, have broad application prospects.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of beneficiation wastewater treatment method, comprising:
Beneficiation wastewater is introduced in wastewater disposal basin, regulate beneficiation wastewater pH value to 4-7, in beneficiation wastewater, add hydrogen peroxide and ferrous sulfate, after stirring reaction, leave standstill 10-20 hour, remove the throw out in beneficiation wastewater, supernatant liquor enters settling tank, adds polyacrylamide, sedimentation, filter out precipitation, obtain reuse water.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the add-on of described hydrogen peroxide accounts for the 1%-2% of beneficiation wastewater quality, and the add-on of described ferrous sulfate accounts for the 0.1%-2% of beneficiation wastewater quality.
Further, the add-on of described polyacrylamide accounts for the 0.1-1% of supernatant liquor quality.
The invention has the beneficial effects as follows:
Beneficiation wastewater treatment method of the present invention, water treatment effect is stable, efficient, simple to operate, and technical process is short, and cost is low, and energy-conserving and environment-protective, have broad application prospects.
