Problems solved by technology

[0003] However, the treatment technology of alkali neutralization method has the disadvantages of high energy consumption, high labor cost, large consumption of chemicals, rapid equipment corrosion, difficulty in collecting and treating dispersed mine wastewater, and high operating cost of continuous pollution source treatment. The use of sludge has led to a surge in sludge production, making sludge disposal costly

Abstract

The invention provides a flexible crystallization filler for an acid mine wastewater treatment system, as well as preparation method, device, treatment process and system of same, and relates to the technical field of wastewater treatment; the flexible crystallization filler comprises flexible fibers, crystal nucleuses and a binder, and the device comprises a water distribution well, a flexible crystallization sedimentation tank and the flexible crystallization filler. According to the mine wastewater treatment system device provided by the invention, the characteristic pollutants in the wastewater can form crystals by taking the crystal nucleus as the center, so that the pollutants are separated from the wastewater to achieve the purposes of purification and impurity removal, an alkaline agent and a flocculating agent do not need to be added into the wastewater during the period and power equipment does not need to be used; therefore, the advantages of low sludge yield, high sludge removal efficiency, small occupied area and the like can be achieved, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a flexible crystalline filler used in an acid mine wastewater treatment system, a preparation method, a device, a treatment process and a system thereof. Background technique [0002] At present, in the treatment of acidic wastewater containing iron in mines, neutralization with alkali is the most widely used method. The basic principle is to add a certain amount of alkaline materials and flocculants to acidic wastewater containing iron to increase the pH value of the wastewater. , to promote metal ions to form hydroxides or carbonates and precipitate, then filter and discharge up to the standard. Among them, the commonly used alkaline materials are lime, slaked lime and sodium hydroxide, etc., and the commonly used flocculants are polyaluminum chloride and polypropylene amides etc. [0003] However, the treatment technology of alkali neutralization method has the d...
