Abstract

The invention provides a pollution repairing method for water polluted by organic matters. The method comprises the following steps: mixing metal Fe powder, metal Gd powder, metal Co powder and anhydrous aluminum silicate to obtain a mixture a; ball-milling the mixture a; thermally treating the ball-milled mixture a and carrying out surface treatment and centrifugal atomization to obtain micro powder for water treatment, adding the micro powder for water treatment to a PVC (Poly Vinyl Chloride) spinning solution and stirring to obtain a composite PVC spinning solution; forming the composite PVC spinning solution into a water treatment flexible layer by utilizing an electrospinning method; adding an oxidizing agent and a chelating agent to the water polluted by the organic matters and adjusting the pH (Potential of Hydrogen) value to obtain initially-treated sewage; and enabling the initially-treated sewage to circularly flow through the water treatment flexible layer. Compared with theprior art, the pollution repairing method disclosed by the invention has the advantages that the pollutant eliminating efficiency is higher and the problem of secondary pollution is hardly consideredin the water treatment process.

Description

technical field [0001] The invention relates to the field of water treatment methods, in particular to a pollution restoration method for water polluted by organic matter. Background technique [0002] With the reform and opening up of our country, our country's social economy has developed rapidly. At the same time, our country's population is growing rapidly and intense activities, as well as expanding industrial and agricultural production. There are more and more types of toxic and harmful pollutants produced and discharged by human beings, resulting in serious pollution. Rivers, lakes, etc. are important receiving environments for various pollutant discharges, presenting a composite, regional, long-term and systematic pollution trend. Natural water bodies such as rivers and reservoirs are an important guarantee for human life and biological survival, and the problem of water pollution has always been one of the most concerned issues in various countries. Water polluti...
