Study On Preparation Of Complex Polymeric Silicate And Treatment Of Coke Plant Wastewater

Coal is a more effective fuel, which is called basic material of iron and steel industry. By reason of extreme development of iron and steel industry in China, cock output is sharp enhanced and discharge amount of coke plant wastewater is rapid increased. Coke plant wastewater is a typical industrial wastewater, in which contains a great deal suspend solid,CODc_r, chroma and a number of toxic and nocuousness compounds, in which contains refractory organic compounds such as tar, benzene, phenoK cyanide, quinoline and pyridine etc. So chroma of that is high water and great changes happened usually to water quality and flow. The biological treatment processes deal with coke plant wastewater, which suspend solid, CODc_r and chroma of removal rate not favorable and the effluent concentration couldn't attain are the wastewater drainage level, which brought severe harm to our environment. Today the art for coking wastewater treatment can not meet with wastewater amount for now cock plants built twenty years ago. According to actual instances, physicochemical technique is a simple and economical method.There are two hundred more species of flocculants in modern wastewater treatment, which contains inorganic flocculants and organic flocculants. Types of organic flocculants are very much, but application is limited for mass of them have toxic. The application of inorganic flocculants is abroad. Inorganic macromolecule flocculants become leading flocculants in recent years because produce cost and price are lower than ordinary inorganic flocculants. In recent years, preparation and applications of complex polymeric silicate become fashionable. Their trait is little dose and better deposition capability, but their stability is of a sort and can not long-term save.This paper tends to prepare a new kind of the excellent polymeric silicate. The measure is...
