Under alkaline conditions, the cyanide in the oxidizing wastewater of NaClO can be divided into two stages. First, the cyanide is oxidized to cyanate and further oxidized to carbon dioxide, ammonia and nitrogen. According to the nature of this segmentation reaction, in the treatment of cyanide-containing wastewater, the oxidation reaction is controlled to complete the first stage, and then CNO - hydrolyzed to C0 2 and NH 3 (referred to as incomplete oxidation); of NaClO, so CN - completely oxidized to CO 2 and N 2 (referred to as fully oxidized). Chlorinated Polyvinyl Chloride
Chlorinated Polyvinyl Chloride is a thermoplastic produced by chlorination of polyvinyl chloride resin. CPVC is significantly more flexible than PVC, and can also withstand higher temperatures. Uses include hot and cold water delivery pipes and industrial liquid handling. CPVC, like PVC, is deemed safe for the transport and use of potable water.
Chlorinated polyvinyl chloride (PVC) is a new type of engineering plastic made by chlorination modification of polyvinyl chloride (PVC) resin. The product is white or light yellow tasteless, odorless, non-toxic loose particles or powder. After chlorination of PVC resin, the irregularity of molecular chain arrangement increases, the polarity increases, the solubility of the resin increases, the chemical stability increases, thereby improving the heat resistance of the material and the corrosion resistance of acid, alkali, salt, oxidant and so on.
