The Research On Unidted Sterilization Algaecide Technology Of Ozone And Chlorine Dioxide

In recent years , more attention has been attracted to algae pollution . Algal bloom , rapid deterioration of water quality , bring the serious harm to the urban landscape water, sewage treatment systems and water supply systems : Reduced the water use efficiency, caused serious ecological damage and huge economic losses . Therefore development of effective sterilization algaecide technology is a urgent problem to be solved .At home and abroad , chemical oxidation method is the most commonly used technology , and most sophisticated technology. The technology is to use chemical oxidants to kill bacteria and algae , but now the number of chemical oxidant for the sterilization algaecide is considerable, having secondary pollution, and inhibiting the short statute of limitations problem .Based on the domestic and foreign technology study, the thesis use PSA , high concentration of ozone technology and Catalytic electrolysis technology , After optimizing and form a system . The system use the high oxidized active ozone and chlorine dioxide to kill algae and bacteria. And on this basis to develop laboratory experiments , based on the technical parameters of the experiments, determine the total process of industrialization, and develop auxiliary processes to make sure the main technological process for normal work . According to the process for select the main equipment have been carried on. The main work is as follows:1. Make the theoretical research on United sterilization algaecide mechanism of ozone and chlorine dioxide, preliminary determine the experiment scheme.2. Finish the ozone, chlorine dioxide single and combined sterilization algaecide experiments . Compare experiment results, obtained the best process parameters.3. Based on the results of the experiments, determine the total process of industrialization, and develop auxiliary processes to make sure the main technological process for normal work . According to the process , select the main equipment have been carried on.Through the system treatment , water quality reached national standards for drinking water. The sewage treatment system is suitable for regeneration , drinking water disinfection etc. When treating various Sewage water, the dosage depends on the concentration of mass and the usage of water after treatment.
