The Drinking Water Disinfection Technique Craft Is Excellent To Turn A Research

The method that our drinking water disinfect mainly has the liquid chlorine to disinfect, two oxidize chlorine disinfection, the ultraviolet ray C to wear to project light upon to disinfect deeply and ozone to disinfect etc.. The local great majority water factory still follows to use a traditional mixture, flocculate ,precipitate, filter currently, the chlorine disinfect of the water processing craft, although the chlorine disinfection disinfect effective, the cost is low, think towards cleaning the aquatic organic matter result disregard, would also born 20 various vice- outcomes, include three bittern methanes, the bittern acetic acid etc. carcinogen. This text carries on a comparison to four kinds of function, merit and shortcomings and vice- outcome that the in common use drinking water disinfects; Made use of the plum state the raw water that some water factory use to carry on the ClO₂ and Cl₂ to combine to disinfect effect and it to the on trial research that disinfects the vice- outcome control result, analyzed the ClO₂ and Cl₂ hurl to add in proper order, throw to add quantity and throw to add a combination to disinfect born influence regulation of the result and its chloroform. The research expresses the ClO₂ and Cl₂ combine to disinfect to have good disinfection result as a result, and can show the born quantity that lowers chloroform of the evidently ground. The hurl that disinfects adds sequence to have certain influence to the disinfection result, but the combination disinfect born quantity of the chloroform that the hurl adds a way all low in throw to add Cl₂ alone for born quantity;The adoption throws first to add the ClO₂3.0 mg/L, throwing again a combination method of add 0.5～1.0 mg/L Cl₂ can obtain satisfied disinfection result. With other disinfect to ompare, two oxidize a chlorine to have speed of disinfect quickly and disinfect a table widely, the deodorization take off a color, don't pollute environment to the human body health etc. advantage. Pass this research, the aim is exploring the excellent chemical engineering skill that the in keeping with plum fluid matter characteristics in state City cans look after both sides the social performance and economic performance to combine together drinking water of have the maneuverability combine to disinfect.
