| titleOfInvention | Method for determining chlorine demand for rapid reaction in chlorine residual decay after chlorination |
| abstract | The invention discloses a method for determining chlorine demand for rapid reaction in chlorine residual decay after chlorination, which comprises the following steps of: 1) adding sodium hypochlorite into water needing disinfection to prepare disinfected water with the total initial residual chlorine concentration C0 of 1.1mg/L-1.7mg/L; 2) taking the disinfected water in step 1), measuring the residual chlorine concentration C at different time t, fitting data by a formulary parallel first-order reaction model of C=xC0e<-kft> +(1-x)C0e<-kst>, fitting three parameters of x, kf and ks in a least squares method to obtain x, kf and ks, and multiplying x, C0 and then an adjustment coefficient 1.10-1.20 to obtain the chlorine demand for the rapid reaction. The method disclosed by the invention has the characteristics of low cost and safety, and at the same time the method is simple, has strong operability and good controllability, and is easy for expansion and industrial production. The chlorine demand for the rapid reaction can be determined rapidly and accurately by the method disclosed by the invention, so that accurate chlorination is carried out according to the chlorine demand for the rapid reaction. |
