| description | PROBLEM TO BE SOLVED: To provide a prevention method for food plant drain having glucide such as starch as a main component from increasing viscosity in which the generation of the operation trouble in a drain treatment system is prevented without requiring a specially complicated equipment and the maintenance is easy. SOLUTION: In the prevention method for the food plant drain from increasing viscosity, in a treatment process of the food plant drain before a removing process of a suspended substance, water base liquid of hypochlorite is added to the raw waste water having the glucide as the main component, and the concentration of residual chlorine inside a waste water storage tank is maintained in a range of 0.05-5 mg/l. In the method, the concentration of the residual chlorine is measured by a chlorine concentration detector which is installed inside the storage tank. A control method in which, when the chlorite concentration becomes lower than a predetermined concentration, the water base liquid of the hypochlorite is automatically added to the raw waste water, and when the chlorite concentration becomes higher than the predetermined concentration, the addition of the water base liquid of the hypochlorite is stopped is preferably adopted. |
