<p>PURPOSE:To utilize a waste water availably and bring a economical deodorizing effect as a system by utilizing a washing waste liquid from a deodorizing apparatus using an oxidizing agent in pasturizing the secondary treated water or the like. CONSTITUTION:In the water treating installation such as a sewage, an excretion treating plant or the like, from a standpoint of an environment sanitation, a deodorizing apparatus using an oxidizing substance such as hypochlorite or chlorine gas is installed in many cases. Then, the washing waste liquid containing said oxidizing substance from this deodorizing apparatus is subjected to a biological treatment and a solid-liquid separating treatment and, thereafter, mixed into the secondary treated water. Thereby, the residual chlorine in the washing waste liquid pasturizes the secondary treated water. As described above, the utilization efficiency of chemicals is enhanced by the water treating system with good efficiency.</p> |
