Abstract: Developer-containing waste water is subjected to a multi-stage biological treatment. A waste water treatment apparatus for carrying out a two-stage biological treatment has an adjustment tank for receiving raw waste water and for preliminarily adjusting water quality of the waste water. First and second contact aeration tanks are used to biologically treat the waste water. First and second settling tanks are connected to the first and second contact aeration tanks for separating by sedimentation sludge from the waste water. Specifically, the first settling tank is connected to the second contact aeration tank. Sludge separated from the waste water is returned from the first and second settling tanks to first and second mixing tanks, respectively, and mixed with Bacillus Subtilis Kubota (BSK) and excess household sludge. The mixture is aerated and then transferred to the first and second contact aeration tanks, respectively. The aerated mixture in the first mixing tank is also transferred to the adjustment tank in accordance with the water quality of the raw waste water.

Abstract: An apparatus for waste water treatment, wherein fluorine contained in waste water is treated into a fluoride through a chemical reaction and sludge containing the fluoride is thickened and dehydrated into a sludge cake, has first and second tanks each packed with calcium carbonate mineral. In the first tank, waster water containing fluorine is agitated by air discharged from an air diffuser and caused to react with the calcium carbonate mineral. Through this reaction of the waste water with the calcium carbonate mineral and action of microorganisms on the surface of the calcium carbonate mineral, a pH value and a fluorine concentration of the waste water is adjusted till the pH value and the fluorine concentration fall within their respective predetermined ranges. In the second tank, an aluminum agent is added to the waste water coming from the first tank while the waste water being agitated so that the pH value and the fluorine concentration of the waste water are further adjusted through a chemical reaction of the fluorine with the calcium carbonate mineral and aluminum agent and action of microorganisms propagating on the surface of the mineral so as to fall within their respective target ranges.
