た。However, for example, scouring waste liquid, dyeing waste liquid from textile factories, printing waste liquid, etc., which are highly homogenized and dispersed with polyphenol alcohol, sodium hydroxide, surfactants, etc. Colored waste liquids such as dye cleaning waste liquids have extremely dilute concentrations of 0.5 to 1%, and therefore, it is extremely difficult to carry out pollution-free treatment through the above-mentioned solid-liquid separation means. It is difficult to discharge clear water into rivers; for example, as shown in Figure 4,
The waste liquid 2 is supplied to the thickener sedimentation tank area, and a decolorizing agent 3' is added thereto for precipitation.The supernatant liquid waste 4 is further added with a decolorizing agent 3', etc., and then discharged into the river 5, and the colored component 6 is decanted. The residue 8 was formed into a cake using a filter press 7 or the like, and the residue 8 was incinerated and exhausted to a specified level.

河川５に対する最終廃水も実際には着色状態であること
が多いという不具合があった。<Problems to be Solved by the Invention> However, since the extremely dilute colored waste liquid 2 is depolluted by the coagulation-sedimentation method, etc.
The disadvantage is that solid-liquid separation treatment is difficult due to the nature of the waste liquid, and the disadvantage is that sufficient color treatment cannot be performed.
There was also a problem in that the final wastewater for the river 5 was actually often colored.
又、残渣は焼却処理しているために残渣の含有水分が多
いことによる熱効率が悪いという不都合さもあった。Furthermore, since the residue is incinerated, there is a disadvantage that the thermal efficiency is poor due to the large amount of water contained in the residue.
