Description
そしてこの目的を達成するため本発明では、オゾン添加空気により金属を含有する生物難分解性排水を分解して分解水を得る分解槽と、微生物により前記分解水から金属を微粒子として還元して金属含有汚泥を含む濃縮水を得る膜分離活性汚泥槽と、前記濃縮水中の汚泥を沈降させて上澄み液を得る沈降分離槽と、前記上澄み液から金属を回収する分離部を備えることを特徴とする排水処理装置としたものであり。これにより所期の目的を達成するものである。
And in order to achieve this object, in the present invention, a decomposition tank for decomposing a biologically difficult-to-decompose wastewater containing metal with ozone-added air to obtain decomposition water; and wherein the membrane separation activated sludge tank to obtain a concentrated water containing containing sludge, the settling tank which precipitated sludge of the concentrate water to obtain a supernatant, further comprising a separating unit for recovering metals from the previous SL supernatant Wastewater treatment equipment. This achieves the intended purpose.
本発明の請求項１記載の排水処理装置は、オゾン添加空気により金属を含有する生物難分解性排水を分解して分解水を得る分解槽と、微生物により前記分解水から金属を微粒子として還元して金属含有汚泥を含む濃縮水を得る膜分離活性汚泥槽と、前記濃縮水中の汚泥を沈降させて上澄み液を得る沈降分離槽と、前記上澄み液から金属を回収する分離部を備えるものである。 The waste water treatment apparatus according to claim 1 of the present invention is a decomposition tank for decomposing biodegradable waste water containing metal by ozone-added air to obtain decomposition water, and reducing metal from the decomposition water as fine particles by microorganisms. in which Te comprises a membrane separation activated sludge tank to obtain a concentrated water containing the metal-containing sludge, the the concentrated sludge was allowed to settle settling tank to obtain a supernatant liquid in water, the separation section for recovering metals from previous SL supernatant is there.
Claims (6)
6. The waste water treatment apparatus according to claim 5, wherein the pore size of the microfiltration membrane used for the separation part is 0.4 μm or less.
