PROBLEM TO BE SOLVED: To preferably recover metal sludge by separation from a treatment liquid even when a treatment liquid contains metal sludge in a larger amount than conventional.SOLUTION: A recovery system 3, which recovers metal sludge M contained in a liquid LO by separation from the liquid LO, comprises: at least one flat-tabular filter plate 34, provided so that the rear end part may be located below the discharge opening 32a of the liquid LO and having a plurality of slits 34a; and a first recovery basket 35 in mesh form provided below the front end part of the filter plate 34. The filter plate 34 is inclined at an inclination angle α to be located gradually downward from the rear end part to the front end part, and each slit 34a is formed in a shape of spreading to the lower side.SELECTED DRAWING: Figure 2 【課題】従来に比べ、多量の金属スラッジが処理液中に含まれる場合であっても、好適に金属スラッジを処理液から分離して回収する。【解決手段】回収装置３は、処理液Ｌ０中に含まれた金属スラッジＭを処理液Ｌ０から分離して回収するものであり、処理液Ｌ０の吐出口３２ａの下方に後端部が位置するように設けられるとともに、複数のスリット３４ａを有する少なくとも１つの平板状のフィルター板３４と、フィルター板３４の前端部の下方に設けられたメッシュ状の第一回収かご３５とを備える。フィルター板３４は、後端部から前端部に向かうに連れて次第に下方に位置するように傾斜角度αで傾斜しており、各スリット３４ａは、下側に向かって広がる形状に形成されている。【選択図】図２
