Tin-containing sludge treatment method

The invention relates to a tin-containing sludge treatment method which includes the steps: mixing tin-containing sludge and pure water to obtain slurry; performing solid-liquid separation on the slurry to obtain filter liquid and a solid-phase material; heating the solid-phase material to obtain a tin oxide product; filtering the filter liquid to obtain produced water and filter residues, takingstandard produced water in a the device as pure water to be reused, and selecting matched electroplating solution to return to production or enter an incinerator according to specific circumstances after concentrated solution reaches to a certain concentration. The method has the advantages that compared with the prior art, hazardous waste is quantitatively treated, a whole process is low in energy consumption, zero emission is achieved, a technological process is simple, and commercialization is facilitated. 本发明涉及一种含锡污泥的处理方法，其包括如下步骤：将含锡污泥与纯水混合，得到泥浆；将所述泥浆进行固液分离，得到滤液和固相物；将所述固相物进行热处理，得到氧化锡产品；将所述滤液进行过滤后，得到产水和滤渣，将设备中达标的产水
