Summary:PROBLEM TO BE SOLVED: To provide a decontamination processing method and an on-vehicle decontamination device which enable turbid water generated through decontamination to be efficiently purified on site.SOLUTION: An on-vehicle decontamination device 1 comprises a vehicle 2 and a turbid water processing facility 3 mounted on the vehicle 2 and removes radioactive substances from turbid water containing the same. A decontamination processing method purifies the turbid water generated through decontamination on site using the on-vehicle decontamination device 1. The turbid water processing facility 3 has: a flocculating and solidifying agent supply device 31 which supplies a flocculating and solidifying agent to the turbid water; a flocculating and solidifying tank 32 which mixes the turbid water with the flocculating and solidifying agent; a reaction tank 33 which allows the turbid water to react with the flocculating and solidifying agent; a settlement tank 34 which allows floc formed in the turbid water to settle out; a filtration tank 35 which filters supernatant water produced in the settlement tank 34; and a solid-liquid separation tank 36 which reduces a moisture content of the floc generated in the settlement tank 34. 【課題】除染により発生した濁水を、原位置にて効率的に清浄化させることを可能とした除染処理方法および車載型除染装置を提案する。【解決手段】車両２と、車両２に搭載された濁水処理設備３とを備え、放射性物質を含有する濁水から放射性物質を除去する車載型除染装置１と、この車載型除染装置１を利用して除染により発生した濁水を原位置において清浄化させる除染処理方法であって、濁水処理設備３は、濁水に凝集固化剤を供給する凝集固化剤供給装置３１と、濁水と凝集固化剤とを混合する凝集固化混合槽３２と、濁水と凝集固化剤とを反応させる反応槽３３と、濁水に形成されたフロックを沈降させる沈降槽３４と、沈降槽３４において生成された上澄み水をろ過するろ過槽３５と、沈降槽３４内のフロックの含水率を低下させる固液分離槽３６とを備えている。【選択図】図１
