Pollution-controllable slag block repairing integrated system

The invention discloses a pollution-controllable slag block remediation integrated system, and relates to the technical field of soil remediation treatment.The pollution-controllable slag block remediation integrated system comprises the following treatment stages of the first stage, the soil treatment stage, specifically, after soil is subjected to crushing pretreatment, slag blocks larger than 5 cm enter a slag block remediation system, and soil smaller than 5 cm enters a soil remediation system; stage 2, wastewater treatment stage: the slag blocks are subjected to desliming and cleaning, cleaning wastewater containing less mud is used as process water of a desliming section, and wastewater of the desliming section enters a sewage station to be treated and then is recycled as cleaning water; and 3, sludge treatment, wherein the sludge at the bottoms of the desliming section and the cleaning section enters a sludge pressing machine to be compressed and dewatered and then enters a soil remediation system.
