Waste pyrite area waste rock heap acid wastewater source treatment system and method

The invention relates to the technical field of waste pyrite area treatment, in particular to a waste pyrite area waste rock heap acid wastewater source treatment system and method. Comprising an anti-seepage structure arranged on the surface layer of a waste rock pile, a flood intercepting ditch arranged on the periphery of the waste rock pile, a blocking dam arranged on the downstream side of the waste rock pile and an acid wastewater in-situ treatment pond arranged on the downstream side of the blocking dam. The acid wastewater in-situ treatment pond is located on a diffusion path of an acid wastewater pollution plume formed by underground leakage, and a concentrated water gushing point formed by leakage of the dam body of the blocking dam is communicated with the acid wastewater in-situ treatment pond through a flow guide device. According to the method, the amount of acid wastewater is reduced from the source by cleaning and shunting the outside of the waste rock pile; the acidic wastewater in-situ treat
