A processing apparatus for treating acid mine wastewater using an activated carbon-loaded microorganism includes a purifying container, a reducing body and an oxygen consumption body. By arranging a fuel gas body, a bottom of a cover disc is in threaded connection with a top of a top pipe after red phosphorus in a bottom cylinder is ignited, air in a feeding chamber enters into the bottom cylinder through gas ports, the oxygen in the air is consumed as the red phosphorus continues to burn, such that an interior of a reaction bin is in an oxygen-free environment, for ease of the microorganism performing the biological reduction reaction on the acid mine wastewater.

A system for a sandy soil landfill solid waste polluted river channel, includes a ground water interception and diversion system and a river channel ecological remediation system. The ground water interception and diversion system includes a water intake well arranged upstream of ground water in a landfill area, a buffer pool communicated with the water intake well, and a wastewater treatment system communicated with the buffer pool. The water intake well, the buffer pool, and the wastewater treatment system are communicated through a wastewater pipe. An electric wastewater valve and a variable frequency water pump are arranged on the wastewater pipe in sequence. The river channel ecological remediation system includes an impermeable layer arranged at a bottom of a river channel and ecological bank protections arranged on both sides of a river channel slope.
