Abstract:

Drilling wastewater treatment by coagulation would make pollutants in water collect in the sediment. This thesis has summed up the leaching experiments of two kinds of sediments at different pH values and temperatures, pointed out there are few pollution in the leaching liquids of sediments because of the effect of the coagulants, and further offered a suggestion for decreasing polution of sediments.
