摘要：

A new enviromnent-friendly wastewater treatment technology was developed for the treatment of mixed acid drainage containing fluorine, The ordinary wastewater system using "slaked lime" is ineffective at removing fluorine; besides, it cannot decompose "hard-type surfactants" in the wastewater, so the amount of generated sludge and the quality of treated wastewater are not at the satisfactory level. This newly developed wastewater system uses microorganisms and calcium carbonate to treat the industrial wastewater that contains strong chemicals such as acids, bases, and hydrogen peroxide, By changing the structure and construction of the treatment tanks, it is possible to treat calcium carbonate and microorganisms at the same time and decompose hard-type surfactants, This greatly contributes to improved water quality, saves resources, and reduces greenhouse gas emissions to one third those of the old system.
