Conch Cement Fenghuang Mountain Cement Plant is located in Qishan, Shanxi Province. It has a 9MW pure low temperature waste heat power generation system and uses deep well water as circulating cooling water. The water quality standard is seriously exceeded, which causes serious fouling on the condenser. At the same time, the circulating wastewater discharge is forbidden. Therefore, it is necessary to construct a set of circulating cooling water treatment facilities to improve the quality of the circulating water and achieve ZLD target.
