Since the beginning of new era in China, environmental protection requirements have been continuously increasing, imposing higher demands on wastewater treatment various industries. As a significant source pollution, coal chemical industry particularly emphasizes design engineering deodorization systems plants. This paper conducts an in-depth study plants era. Through analysis standards, main devices, and processes plants, as well discussions specific cases, optimization strategies key technical solutions are proposed, aiming to provide beneficial references for implementation similar projects.
