In advance evaluation of occupational disease harmfulness of a wastewater treatment station

The technology of the wastewater treatment station, adopting an automatic drug feeding system, is well developed and up dated. The main factors in the device that will cause occupational diseases consist of poisonous materials, such as sulphide, volatile phenol and hydrochloric acid, and harmful physical elements such as noise. Through the analysis as well as evaluation of occupational disease prevention devices, and of the general layout of the facilities as well as the configurations of the process and equipment, a conclusion is got that the wastewater treatment station basically meets the stipulation of GbZ1-2002 of the sanitation standards of industrial enterprises design.
