| In this paper, the principle of sewage treatment processes is analysed and the hasic theory of fuzzy control is introduced. A fuzzy control system of sewage treatment system in a work is designed and realized. The control system combines computer technology with the advanced measuring instruments and fuzzy control theory. By the system automatic control of TOD, PH, temperature and SS of sewage is achieved, It improves the efficiency of sewage treatment and decreases the cost of treatment. This control system is worth spreading for its better stability and robustness. |
