Sewage treatment control based on adaptive fuzzy algorithm

China is one of the countries with severe water shortage. Water resource per capita is one quarter of the world average. China's river systems are subject to different degrees of pollution. Waste water is generated in the control design water pH monitoring and acid-base neutralization process. The paper is mainly developed to introduce fuzzy adaptive PID control into S7-300PLC and establish a closed loop PID control system. The simulation results show that the fuzzy control system mentioned in this paper is much better than the conventional PID control system. The study solves key technical problems in the wastewater treatment process so as to create economic benefits.
