Abstract
China is rich in mineral resources, among which the proven reserves of phosphate rock
resources rank the third in the world. Guizhou is one of the main phosphate rock resources
mining areas in China, and many phosphate rock mining enterprises are distributed along the
Wujiang River. Industrial phosphate mining will produce a lot of wastewater, and phosphate
wastewater contains a lot of phosphide, its main components P

ion is the main
cause of water eutrophication, the increase of phosphorus content in water will cause serious
damage to the ecological environment. In this paper, the phosphorus removal control system
of phosphate rock wastewater is studied, which provides technical support for the stable
phosphorus removal of phosphate rock wastewater. The main contents include:
(1)According to the analysis of the sewage phosphorus removal process, the overall
scheme of the control system is designed, the main control objectives and functions of the
sewage phosphorus removal control system are determined, and the pump, valve, pipeline and
other equipment are selected according to the design requirements. In order to fully treat the
phosphide in the phosphate rock wastewater, the structure optimization design of the reaction
flocculation tank in the scheme is carried out, and the feasibility of the design structure of the
reaction flocculation tank is verified through the simulation experiment analysis.

Aiming to the characteristics of wastewater phosphorus removal process, such as
non-linear, lag and time-varying, the research method of combining control technology with
PLC controller is proposed. The control model is simulated and analyzed by Simulink in
MATLAB to ensure the reliability and stability of the system. In the control technology, fuzzy
control technology, PID control technology and adaptive fuzzy PID control technology are
adopted. Through simulation and experimental comparison, the adaptive fuzzy PID control
technology is finally selected. A set of automatic control system for phosphorus removal from
phosphate rock wastewater based on Adaptive Fuzzy PID algorithm is designed and
developed. Through the analysis of historical data and empirical data, the parameters in the
fuzzy PID controller are set The membership function and the k

parameters in the fuzzy

performance and meet the requirements of sewage treatment automatic control system for
efficient sewage treatment.

treatment, the sewage treatment control system is developed. The system adopts the
combination of man-machine interface control in the control room and remote host computer
interface control. The control room is controlled by MCGS touch screen on the control
cabinet, and the remote control adopts two host computers controlled by Kingview
configuration. The field test and application show that the control system has good stability,
can treat sewage stably, accurately and efficiently, and can reduce the dosage of phosphorus
removal agent by about 30%.
