摘 要
随着环保意识的增强和水质安全的重要性日益凸显，污水处理厂的水质监测系统变得至关重要，为了使污水得到有效处理，本文设计并开发一款基于STM32F103C8T6单片机的污水处理厂水质监测系统。
本系统采用STM32F103C8T6单片机作为主控核心，集成了多种传感器以实现全面监测。通过防水水温监测模块实时监测水温，确保水温在预设的安全范围内；浑浊度监测模块用于检测水中的浑浊度，及时预警潜在的污染问题；PH监测模块则用于监测水体的酸碱度，确保水质符合环保标准；还通过TDS监测模块测量水中的电解质含量，以评估水质的纯净度。当任一监测指标超出预设的安全阈值时，系统会立即触发声光报警，提醒操作人员采取必要的处理措施。并将监测数据通过OLED显示屏实时展示，便于现场监控和管理。系统还集成了按键设置功能，用户可以根据实际需求手动调整各监测指标的阈值，并控制相关设备的开关及模式切换。系统也集成了Esp8266WIFI模块，能够将监测数据实时发送至手机端，实现远程监控和控制功能，进一步提高管理效率。该系统的设计与实现不仅提升了污水处理厂的水质监测能力，确保了水质安全，还通过远程监控功能降低了人工巡检的工作量，提高了整体运营效率。通过本系统的应用，污水处理厂能够更有效地管理水质，减少环境污染，为保护水资源和生态环境提供有力的技术支持。

ABSTRACT
With the enhancement of environmental awareness and the increasing importance of water quality safety, the water quality monitoring system of sewage treatment plant has become crucial. In order to effectively treat sewage, this paper designs and develops a water quality monitoring system of sewage treatment plant based on stm32f103c8t6 MCU.
The system uses stm32f103c8t6 microcontroller as the main control core, and integrates a variety of sensors to achieve comprehensive monitoring. The water temperature is monitored in real time through the waterproof water temperature monitoring module to ensure that the water temperature is within the preset safety range; The turbidity monitoring module is used to detect the turbidity of water and timely warn potential pollution problems; The pH monitoring module is used to monitor the pH of the water body to ensure that the water quality meets the environmental protection standards; The electrolyte content in water is also measured by TDS monitoring module to evaluate the purity of water quality. When any monitoring index exceeds the preset safety threshold, the system will immediately trigger an audible and visual alarm to remind the operator to take necessary treatment measures. The monitoring data is displayed in real time through OLED display screen, which is convenient for on-site monitoring and management. The system also integrates the key setting function. Users can manually adjust the threshold of each monitoring index according to the actual demand, and control the switch and mode switching of related equipment. The system also integrates the esp8266wifi module, which can send the monitoring data to the mobile terminal in real time , realize remote monitoring and control functions, and further improve the management efficiency.The design and implementation of the system not only improves the water quality monitoring ability of the sewage treatment plant and ensures the water quality safety, but also reduces the workload of manual inspection through the remote monitoring function and improves the overall operation efficiency. Through the application of this system, the sewage treatment plant can more effectively manage water quality, reduce environmental pollution, and provide strong technical support for the protection of water resources and ecological environment.
