摘要
在污水处理控制领域，精准监测水质参数、自动调节处理过程及实现数据远程管理，对提升污水处理效率与质量具有重要意义。传统的污水处理控制方式多依赖人工操作，存在参数调节不及时、处理精度低、数据追溯困难等问题，难以满足现代化污水处理的需求。
基于 STM32F103C8T6 单片机的污水处理控制系统（项目编号：mcuclub-dz-1022），整合了 PH4502C 检测模块、TDS 检测模块、防水式水温 DS18B20 检测模块、水位监测模块 YW_J、按键、OLED 显示模块、WiFi 模块 ESP8266 及语音播报模块 CN-TTS，实现了对污水处理过程的自动化监测、调节与远程管理。系统核心功能包括：通过 PH4502C 检测模块监测当前 PH 值，当 PH 过高或过低时，自动控制加酸或加碱进行中和，同时触发声光报警与语音提醒；通过 TDS 检测当前电解质含量，当电解质大于最大值时，自动投放净化药剂，同步进行声光报警与语音提醒；借助防水式水温 DS18B20 检测模块监测当前水温；通过水位监测模块 YW_J 监测当前水位，当水位过高或过低时，自动进行抽水或进水操作，并伴随声光报警与语音提醒；利用按键可设置各参数阈值、控制外设工作；通过 OLED 显示各项测试数据；通过 WiFi 模块 ESP8266 将监测数据传输至阿里云，电脑端阿里云后台可查看历史数据，并能下发至手机端，手机端可实现参数设置与外设控制功能；通过语音播报模块 CN-TTS 进行语音提醒。
该系统的实现，有效提升了污水处理控制的自动化与智能化水平，通过实时监测、自动调节、远程数据管理及多方式提醒，为污水处理提供了可靠的技术支持，同时为污水处理领域的智能化升级提供了参考，具有较高的实用价值与推广意义。

ABSTRACT
In the field of sewage treatment control, accurately monitoring water quality parameters, automatically regulating the treatment process, and realizing remote data management are of great significance for improving the efficiency and quality of sewage treatment. Traditional sewage treatment control methods mostly rely on manual operations, which have problems such as delayed parameter adjustment, low treatment accuracy, and difficult data traceability, making it difficult to meet the needs of modern sewage treatment.
The sewage treatment control system based on the STM32F103C8T6 microcontroller (Project No.: mcuclub-dz-1022) integrates the PH4502C detection module, TDS detection module, waterproof water temperature DS18B20 detection module, water level monitoring module YW_J, buttons, OLED display module, WiFi module ESP8266, and voice broadcast module CN-TTS, realizing automatic monitoring, regulation, and remote management of the sewage treatment process. The core functions of the system include: monitoring the current PH value through the PH4502C detection module; when the PH is too high or too low, automatically controlling the addition of acid or alkali for neutralization, while triggering sound and light alarms and voice reminders; detecting the current electrolyte content through TDS; when the electrolyte exceeds the maximum value, automatically adding purification agents, along with sound and light alarms and voice reminders; monitoring the current water temperature by means of the waterproof water temperature DS18B20 detection module; monitoring the current water level through the water level monitoring module YW_J; when the water level is too high or too low, automatically performing water pumping or inflow operations, accompanied by sound and light alarms and voice reminders; using buttons to set various parameter thresholds and control the operation of external devices; displaying various test data through the OLED; transmitting monitoring data to Alibaba Cloud through the WiFi module ESP8266, so that the computer-side Alibaba Cloud background can view historical data and send it to the mobile phone side, where parameters can be set and external devices can be controlled; and providing voice reminders through the voice broadcast module CN-TTS.
The implementation of this system has effectively improved the automation and intelligence level of sewage treatment control. Through real-time monitoring, automatic regulation, remote data management, and multi-mode reminders, it provides reliable technical support for sewage treatment. At the same time, it provides a reference for the intelligent upgrading of the sewage treatment field and has high practical value and promotion significance.
