Located in Deqing County, Zhejiang Province, Xinshi Ancient Town is the origin of the largest water transportation terminal on the Beijing Hangzhou Grand Canal, a world cultural heritage site, with a history of over 1700 years. August 15th is the first National Ecological Day. On this day, prosecutors from the Deqing County Procuratorate walked along the green banks of the Dayun River in the early morning to inspect the Grand Canal and the ecological environment along the banks. The "Yixin for the Public" volunteers who went together witnessed the changes of the Grand Canal in the past two years... not only protecting the Grand Canal, but in recent years, the procuratorial organs of Huzhou City have been constantly walking on the path of protecting the green waters and mountains. The answer to unwavering ecological protection is to solve the problem of illegal pollution prevention and control at the source. "The factory environment is cleaner and cleaner, the operation of treatment equipment is more standardized, and the regulatory system is smoother, I cannot help but sigh that the "bottleneck" problem of township sewage treatment plants is gradually being fundamentally solved. This reform achievement is attributed to a criminal case of adding "COD remover" to interfere with automatic monitoring facilities for environmental pollution handled by the Huzhou City Procuratorate a year ago. Changxing Environmental Protection Technology Co., Ltd. was originally a key pollutant discharge unit determined by the Ecological Environment Bureau of Huzhou City, but it has purchased "COD remover" seven times and added it to the sewage treatment end, interfering with automatic monitoring facilities and avoiding online COD monitoring. After prosecution by the procuratorial organs, the court ultimately sentenced the defendant unit to a fine of 200000 yuan for the crime of environmental pollution. The defendant, Xia, was sentenced to one year in prison, suspended for one year and six months, and fined 20000 yuan. In response to the issues exposed in the case of sewage treatment plants' pollution control and anti pollution measures, as well as the continuous high administrative penalties and fines that have not effectively stopped illegal discharge of pollutants, the prosecutor conducted a systematic research on sewage treatment plants within the scope of Huzhou City and found that there are deep-seated problems such as unsmooth management systems in the operation of township sewage treatment plants. In the first half of this year, the procuratorial organs of Huzhou City proposed to the local party committee and government suggestions for standardized, scientific operation, and supervision of sewage treatment plants in the city, which received high attention and promoted the transformation and reshaping of the system and mechanism of sewage treatment plants in the city. Nowadays, four township sewage treatment plants with significant management risks in Huzhou City have been acquired by the government and implemented a "civilian to public" operation. Urban industrial sewage treatment plants have begun research and construction. The procuratorial organs of Huzhou City have solved the problem from the source and institutional mechanisms, truly achieving effective prevention of illegal discharge from township sewage treatment plants. Both the original and the source should be cleared. In the past two years, the procuratorial organs of Huzhou City have urged the closure and rectification of 27 polluting enterprises, and cleaned up over 770000 tons of solid waste, hazardous waste, and household waste. This is also a microcosm of the integration of procuratorial power into social governance by the procuratorial organs of Huzhou City. The detective story behind "Deep Blue One" is that in the summer of Anji County, the mountains are green, the rivers are clear, and the air is fresh. At sunset, across the country
