Among the six key tasks for improving rural habitat, the situation of promoting rural sewage treatment is more complex. China's rural areas are vast and characterized by different natural conditions. Even in the same township, different villages have different population sizes, topography, environmental capacity and levels of economic development, resulting in different water quantity, water quality and discharge characteristics of domestic sewage. Rural domestic sewage treatment should adhere to village suitability. On the issue of funding for the operation and maintenance of facilities, villages with better conditions can implement a system of payment by farmers for sewage treatment, villages with a better collective economy can use village self-financing, and local governments can also improve the way of self-financing in rural areas. By attracting social...

In order to make pollution control facilities work and to continuously improve the level of treatment, owners, operators and regulators must do their best not only to maintain the bottom line of emission standards, but also strive to minimize emissions. Only in this way can pollution control facilities be used, and blue water will come closer and closer to us. Some experts have done research that the quality of operation of sewage treatment plants comes from three aspects, firstly, the construction standards and management level, secondly, the law-abidingness and sense of responsibility of the operators, and thirdly, the supervision by the government. Judging from the current situation, the most common problem is still in the operation of enterprises. However, it seems unfair if boards that exceed the standards are put on the enterprises...

China has always attached great importance to the impact of artificial weather influence on the environment. The results of many tests and analyses have shown that silver iodide catalysts have no adverse effects on the ecological environment. Since 2003, Beijing has conducted artificial rain augmentation in the Miyun Reservoir and Guanting Reservoir areas every summer and has detected silver ions in the water of the reservoirs. The results showed that the average concentration of silver ions in the reservoirs was 0.64 micrograms per liter, far below the national standard of 50 micrograms per liter stipulated in the Hygienic Standard for Drinking Water for Life (GB5749-2006). The operation of artificial weather influence is localized, the use of catalyst is minimal, and the operation time and influence range are limited.
