China has already made progress in this area, with the development of novel sewage treatment technologies and the introduction of advanced technologies from abroad. However, more focus should be placed on technological innovation to address challenges such as substandard effluent quality and high sludge disposal costs.

Enhance Rural Wastewater Treatment

Rural areas in China often lack access to proper wastewater treatment infrastructure. The government should prioritize the development and implementation of innovative solutions specifically for rural communities, such as the construction of rural wastewater treatment stations and the utilization of renewable energy sources for treatment processes.

Improve Sludge Management

Improper sludge disposal is a significant issue in China, with 80% of sludge being improperly dumped. Anaerobic digestion technology, as exemplified by New York City's wastewater management system, can be employed to convert organic waste into valuable by-products like methane and digestate. Capturing methane can also help reduce greenhouse gas emissions. Additionally, leftover digestate can be disinfected and used as fertilizer or soil conditioner.

Address Combined Sewer Overflows (CSOs)

CSOs are a major threat to water quality and reduce the effectiveness of wastewater treatment. Chinese cities should prioritize investing in infrastructure solutions to replace combined sewers with separate municipal storm sewer systems (MS4s). This will help reduce the frequency of overflows and improve the overall water quality.

By implementing these measures, China can effectively improve its waste management infrastructure and make significant progress in treating the increasing volume of wastewater, ultimately reducing water pollution and improving the health and well-being of its citizens.

Reduce agricultural runoff by limiting farming near major rivers

China's economic development has resulted in improved access to water for much of the population. However, millions of people still lack access to safe and easily accessible water. In addition, industrial pollution, rapid urbanization, and inadequate waste management have severely polluted China's surface water and groundwater.

To address these issues, China's Ministry of Ecology and Environment (MEE) has implemented several measures, including the Water Pollution Prevention and Control Action Plan, which sets targets for improving water quality by 2030.

One specific measure that can help reduce water pollution in China is by reducing agricultural runoff through limiting farming near major rivers. Here are some ways to achieve this:

• Implementing buffer zones: Establishing grass or native vegetation buffers between agricultural lands and rivers can help slow down and absorb polluted runoff, stabilize stream banks, curb erosion, and provide habitat for wildlife.
• Improving manure management: Properly managing and storing livestock manure can help prevent it from being washed into nearby waterways. Adding liners to manure lagoons and applying manure only when plants can fully utilize the nutrients can also reduce runoff.
• Promoting conservation tillage: Conservation tillage practices, such as no-till or minimum-till farming, leave crop residue or vegetation on the fields, reducing soil erosion and preventing pollutants from entering water bodies.
• Adopting precision nutrient management: Developing nutrient management plans can help farmers determine the right amount, type, and timing of fertilizer application, reducing excess nutrients that can run off into rivers.
• Restricting livestock access to waterways: Keeping livestock away from water sources and streams can reduce the amount of nutrients and pathogens entering the water, prevent stream bank damage, and improve animal health.
• Collaborating with landowners: Working with landowners, agricultural interest groups, and partner agencies to develop and implement tools and best management practices that reduce polluted runoff from agricultural areas.
• Educating farmers on conservation practices: Providing education and resources to farmers on conservation practices, such as cover cropping, crop rotation, and precision irrigation, can help reduce agricultural runoff and improve water quality.

By implementing these strategies and working collaboratively with relevant stakeholders, China can effectively reduce agricultural runoff and improve the quality of its water sources, contributing to the health and well-being of its citizens and the environment.
