Analysis of Diversified Models for Rural Sewage Treatment

Rural sewage treatment has long been a difficult problem hindering rural development. Because rural areas are widely distributed and their environmental conditions vary greatly, it is necessary to continuously explore and innovate in rural sewage treatment, try diversified rural sewage treatment models adapted to local conditions, and seek new methods to solve rural sewage treatment.

Build artificial ecological wetlands, where sewage goes in and clean water comes out. Water treated through artificial ecological wetlands can be used for direct irrigation. Implement “biological bacteria” microbial fermentation technology. Strengthen the comprehensive treatment of large-scale livestock and poultry farms, promote technologies for the comprehensive utilization and treatment of manure from the livestock and poultry breeding industry, encourage the construction of ecological projects that closely integrate the breeding industry and the planting industry, and make livestock and poultry manure reduced, harmless and resource-based. Local governments should designate breeding areas and restricted (prohibited) breeding areas in a planned way, effectively preventing pollution of water bodies and other areas caused by sewage flowing everywhere. Promote straw biological “reactor” technology. Through “reactor” technology, agricultural waste, livestock and poultry manure, crop straw and other materials are comprehensively utilized through resource-based approaches. Advocate a new model of circular economy development. Through formula fertilization technology, use chemical fertilizers, pesticides and pollution-free biological pesticides scientifically and reasonably. Adopt biological pest control methods and methods such as greatly increasing farmyard manure and planting green manure to reduce pollution of land and water sources. The government can provide certain financial subsidies to users. Try WT-BOX smart treatment technology. Actively explore a new mechanism for coordinated development in which industry promotes agriculture and enterprises lead villages, and look for ways to overcome funding shortages.
