Description

Technical field

[0001] The present invention belongs to the technical field of sewage treatment in the field of environmental technology, in particular to a wastewater treatment village suitable solid-liquid separation feed unit and processing device. Background technique

[0002] With the economic and social development and improve people's living standards, accelerating urbanization process in my country, but the number of rural population, water consumption in rural areas is increasing, large emissions, there are reports of rural sewage discharge is expected to 2020 the total could reach nearly 300 million tons. Population is concentrated in urban areas, sewage is collected and can be transported to the sewage treatment plant for processing, but the way involves a large number of collection pipe network, scattered population live less sewage in rural areas do not apply. Rural decentralized wastewater sources have dispersed, small emissions, large changes in water quality and q...
