Background Art

[0002] With the continuous improvement of the social market economy, the economic and technological level and modernization construction have gradually accelerated, the scale of cities has continued to expand, and the pressure on urban drainage systems has become increasingly greater. There are misconnections and mixed connections in the rainwater and sewage pipe networks in old urban areas, and the phenomenon of inflow and infiltration in the pipe networks has continued to increase, resulting in long-term economic losses and increased water pollution.
