Description

Urban rainwater collecting filter

Technical Field

The utility model relates to the technical field of filters, in particular to a city rainwater collecting filter.

Background

Rainwater collection systems are becoming an important sustainable water resource management solution when cities face problems of scarce water resources and environmental pollution. Conventional stormwater collection systems typically include stormwater collection, storage and utilization processes, but in practice, the direct collection and utilization of stormwater can present water quality problems due to impurities and contaminants in the stormwater. Therefore, urban rainwater collection filters are widely studied and applied as a key technology to ensure that collected rainwater can reach applicable standards and be safely used in different fields.

The stormwater is led via a pipe to a storage facility and then subjected to preliminary treatment via a filter. However, the existing filter at present usually only adopts a simple filtering structure, only can perform preliminary filtration to a limited extent, and the effect is not satisfactory, meaning that most impurities, particles and pollutants still possibly enter the storage system, so that the water quality and the stability of the system for subsequent utilization are affected.
