Description

Technical Field

[0001] The utility model relates to the technical field of rainwater purification, in particular to a sponge city rainwater purification pretreatment device. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It refers to a city with good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called a "water-elastic city". It absorbs, stores, infiltrates and purifies water when it rains, and "releases" and utilizes the stored water when needed. Rainwater purification is the process of removing impurities and pollutants from rainwater so that it meets certain water quality standards and can be safely used for various purposes.

[0003] The common rainwater purification pretreatment device has a relatively simple structure and certain functional limitations during installation and use. When rainwater enters the rainwater collection and purification barrel through the rainwater inlet pipe, impurities are accumulated inside at the same time, which makes it inconvenient to treat them uniformly. It is heavy and inconvenient to carry or disassemble it manually, which brings certain adverse effects to people's use process. For this reason, we propose a sponge city rainwater purification pretreatment device. Utility Model Content
