Description

High-efficiency swirl-flow filter rainwater barrel with automatic solid-liquid separation function

technical field

The utility model belongs to the technical field of rainwater reuse, in particular to a high-efficiency vortex-flow filter rainwater barrel with the function of automatic separation of solid and liquid.

Background technique

Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, filters, and purifies water, and "releases" the stored water and uses it when necessary.

With the development of urbanization, the accumulation of pollutants makes the pavement rainwater hold a large amount of pollutants. Some road runoff studies have shown that the pollution load in the initial 30% rainwater runoff accounts for 70% of the entire rainfall pollution. Therefore , The interception and treatment of initial rainwater can effectively control the water pollution caused by runoff. At present, there are different measures for rainwater pollution treatment at home and abroad. Most of the foreign countries directly collect rainwater for reuse. Domestically, the initial rainwater is directly introduced into the sewage treatment plant, ignoring the limited decontamination capacity of the sewage treatment plant. Disposal Discharge directly into natural water bodies. Therefore, it is necessary to treat the rainwater in the early stage of waste flow, and develop a rainwater waste flow collection and interception treatment system that can make up for these deficiencies. The rainwater at the beginning of the rainfall is diverted to the sewage pipes, and the rainwater with a lesser degree of pollution in the later stage of the rainfall is pre-treated and intercepted. Sand, gravel and other particulate impurities in the water, as well as a large number of pollutants, can be recycled and reused after repeated filtration and purification, and the purified and filtered rainwater can be used to maintain the lawn and improve the utilization rate of water resources.

The rainwater filtering devices in the prior art have many disadvantages, such as the designed volume is too large or the designed volume is too small; If the initial rainwater stays for too long, sand, gravel and other particulate impurities and a large number of pollutants are easy to settle, which can easily cause blockage of the device, which is not conducive to the normal use of the device.
