Full-automatic rainwater ecological purification utilization device

Abstract

The invention provides a full-automatic rainwater ecological purification utilization device, and relates to the field of rainwater purification treatment. Rainwater of different periods can be effectively purified and utilized. According to the technical scheme, the full-automatic rainwater ecological purification utilization device comprises a water supply system and a purification system. The water supply system comprises a water tank, a horizontally-arranged module sliding table, a slidable nozzle arranged on the module sliding table and a pipeline for connecting the water tank with the nozzle. The purification system comprises a box body arranged under the module sliding table. A left purification unit and a right purification unit are arranged inside the box body. Each purification unit is sequentially filled with a gravel layer, an activated carbon layer, a coarse sand layer, a fine sand layer and a soil layer from bottom to top, wherein each layer is integrally provided with a sampling pipe, and vegetation is planted on the soil layer. The thicknesses of the gravel layer, the activated carbon layer, the coarse sand layer and the fine sand layer of one purification unit are gradually decreased, the thicknesses of the gravel layer, the activated carbon layer, the coarse sand layer and the fine sand layer of the other purification unit are gradually increased, and the bottoms of the two purification units are each provided with a water outlet blind pipe communicated with the external world.

Description

technical field [0001] The invention relates to the field of rainwater purification and treatment, in particular to a fully automatic rainwater ecological purification and utilization device. Background technique [0002] China is a country that lacks water resources. Rainwater is a kind of water resource, which should be collected and used to reduce water demand. However, during the rainfall process, pollutants such as dust in the air are brought into the rainwater. In addition, during the rainwater confluence process, The impact of rainwater on roads, roofs, etc., has led to a further increase in the concentration of rainwater pollutants after confluence, especially in the initial rainwater, which is rich in suspended particles and other harmful substances such as heavy metals. Rainwater is polluted to varying degrees. For treatment, on the one hand, the diameter flows into the water body, which will pollute rivers, lakes and other water bodies to a certain extent. On the ...

[0002] China is a country that lacks water resources. Rainwater is a kind of water resource, which should be collected and used to reduce water demand. However, during the rainfall process, pollutants such as dust in the air are brought into the rainwater. In addition, during the rainwater confluence process, The impact of rainwater on roads, roofs, etc., has led to a further increase in the concentration of rainwater pollutants after confluence, especially in the initial rainwater, which is rich in suspended particles and other harmful substances such as heavy metals. Rainwater is polluted to varying degrees. For treatment, on the one hand, the diameter flows into the water body, which will pollute rivers, lakes and other water bodies to a certain extent. On the other hand, the polluted rainwater cannot be used directly. It is necessary to pass the rainwater through the purification device first, and then use the rainwater after it has been purified to a qualified level.
