Description

Technical Field

[0001] The utility model relates to the field of environmental protection devices, and particularly relates to a rainwater recycling system for factory areas. Background Art

[0002] Rainwater, as a precious natural resource, reasonable recycling can effectively alleviate the problem of water resource shortage. Especially in arid or semi-arid regions, it is even more necessary. By collecting and treating rainwater, the pressure on the urban drainage system can be reduced, and the risk of urban waterlogging caused by heavy rain can be reduced, thus protecting the safety of public facilities. In addition, the recycled rainwater can be used for various purposes such as greening irrigation, cleaning, and makeup water for cooling systems in the factory area, which helps to reduce the water consumption cost of enterprises and achieve resource recycling. The quality of natural rainwater is relatively good. In the factory area, if it is recycled and reused, it has important environmental protection benefits. If 75% of the storage capacity of the rainwater pool is recycled each time, and the unit price is calculated at 3 yuan per ton of the raw water after pretreatment at present, it is estimated that the water saving cost can be 22,500 yuan each time; calculated according to 10 times of collection and recycling in the rainy season, it is estimated that the annual cost can be saved by 225,000 yuan. In the prior art, the rainwater recycling systems of most factory areas are still imperfect, with low recovery rates and unable to achieve the recycling of water resources.

The unqualified rainwater lifting pool and the accident pool of the factory area share a sewage treatment pipeline, which can improve the utilization efficiency of the pipeline.

[0012] The technical solution of the present utility model further includes that a regulating tank is provided on the pipeline at the water inlet end of the sewage treatment device, and valves are provided at the water inlet and outlet ends of the regulating tank. The regulating tank mainly realizes the functions of flow rate equalization, water quality homogenization, emergency storage or addition of water treatment agents and providing a reaction space before sewage treatment.

[0013] As a preference, the technical solution of the present utility model further includes that a ceramic membrane filter is provided inside the sewage treatment device.

[0014] Furthermore, the technical solution of the present utility model further includes that an activated carbon adsorption layer is provided at the water outlet end of the ceramic membrane filter.
