An integrated rainwater recovery, storage and transfer system and method thereof

Abstract

The invention discloses an integrated rainwater recycling-storage-dispatching system and method. The system comprises a filterer, a down-seep well, a water storage tank, an overflow water tank and a purifying device. A filtering frame body is arranged in the filterer, and comprises a rack body, a support fixing block and a first baffle. Water level detecting devices are arranged in both the water storage tank and the overflow water tank. A buffering device and a submerged pump are arranged at the bottom of the water storage tank. The construction method comprises the steps of S1, excavating a foundation pit, S2, conducting the construction of the water storage tank and the overflow water tank, S3, conducting the construction of the submerged pump and the buffering device, S4, establishing the down-seep well, S5, conducting the paving of a first down-seep pipe and a second down-seep pipe, S6, installing the filterer and the purifying device. The integrated rainwater recycling-storage-dispatching system and method have the advantages of being simple in structure, strong in practical application, and convenient to install. After the installation of the water storage tank, the other equipment are installed directly on the top surface of the water storage tank without any problem of elevation differences, therefore the trouble of pipe matching is saved, and the whole construction is made easier.

Description

technical field [0001] The invention relates to an integrated rainwater recovery, storage and regulation system and a method thereof. Background technique [0002] Sponge city is a new concept of urban construction proposed by the state. As a path to restore urban water ecology, "sponge city" has the functions of infiltration, stagnation, storage, purification, use and drainage when it rains, and can realize water recycling. And recycling, saving water, solving the increasingly serious ecological crisis of the water environment faced by more and more cities, and minimizing the damage to the original water ecological environment of the city. The construction of a sponge city follows the principles of ecological priority and combines natural methods with artificial measures. On the premise of ensuring the safety of urban drainage and waterlogging, it maximizes the accumulation, infiltration and purification of rainwater in urban areas, and promotes the utilization and utilizat...

Problems solved by technology

[0003] At present, the rainwater system of the sponge city mainly adopts the direct discharge method for drainage. The drainage system is not properly set up according to the rainwater situation. The rainwater that falls to the ground directly enters the water pipe network through the rainwater well. Insufficient drainage capacity, rainwater wells are very easy to block, resulting in high drainage pressure, resulting in waterlogging in many cities; in addition, due to the oil pollution and other heavy metal pollution generated during the use of the road surface, the rainwater will form polluted runoff after being washed away. If it is directly discharged into the rainwater pipe network , will undoubtedly cause water resource pollution, and in some heavily polluted areas, the initial rainwater quality is poor, and it will be directly discharged into river water bodies, which will also cause great pollution to urban water systems
