A roof rainwater treatment system and construction method

Abstract

The invention discloses a rainwater treatment system and a rainwater treatment construction method for a house roof. The rainwater treatment system comprises a rainwater collection pipe network, a rainwater stand pipe, a rotational flow filter device, a rainwater collection pool and rainwater fetching systems. The rainwater collection pipe network comprises flashings and a rainwater collection tank. The rainwater fetching systems are internally provided with rainwater fetching pipes and pressure control pumps. The rainwater treatment construction method comprises the steps of (a), paving of the flashings; (b), mounting of the rainwater collection tank on the roof; (c), mounting of the rainwater stand pipe on a wall; (d), excavation of a foundation pit; (e), mounting of the rotational flow filter device in the foundation pit; (f), arrangement of the rainwater collection pool; and (g), mounting of the rainwater fetching systems into the rainwater collection pool. The rainwater treatment system and the rainwater treatment construction method are used for collecting, filtering, purifying, storing and utilizing rainwater on the roof and can be used for an undrinkable water environment, the resource utilization efficiency of the rainwater is improved, waste is turned into wealth, water resource shortage is relieved, the construction steps are simple and low in difficulty, the construction quality is easy to control, the construction cost is low, and the number of involved construction equipment is small.

Description

technical field [0001] The invention belongs to the technical field of water resource utilization, and in particular relates to a house roof rainwater treatment system and a construction method. Background technique [0002] With the advancement of urbanization, the increase of ground hardening has changed the original hydrological characteristics, resulting in increased rainwater runoff, frequent water accumulation on the road surface, and frequent large-scale water accumulation in some cities. The drop in groundwater level has intensified. In addition, the problem of water shortage in my country's cities is becoming more and more serious. The resource-based water shortage in the northern region and the water quality-based water shortage in the southern region. In this environment, the government proposed the goal of building a "sponge city" and supported it in various aspects such as policy and finance. [0003] Sponge city, as the name suggests, is like a sponge. During...
