Sponge City Road Rainwater Integrated Circulation Treatment System

Abstract

The invention discloses a rainwater integrated cycle treatment system for sponge city roads, which comprises a rainwater collection unit, a rainwater treatment unit and a rainwater utilization unit which are connected in sequence. The pool is connected with the water storage module; the initial rainwater abandonment device includes the waste flow pool, and the entrance of the waste flow pool is provided with a permeable partition and a floating plate, and the permeable partition and the floating plate are connected to form an I-shaped structure. There is an opening, the opening is provided with a water baffle, the opening is connected with the municipal sewage pipe network, and sensors are installed on the inner wall of the permeable partition, floating plate, water baffle and the entrance of the waste flow pool; the rainwater utilization unit includes A water storage tank connected to the water storage module, a water pump is arranged in the water storage tank, and the water pump is connected with the spraying control device on the ground, a humidity sensor is set in the soil above the water storage tank, and the humidity sensor is connected with the spraying control device, The pool is also connected to the municipal pipe network through pipe valves.

Description

technical field [0001] The invention belongs to the technical field of sponge city construction and rainwater resource utilization, and in particular relates to a sponge city road rainwater integrated circulation treatment system. Background technique [0002] my country is a country seriously short of water resources. According to statistics, more than 50% of the more than 600 cities in the country are short of water, and nearly 20% of the cities are seriously short of water. In recent years, with the rapid development of urbanization, the area of ​​urban green space has gradually decreased, and most of the green areas, wetlands, ditches and other areas that originally had the function of water conservation have evolved into hardened ground, resulting in cities that can only rely on municipal management in the face of heavy rainfall. Network drainage, resulting in frequent waterlogging disasters and serious runoff pollution; but after the heavy rain, it fell into the predic...

Problems solved by technology

[0004] Chinese patent application 201610605947.4 proposes a sponge city road system and a method for collecting and utilizing rainwater. The main technical solution is that the rainwater on the motorway passes through the perforated station stone and then enters the grit chamber. The rainwater from the sunken green belt flows into the overflow well, and the water in the overflow well enters the water storage tank for storage after passing through the filter wall; when the water in the overflow well overflows the overflow port, the water flows into the municipal In the drainage pipe of the pipe network, but the disadvantage of this method is that it does not consider the problems of the initial rainwater abandonment, road permeable pavement, rainwater counterflow, etc. The practicability is not particularly good, and it is easy to cause secondary pollution to the environment
