Intelligent urban green land rainwater collection and utilization apparatus

Abstract

The invention discloses an intelligent urban green land rainwater collection and utilization device. Edge stones are arranged at the junction of roads and green land, and disconnection outlets are arranged at every interval of the length of the edge stones. Grille plate, the lower part of the grille plate is provided with a sump, the bottom of the sump is connected to the water inlet end of the gravel filter underdrain through a solenoid valve, and one end of the gravel filter underdrain is connected in turn with an aeration adjustment tank, a hydrolysis acidification tank, a contact oxidation The other end is connected to the sewage collection tank through a solenoid valve, and the first aeration system is installed at the bottom of the aeration regulating tank; the water distribution system is installed at the bottom of the hydrolytic acidification tank, and the water distribution system The upper part is equipped with hydrolysis filler; the bottom of the contact oxidation tank is equipped with the second aeration system, the bottom of the biological aerated filter is equipped with the third aeration system, the first aeration system, the second aeration system and the third aeration system The systems are connected by aeration pipes. The invention realizes the collection, purification, storage and reuse of rainwater.

Description

technical field [0001] The invention relates to the field of rainwater recycling, in particular to an intelligent urban green space rainwater collection and utilization device. Background technique [0002] With the development of urbanization, the problem of lack of urban water resources is becoming more and more serious. However, in daily life, the amount of rainwater accumulated in urban squares and surrounding roads cannot be underestimated. If this part of rainwater can be collected and reused, resources can be saved to a certain extent. [0003] The representative researches on rainwater utilization in foreign countries include Germany, Japan, the United States and other countries. Germany is one of the countries with the most advanced rainwater collection, treatment and utilization technologies in the world. In order to ensure the implementation of rainwater utilization, a complete and practical theoretical and technical system has basically been formed, and relevant...

Problems solved by technology

However, when analyzed from the perspective of urban green space, there is no systematic theoretical guidance, and more of it stays at the level of urban green space. Most green space irrigation fails to utilize rainwater resources.

The traditional concave road surface is easy to cause a large amount of water accumulation. After the rainwater on t
