Rainwater regulation, storage and reuse system in saline and alkaline area

Abstract

The invention relates to a rainwater regulation, storage and reuse system in a saline and alkaline area, and relates to the technical field of rainwater treatment. The rainwater regulation, storage and reuse system mainly includes a rainwater inlet pipe, a rainwater regulation pool, a rainwater regulation and storage pool, a clean water pool and a rainwater reuse pipe, a filter screen is arrangedat one end of the rainwater inlet pipe, and connected to the pool top of the rainwater regulation pool, an overflow port is formed in the side wall of the rainwater regulation pool to be connected with the rainwater regulation and storage pool, an initial rainwater drainage pipe and a mud drainage pipe are arranged at the pool bottom, a water distribution trough is formed in the rainwater regulation and storage pool, the mud drainage pipe is arranged at the bottom of the rainwater regulation and storage pool, a filter screen is arranged at one end of a rainwater outlet pipe, a submersible pumpis arranged on the clean water pool to be connected with the rainwater reuse pipe, and the rainwater regulation pool, the rainwater regulation and storage pool and the clean water pool adopt multi-layer salt prevention anti-corrosion materials correspondingly. According to the rainwater regulation, storage and reuse system, saline and alkaline infiltration and corrosion of rainwater regulation, storage and reuse facilities in the in a saline and alkaline area can be effectively avoided, initial rainwater abandonment is automatically completed by arranging the regulation pool, the inner spaceof the rainwater regulation and storage pool is fully used for completing treatment and purification of rainwater, and economical and high-efficiency utilization of the rainwater in the saline and alkaline area is finally achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, and in particular to a rainwater storage and reuse system in saline-alkali areas. Background technique [0002] Water is the source of human life. It is not only necessary for human survival, but also widely used in agriculture, manufacturing, mining, energy production, etc. Therefore, in today's increasingly scarce water resources, we must use the vision of sustainable development to protect water resources. Utilization of urban rainwater is an emerging field with good market prospects. In the case of serious shortage of water resources, active development and utilization of water resources can be used as one of the important water sources of the city, providing an effective solution for the long-term sustainable development of water resources. way.

AI Technical Summary

Problems solved by technology

[0003] Land salinization has become a global hazard. Soil salinization in saline-alkaline areas causes high salt content in rainwater runoff, which poses certain difficulties for its regulation, storage and reuse

The existing rainwater storage and reuse technology has not taken high salinity factors into consideration. If it is directly applied to the rainwater storage and reuse in saline-alkaline areas, it will inevitably result in low efficiency of rainwater storage and utilization, and greatly shorten the rainwater storage and reuse facilities. life, increasing its operating costs

To sum up, the technologies suitable for rainwater storage and reuse in saline-alkaline areas are very scarce at present, and the development of technologies suitable for rainwater storage and utilization in saline-alkali areas is particularly important for the economical and efficient use of rainwater resources
