Introduction to Rainwater Treatment and Reuse System:

The waste of water resources in our country is very serious, and the scarcity of water resources is also an undeniable fact. How to recycle water resources and reduce water waste has become the top priority. With the increasingly severe contradiction between water supply and demand, more and more countries have recognized the value of rainwater resources and taken many corresponding measures to adapt to local conditions. The increasing demand for energy conservation has led to a growing emphasis on rainwater recycling and reuse. Adopting a rainwater collection system. In line with China's sustainable development strategy. Traditional urban rainwater collection is a process where rainwater falls to the ground and a portion of it infiltrates through the ground to supplement groundwater. Rainwater that cannot infiltrate or cannot infiltrate in time is collected through the ground and flows into rainwater outlets. It is then collected through collection pipes and discharged into rivers or pumped into rivers. With the increase of urbanization, traditional rainwater management models often cause major problems such as urban floods, rainwater runoff pollution, massive loss of rainwater resources, and ecological environment damage. Therefore, currently, the market urgently needs a new type of energy-saving and environmentally friendly rainwater collection system.

Scientific, rational, and efficient utilization of rainwater resources can not only alleviate urban water shortage, but also conserve and protect water resources, control urban soil erosion, reduce waterlogging, control the funnel effect and settlement caused by urban groundwater overexploitation, reduce water pollution, and improve urban ecological environment. The benefits of implementing urban rainwater harvesting and utilization have become a common consensus among people. At present, the utilization of rainwater has received increasing attention from the government, and most cities have made relevant regulations on the collection and utilization of rainwater. Rainwater has a wide range of uses, including greening irrigation, flushing toilets, cleaning roads, washing clothes, some industrial water, air conditioning cooling water, and more. The utilization of rainwater will alleviate the shortage of water resources and promote the sustainable development of the local economy.

Rainwater collection refers to the process where rainwater falls onto the roof and ground, and a portion of it infiltrates through the ground to supplement groundwater. Rainwater that cannot infiltrate or cannot infiltrate in time converges with the ground through the roof and enters the municipal rainwater pipe network. After collecting rainwater, the collected rainwater is treated according to different needs to meet the design requirements.

The underground integrated rainwater treatment and reuse equipment provided by our company consists of a sewage interception and filtration system, a water storage system, a rainwater purification system, and a constant pressure water supply system. The above-mentioned products were first widely used in developed Western countries, and with the increasing emphasis on water resource management in China, they have now been introduced to China.

Rainwater treatment/reuse process:

Rainwater enters the rainwater well through the rainwater pipe network and is collected. After being treated by the initial rainwater interception/runoff device, the highly polluted rainwater in the early stage enters the municipal rainwater pipe network, and the intercepted/runoff rainwater enters the rainwater reservoir. Rainwater is stored in the reservoir and when reused, the buried integrated rainwater treatment/reuse device (equipment) is turned on. The rainwater in the reservoir is filtered and stored in the clean water tank, and then lifted to the backup water point through a variable frequency stabilized water supply pump set. Configuration between various devices in the systemPLCThe linkage control system enables automatic switching of operations between devices based on collection volume and usage.

Advantages of Underground Integrated Rainwater Treatment/Reuse Device

1Not affecting the landscape, fully buried installation, small footprint, with only manholes and inspection holes left on the ground. The carbon steel shell with epoxy asphalt marine anti-corrosion paint internal and external anti-corrosion technology has sufficient support strength and anti-corrosion properties, and can be planted with greenery on top.

2The multi-media filtration equipment inside the device can meet customers' different needs for effluent quality.

3The operating system is programmed, and property personnel can quickly master the programmed operation process through simple training.

4The purification part of the system adopts multi-media purification, which has significant advantages such as strong interception and deodorization ability, stable effluent quality, long purification cycle, and low backwash water consumption.

5The system comes with a clean water tank and a variable frequency stabilized water supply pump set, which meets the requirements of users for constant pressure water supply for greening irrigation or toilet flushing, and saves users' related civil engineering investment.
