What are the processing procedures and precautions for rainwater collection equipment?

The rainwater collection system refers to the entire process of rainwater collection, which can be divided into five stages: collecting rainwater through rainwater collection pipes, intercepting waste water, storing rainwater in PP rainwater collection tanks, filtering and disinfecting, purifying and reusing. The collected rainwater is used for irrigating crops, supplementing groundwater, and can also be used for landscape environment, greening, car washing, road flushing and cooling water supplementation, toilet flushing and other non domestic water uses It can save water resources and greatly alleviate China's water shortage problem

Rainwater recycling system treatment process

The treatment process of the environmentally friendly variable frequency cabinet after rainwater collection is similar to the general water treatment process The difference is that the water quality of rainwater is significantly better than that of ordinary recycled water

The treatment process of rainwater recycling equipment is: roof rainwater - initial waste flow - water storage tank - clean water tank - flushing, greening, etc

2. The main sources of pollutants in the initial abandoned roof rainwater are the decomposition of roof materials, atmospheric sediments, and natural precipitation Due to the initial scouring effect of roof runoff rainwater, the concentration of pollutants in the initial runoff rainwater is high, and the water quality is turbid. As the rainfall continues, once the scouring effect is completed, the water quality of the runoff rainwater will significantly improve. Therefore, measures to discard the initial rainwater should be taken

3. The water storage tank is the main structure of the entire rainwater recovery system. It not only plays a role in collecting rainwater from the roof, but also plays a role in regulating and settling The design rainfall should be reasonably determined based on multiple factors such as the long-term rainfall statistics of the project location, the investment scale of rainwater utilization projects, and water balance It is understood that PP rainwater collection modules are commonly used in water storage tanks, which are simple and environmentally friendly

4. The reuse of clean water in the clean water tank requires a pump lift Small scale rainwater reuse generally uses submersible lift pumps, which can be installed in clear water tanks The water quality requirements for general flushing, greening irrigation, ground flushing, outdoor ornamental water features, etc. are not high The use of rainwater, before proper treatment (such as disinfection, etc.), is generally recommended as a substitute for environmentally friendly anti-seismic bracket water that does not come into contact with the human body (such as sanitary water, watering flowers and trees, etc.) The collected rainwater can also be treated and stored, and then pumped to the water tower on the top floor for toilet flushing In addition, water that comes into contact with people is still supplied by tap water Rainwater can be used not only for flushing street toilets, but also for other purposes such as air conditioning cooling water, firefighting water, car washing water, flower and grass irrigation, landscape water, road cleaning, etc. In addition, it can also be treated and disinfected for residents to drink

Four key points to note for rainwater harvesting system

In recent years, many fresh terms have emerged in daily life, such as e-commerce, intelligent robots, online shopping malls, smartphones, rainwater collection, etc. Rainwater collection is an environmental concept that is close to people's livelihoods, emphasizes science, and conforms to contemporary people's concepts. Simply put, it is a collection of natural rainfall through certain equipment, facilities, and technology, and is processed for irrigation, greening, construction, urban road water use, etc. It can protect the natural ecological environment, recycle water resources, solve the problem of water scarcity, and reduce the pressure of floods and bring people a better and happier life. Do you know what issues must be considered in advance when building and applying rainwater collection systems?

Pay attention to the safety issues of rainwater collection

The application of any technological equipment needs to consider safety issues. It is necessary to ensure the safety and stability of drainage and sewage treatment, which is the foundation for realizing water circulation applications. Therefore, the initial filtration equipment, rainwater interception hanging basket device, PP module reservoir module, and later disinfection and filtration equipment used in the rainwater collection system, such as rainwater filters and ultraviolet disinfectors, should be selected from legitimate equipment to ensure their normal functions can be applied! It is particularly important to note that the PP module is a buried water storage module, which requires some pressure bearing capacity. During the construction process, the location of its burial should be considered, such as under greenery or under parking spaces. The pressure caused by different road conditions varies, and it cannot be fully covered
