Rainwater utilization, did not pass before the proper disposal (such as sterilization, etc.), usually do not advocate for the human touch instead of water (such as clean water, irrigation, flowers, etc.) based. Can also be collected rainwater down, after disposal and storage of process water pump will be promoted to the top floor of the tower rainwater for toilet flushing use. In addition, as with human touch of water, still water supply. In addition to the street as rain water flushing toilet, but also other water such as cooling water, fire water, wash water, flowers and irrigation, water scene, road clearing, etc. can be used, in addition, can also be disinfected after disposal for residents to drink . Usually use rainwater soaked reserving places usually parks, oasis, yard, parking, construction material, such as playgrounds and road. There are many sophisticated urban rainwater using examples. London century Dome collect rainwater use system. Britain in 2000 built a century Dome in London demonstration project, the project area is 100,000 m2, equivalent to the size of 12 football fields. Designers from the dome cover to collect rainwater in a reed bed for disposal, the disposal process consists of two reed beds (each plot for the appearance of 250m2) and a pond (its volume of 300m3), the use of rainwater and ecological organic linked to the performance of energy-saving voice reconcile man and nature, getting high, making rainwater recycling are increasingly being focused on. Today can be found on the Internet can be a lot of associated equipment manufacturers, but not many know the real rainwater recycling system. We use rainwater sponge Shenzhen Technology Co., after four years of casting international quality, specialized in the production and sale of rainwater collection system, drainage system equipment. The company doing PP plastic rainwater collection module, drainage module, rainwater infiltration module, pp rainwater collection tank, plants fixed module, the drainage board. PP rain module has the following features: rainwater tanks to collect rainwater from multiple modules. 1 capacity: PP rain module in standard modular design, can be designed into a variety of shapes and sizes according to the project. From a fundamental change in the conventional basin subsidence, cracking, leakage and other problems. 2, rainwater collection simple and quick: PP rainwater module to collect rainwater from roofs, gardens, lawns, paved areas and driveways to increase water storage and supply capacity. Owns 95% of the reservoir porosity rate, and more than 6 tons of compressive strength. . 3, saving time and effort; PP module rainwater quickly assembled without tools, dramatically reducing the use of construction machinery and construction strength. Installed in the ground, set in green on demand, roads, squares, parking lots, playgrounds underground, do not take up floor space, and will not affect the landscape effect. 4 Water storage capability: rain rain PP module before entering through the abandoned flow, filtration, water module is maintained under optimal conditions, and there is enough space for aerobic activities. This prevents stagnant due to rain and water quality impacts of anaerobic bacteria. 5, environmentally friendly products: 100% recycled material (polypropylene) manufacturing, safety and no pollution. 6, garden reservoirs: PP module can create maintenance of rainwater storage reservoirs, year round to collect rainwater for watering landscaping provide a lot of water. Comparison of traditional irrigation methods, can save a lot of money on. Material: 100% recycled environmentally friendly PP (polypropylene) gap: 50 to 70 spaces chemical and biological resistance: from soil, algae, soil microbes, bacteria and other items affecting asphalt temperature: -30 ℃ to 120 ℃ Compressive strength: 151.28 T / m water flow rate: 105Ltrs / min
