Rainwater recycling refers to the collection of rainwater through the aggregate pipe, and in the early stage, rainwater purification devices through the rainwater purification and treatment to achieve compliance with the design and use of the system. Currently most by the interception of sewage hanging basket device, abandoned flow filtering device, water storage system, purification system.
Rainwater recycling flow chart:
Rainwater pipeline --------- interceptor pipeline ------- rainwater discard filter device -------- rainwater automatic filter -------- rainwater storage module ------- disinfection treatment --------- water point
Rainwater recycling is the direct sky hot precipitation Collection storage and utilization. Mature rainwater utilization technology is the collection of water collection - interception - filtration - storage - infiltration - lifting - reuse and control of integrated stereotypes and assembled complete sets of equipment.
Rainwater recycling system features:
Initial rainwater goes through multiple pre-treatment stages to ensure the water quality of the collected rainwater. The water storage module is used for water storage, which effectively ensures the water quality of water storage, and at the same time it does not take up space, and the construction is simple, convenient, more environmentally friendly and safer. Through the pressure control pump and rainwater controller can easily send rainwater to the water point, while the rainwater controller can real-time response to the water level status of the rainwater cistern, so as to reach the water point.
The significance of the rainwater recycling system:
1, to adapt to the needs of economic development
China's water resources are wasted very seriously. The scarcity of water resources is an indisputable fact. How to recycle water resources, reduce the waste of water resources is to become the primary task. With the increasing contradiction between the supply and demand of water resources, more and more countries recognize the value of rainwater resources, and have taken a lot of corresponding measures to carry out comprehensive utilization of rainwater according to local conditions.
2, social development needs
Energy saving calls for more and more, making rainwater recycling and reuse is also more and more attention. Adoption of rainwater collection system. In line with China's sustainable development strategy. Traditional urban rainwater collection is after the rain falls on the ground, part of the ground through the ground infiltration to replenish groundwater, can not infiltrate or too late to infiltrate the rainwater through the ground collection after convergence into the rainwater outlets, and then through the collection of pipeline collection, discharged into the river or through the pump to lift into the river. With the increase of urbanization, the traditional rainwater management mode often causes major problems such as urban flooding, pollution of rainwater runoff, massive loss of rainwater resources and ecological damage. Therefore, at present, the market is in great need of a new type of energy-saving and environmentally friendly rainwater collection system.
3, the demand for scientific and technological development
Currently the domestic market to collect rainwater in the traditional way of reinforced concrete and stainless steel cisterns, the two ways of construction technology is complex, many processes, long construction period, the good cost of manpower and material resources and financial resources are relatively large. The new rainwater collection system is synthesized by a number of modules of a pool, the product has a long service life, construction is convenient, short construction period, lower cost.
Application of rainwater recycling system:
At present, rainwater recycling is mainly applied in the following aspects:
1. Rainwater collection, through the modular water storage tanks to collect rainwater resources used for flushing toilets, watering pavements, watering the lawn, water features, and even used for recycling cooling water and fire water. It can alleviate the current situation of urban water scarcity, and is an effective way to open up new sources of income and cut down on expenses.
2, rainwater infiltration, rainwater infiltration through the cistern, supplementing groundwater resources, improve the ecological environment, so that freshwater resources are supplemented.
3, rainwater retention, when the rainfall is greater than the city's drainage capacity rainwater collection module will be stored, reducing the pressure of urban drainage, thereby improving the reliability of the urban flooding system, reduce urban flooding.
