What is the design concept of the rainwater harvesting system?

Different designers have different understandings of each different thing, which is reflected in the work, and there will be a lot of differences, according to the experience of Sponge Rain Company, no matter how the design is made, the following rules should be followed.

1. Technological advancement.

Rainwater treatment and reuse projects should reflect the concept of environmental protection, and the processes and technologies used will not be obsolete in the future, so as to avoid repeated transformation. Therefore, equipment and technology should be considered first in the selection of rainwater treatment process.

2. Safety rules.

Since rainwater reuse is related to the safety of the surrounding people, there can be no problems with the quality of rainwater treated water. The recommended treatment technology and treatment system for rainwater reuse projects should have high-quality effluent and safety measures.

3. System modularity.

In order to reduce operating costs, the treatment equipment using modules should be considered when selecting treatment equipment, and the system operation combination can be combined according to the amount of rainwater generated to reduce operating costs.

4. Occupy less land.

The selection of rainwater treatment technology should also consider the use of equipment and technology with small footprint and high operating efficiency.

When the rainy season came, flooding became a common phenomenon. In this era of promoting energy conservation and environmental protection, how to convert rainwater into resources. The utilization of rainwater in urban residential areas is a new type of multi-objective comprehensive technology, which not only has the significance of using rainwater resources and saving water, but also includes the reduction of rainwater flooding and groundwater decline in urban areas, the control of rainwater runoff pollution in the area, and the protection and improvement of urban ecological environment.

Zhongke Yujie will introduce you to the current rainwater application technology:

1) Rainwater harvesting and utilization system for decentralized dwellings;

2) Centralized rainwater harvesting and utilization system in dense areas of buildings or residential areas;

3) Decentralized ground rainwater infiltration system;

4) Centralized ground rainwater infiltration system;

5) roof garden rainwater utilization system;

6) Comprehensive utilization system of rainwater in ecological communities.

Specific rainwater utilization methods include:

1) The accumulation and utilization of rainwater is an effective way to alleviate the current shortage of urban water resources, and it is a new effective way to open up sources and reduce expenditure.

2) The indirect utilization of rainwater is to infiltrate rainwater back into the ground, which can effectively supplement and conserve groundwater resources, improve the ecological environment, alleviate soil erosion and seawater intrusion, and reduce waterlogging.

3) Comprehensive utilization of rainwater, making full use of the city's existing rivers and lakes, artificial and natural water bodies, swamps, wetlands for storage, purifying and utilizing urban runoff rainwater to reduce waterlogging and improve the water environment system.

A variety of different rainwater harvesting processes are targeted to effectively treat rainwater from different catchment surfaces. It can not only effectively collect rainwater but also control the cost and take into account the systematic rainwater pretreatment, rainwater storage, rainwater deep purification, rainwater supply, water replenishment and system control, which is comprehensive and scientific. The use of a large number of new corresponding devices, materials, can effectively solve the special problems encountered in rainwater collection, such as abandonment, water storage, water supply, etc.

In the collection design, the characteristics of rainwater artesian flow are used as much as possible to complete the automatic discharge, purification and collection of pollutants, so as to achieve the characteristics of real energy saving, environmental protection, high service life and low cost. In addition, the whole system is controlled by the rainwater controller to complete the functions of collection, purification, water supply, water replenishment, and safety protection.

To put it simply, it is through certain equipment, facilities, and technology to collect natural rainfall, and treat it for irrigation, greening, construction, urban road water, etc., which can protect the natural ecological environment, recycle water resources, solve the problem of water shortage, and at the same time reduce flood pressure and bring people a better and happier life, so do you know what problems must be considered in advance when building and applying rainwater collection systems?

First, pay attention to the safety of rainwater harvesting.

Second, rainwater harvesting should follow the laws of nature.

Third, rainwater collection should be filtered.

Fourth, plan the use and amount of rainwater harvesting.

Rain is a gift from nature to human beings, but once there is continuous heavy rain and torrential rain.

In order to cope with the problem of flooding, it is necessary to establish a rainwater harvesting system, which can not only enhance the city's resilience to flood disasters, but also effectively use rainwater for car washing, toilet flushing, and greening.

Rainwater Harvesting System Benefits:

The benefits of rainwater harvesting system are to replenish urban groundwater, alleviate land subsidence, regulate climate, purify air, enhance urban greening, prevent and control rainwater disasters, reduce the load of urban drainage and treatment systems, reduce flood control pressure, reduce rainwater runoff pollution, and use urban rivers and lakes and various artificial and natural water bodies, swamps, and wetlands to regulate climate and curb urban heat island effect.

improve the urban ecological environment;

The use of the rainwater harvesting system pool in the rainwater harvesting system pool.

Rainwater harvesting system pools are mainly used to store rainwater after initial treatment. It is best to use PP material for rainwater harvesting system pools.

Compared with traditional cement pools, it has the following advantages: long service life and product design.

Flexible, convenient transportation, simple construction and low cost;

Sponge city. The use of rainwater collected in .

There are rainwater collection systems everywhere in the sponge city, and the rainwater on the road surface flows into the storage tank through the catchment pipe, and then it is used for fire fighting, greening, and road washing; The plaza collects and purifies rainwater through waterways for landscaping, greening, and public health.

Space; After the building collects rainwater from the roof and ground, it can be used for fire fighting, toilet flushing, greening and wall pavement washing.

1. An important measure to solve the problem of urban water shortage and flood control. Rainwater utilization is the collection, concentration and storage of rainwater flowing from nature or man, and it is a method of obtaining water from the hydrological cycle for human use. The use of rainwater will make an important contribution to solving the problem of water scarcity in the future.

2. It can improve the ecological environment, replenish and conserve groundwater, reduce flood and drought disasters, effectively alleviate the difficulty of drinking water in rural areas, promote the development of agriculture and increase farmers' production and income, and improve the living conditions of human settlements. Promote the construction of new rural areas.

3. It can save water and reduce water costs. Rainwater collection from municipal roads can eliminate pollution and reduce social losses, save the operating costs of urban drainage facilities, and save water to increase the financial income of the surrounding family. Rainwater harvesting from municipal roads can also bring benefits by improving the city's ecological environment.

Rainwater effectively improves the regional ecological environment. Rainwater harvesting, utilization, or recharging underground can reduce the pressure of flood control and drainage in the city, and prevent the city from being damaged by drainage facilities.

The rainwater harvesting system can infiltrate more rainwater into the city's underground and store it, alleviating urban waterlogging, delaying peak onset times, and reducing peak flows. Create conditions for the utilization of rainwater resources, take a variety of measures to store water, purify water, reduce pollution, improve the urban water environment, improve the efficiency of water resource utilization, and discharge excess rainwater out of the city through the underground pipe network.

The use of urban rainwater should be based on the different ecological environment, water characteristics, building distribution characteristics and other factors in various regions, so as to maximize the utilization of urban rainwater. There are several main ways of urban rainwater**:

Dr. Rain |Rainwater harvesting systems.

1. Establish urban rainwater storage facilities.

Rainwater storage facilities are divided into two forms of ground water storage and underground water storage, urban surface, roof, parking lot and other large buildings can be regarded as a water collection surface, through an effective transmission system to transport rainwater to reservoirs, reservoirs and other water storage facilities, some developed countries mostly choose iron roof collection, the collection of runoff stored in the reservoir. The most economical way is to optimize the low-lying areas of the city and equip them with appropriate water diversion facilities to store rainwater runoff. In addition, it can also make full use of the rainwater drainage pipe network system that has been established in the city, integrate the urban terrain direction, and establish comprehensive and systematic water storage engineering facilities.

However, when there is a shortage of land on the ground, it is necessary to consider the use of underground reservoirs, which are of many types and shapes, and can be designed according to the needs of rainwater infiltration.

2. Establish a rainwater collection and utilization system in the park.

In new living quarters, parks or similar urban parks with better environmental conditions, rainwater runoff from roofs, green spaces and roads can be collected and utilized, so as to significantly reduce urban rainstorm runoff and non-point source pollutant discharge, optimize the community water system, reduce waterlogging and improve the environment. Because this kind of system is larger and more extensive, it is necessary to deal with the initial rainwater interception, purification, green space and road elevation, indoor and outdoor rainwater collection and drainage systems, and the surface runoff generated by various related rainfall. As long as some simple rainwater storage projects are built, urban rainwater can be recycled, so that it can be used for urban cleaning, green space irrigation, and maintenance of urban water landscape.

Because rainwater pollution is not very serious, it can be used for domestic washing water, industrial water, etc. through simple treatment.

The rainwater and utilization engineering of modern cities involves a wide range of fields and is also relatively complex, but it is also a very promising development field. Therefore, when doing rainwater and utilization, we should adhere to the principle of adapting measures to local conditions and seeking truth from facts to choose the utilization system, not just copy the rigid set, and fully consider the advantages and disadvantages of collection and utilization and various infiltration facilities as well as applicable conditions, and confirm the plan through water balance, hydraulic calculation and technical and economic analysis, so as to maximize the use of rainwater.

It is my pleasure to serve you, and your satisfaction is the goal of our efforts.

We will work harder to serve and better products of Ant Skin, and do better projects for you.

Dr. Rain |Rainwater utilization system.

In order to achieve the water quality regulations for the utilization of rainwater slag, when the rainwater flows through the absorption pipe network, the part of the rainwater filtration system that pollutes the environment will be discarded such as a mausoleum, so that the rainwater contains more soil waste will also be eliminated.

According to the catchment area, the classification is as follows:

1) The roof building catches water at the top.

2) Ground, road, greening.

3) Public places and sports grounds.

Significance of rainwater harvesting:

Rainwater harvesting connects people and the environment and promotes mutual development. At rainwater harvesting sites, it actually provides human life by generating new sources of water. Upstream, it can reduce the need to exploit external water resources; Downstream, it can reduce excess urban runoff and associated pollution, erosion, and flooding, thereby maintaining water quantity and quality.

System Composition:1Catchment area: The surface of the rainwater landing site.

2.Water conveyance system: A channel or pipe that transports rainwater from the catchment bricks to the water storage system.

3.Roof flushing system: This system filters and removes contaminants and debris.

4.Water storage system: used to store collected rainwater.

5.Water distribution system: Uses gravity or pumps to distribute rainwater.

6.Purification system: includes filtration equipment, purification equipment and additives for sedimentation, filtration and disinfection.

I know that there are domestic Shangu environmental protection, foreign German sub-department and so on.

The rainwater collection system is a system that collects rainwater according to demand and treats the collected rainwater to meet the design standards. Nowadays, most of them are composed of waste flow filtration systems, water storage systems, and purification systems.

Rainwater harvesting systems can be roughly divided into two categories depending on the source of rainwater.

1. Roof rainwater. Rooftop rainwater is relatively clean, with little impurities, sediment and other pollutants, and can be discharged directly into the water storage system after being discarded and simply filtered, and then treated and used.

2. Ground rainwater. There are many impurities in the rainwater on the ground, and the sources of pollutants are complex. After abandonment and rough filtration, sedimentation must also be carried out before it can be discharged into the water storage system.
