What is a rainwater harvesting system used for? How to do rainwater harvesting system information

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.

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.

What kind of equipment does the rainwater harvesting system install?

The first category: buried process.

Summary. Rainwater mobile devices are generally made of buckets 1, round (the water flow of the round barrel is even, and the dead corner area where the water does not flow is easy to produce bacteria).

2. What does a closed and opaque rainwater collector look like (a light-transmitting bucket, the bacteria in the water carry out photosynthesis and produce baths).

Rainwater mobile devices are generally made of buckets 1, round (the water flow of the round barrel is uniform, and the dead corner area where the water does not flow is easy to produce bacteria) 2. Closed and opaque (hail only transparent barrels, and the bacteria that disturb the mold in the water carry out photosynthetic slowing and slowing to produce baths).

That's what it usually looks like.

With the increase of population, the reduction and development of cities, and the rapid increase of urban and rural water consumption, it is a very valuable research topic to collect and use rainwater in the case of lack of existing water resources, so that rainwater resources can serve the society.

As we all know, there are only two water storage in an area: one is to rely on surface precipitation, which includes rainfall, snow, fog, hail, etc.; The second is to rely on groundwater. Groundwater reserves are determined by the structure of the local site, which is formed by the accumulation of catchments over many years.

With the exploitation of groundwater, groundwater reserves are decreasing year by year, so it is supplemented, the amount of water in an area largely depends on the precipitation in the area and the amount of precipitation that is intercepted, the precipitation intercepted is more, the water consumption is relatively sufficient, and the precipitation intercepted is less or no measures are taken to intercept the precipitation, then the natural precipitation will be lost in vain.

Northeast China is located in the north temperate continental climate zone, and most of the annual precipitation is summer rainfall, and most areas have high summer temperatures and concentrated rainfall. In particular, in recent years, due to the changes in the global climate and the influence of creating wind-blown sand shelter forests and tree planting, the total amount of rainfall in summer is more than that of previous years, and the rainfall is large, which should reflect the usefulness of collecting and utilizing rainwater resources.

Rainwater harvesting methods are made up of many, different regions, and different methods can be employed.

In urban areas, simple small seepage wells can be built on vacant land in a planned way (see Figure 1). Set up rainwater pipelines to collect rainwater in a plurality of seepage wells, and rely on the seepage layer in the wells to slowly infiltrate the stored water into the ground, so that the rainwater can be converted into groundwater, which can replenish groundwater.

Another option is to construct rainwater harvesting outlets. Stormwater outlets with seepage layers are built on both sides of blocks, houses, and roads, and these stormwater outlets collect, transfer, and discharge rainwater runoff from catchment areas such as blocks, residential areas, and roads, and seep part of the rainwater into the ground. It can not only reduce the amount of water transferred to the downstream drainage pipe section, reduce the pressure on the municipal combined drainage pipe, but also collect rainwater to replenish groundwater.

These two methods of collecting rainwater can be used in some areas, especially factories, mines, enterprises, gardens, etc., so that they can play a good social benefit.

In rural areas, if there is a lot of precipitation and timely replenishment, reservoirs can be used to raise fish, or aquatic plants can be planted to provide food for livestock. In the dry season, the water pump absorbs the rainwater in the reservoir, which can be used to irrigate the farmland, so as to solve the problem of short-term water shortage in the dry season, so that the reservoir can play the role of a "small reservoir", which is worth using in the countryside, and in the dry season, farmers can use these empty pools for district fertilizer, so that a pool can be used for multiple purposes.

A very effective way to intercept rainwater is to plant trees, and call on people everywhere to carry out extensive afforestation activities in the local area to green barren mountains and beautify cities. Through tree planting, the rainfall in the region can increase, the air is humid, which is good for crops and people's lives, and long-term tree planting can form a good green interception of rainwater, and the prairie can serve the present and benefit the future.
