With the rapid development of the city, urbanization has further accelerated, and environmental beautification has developed into a large and complete industrial chain. Various landscapes such as fountain waterscapes attract people's attention, and the water landscape plays an important role in improving the quality of the living environment and enhancing the image of the city. There is water, and the value of the house is also enhanced by water. This is because the water landscape increases the comfort of the living environment, improves the microclimate of the living area, and makes people feel the return to nature. The organic combination of fountain water landscape and urban square and residential community construction has become an important part of the city's highlights and spiritual civilization construction, and is deeply loved by the general public.
At present, many water fountains in China have different degrees of water quality deterioration. Especially when organic matter, phosphorus, nitrogen and other substances are accumulated in water, they will promote the rapid propagation of algae, while the algae will consume oxygen in the water during the growth and growth process. To make the water eutrophic. The reason for the eutrophication is that there is no water treatment facility in the landscape water body, and a considerable part of the fountain waterscape project does not have the installation of water treatment equipment in order to save investment, so the water quality of the third and fourth types of landscape water specified in the regulations cannot be met. standard. Although these projects have beautified the environment as a whole, they have also polluted the environment on the other hand.
The use of urban rainwater and medium water resources has received increasing attention and attention from all over the world. Especially in developed countries, the collection and utilization of urban rainwater has reached a high level, such as France, Germany, Japan, Australia, Belgium and other countries, roofing and ground. Rainwater harvesting and utilization has been widely used as a source of important production and domestic water. For example, the main venue of the Sydney 2000 Olympic Games in Australia, in order to use the water and rain, built a number of reservoirs, also invested 8 million Australian dollars to build a water treatment plant, daily processing capacity of about 15,000 cubic meters, after physical chemistry UV disinfection, membrane treatment, clear and transparent water, no odor.
Water conservation is a basic national policy of our country. The fountain waterscape project is recycled water. During the operation, atomization, drift and leakage will also cause a considerable part of water loss. However, China's water resources are increasingly lacking. The water source of the fountain waterscape will be rainwater, middle water, and rainwater. The rational development and utilization of Zhongshui will bring more market opportunities.
