Embodiment
[0071] figure 2 Among them, the aeration and oxygenation system 1 mainly includes two parts: falling water aeration, solar bionic plant aeration and aeration pump aeration. There are 8 rows of aeration in different areas of the landscape water body, 20 special nozzles for aeration and two submersible pumps are used. The calculation is as follows.
[0072] Landscape lake area: 240х130=31200m 2 , water depth: 2.5m;
[0073] The total water storage capacity of the landscape lake: 31200х2.5=78000m 3 ;
[0074] If calculated according to the processing cycle of 20 days, the daily processing capacity can be 4000m 3 calculate;
[0075] Handling per hour: 167m 3 ;
[0076] The actual water quality of the landscape lake: COD concentration: 100-120mg / L, calculated on the basis of 120mg / L, to meet the V-class surface water quality standard, the oxygen consumption of the pollutants in the landscape lake is 80mg / L, so that the oxygen consumption per ton of water : 0.08х1000=80g / m ...

The invention discloses a landscape water-body water-quality maintaining and self-purifying system integrating functions of landscape and biological ecological restoration. The system comprises an artificially intensified water quality purifying system, a biological control system and a water circulation system, and is used for ecological maintenance and self-purification of the campus landscape water body. By the artificially intensified water quality purifying system, mechanisms of water circulation and purification are utilized, so that the aim of purifying the landscape water-body water-quality is fulfilled; the artificially intensified water quality purifying system comprises an aeration oxygenation system, an ecological floating bed and a multi-element combined artificial wetland; the biological control system consists of an ecological island and an aquatic animal and plant system and is used for assisting the artificially intensified water quality purifying system to further improve the self-purification capability of a landscape water-body ecological environment; and each system is circularly connected with a processing unit by a water pump and gravity flow. By the landscape water-body water-quality maintaining and self-purifying system, the impact resistance and the water-body water-quality purifying capability of the campus landscape water-body ecological environment can be improved, and the problems of the pollution to the campus landscape water-body and landscape degradation are solved. The landscape water-body water-quality maintaining and self-purifying system is low in cost, low in investment, low in energy consumption, good in purifying effect, and free from secondary pollution.
Description
technical field [0001] The invention relates to the technical field of water pollution control and environmental restoration, in particular to landscape water quality ecological maintenance and self-purification technology. Background technique [0002] In recent years, campuses in many cities in my country have built landscape water bodies, which have played an important role in improving the ecological environment of campuses. In the process of landscape water operation, based on the theory of ecological conservation, people have also begun to adopt various measures to maintain and purify water quality. However, due to the immaturity of the theory and the lack of an effective combination of various ecological maintenance and water purification technologies, in the operation process of the landscape water body, there is a lack of an effective integrated system for campus landscape water ecological maintenance and water purification, which has been successfully used in actua...
