Embodiment Construction
[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0027] According to the general understanding, the water body in the artificial landscape lake is easy to turn black, smelly, and lose its landscape function after standing still for a long time. Therefore, the water body in the lake needs to be replaced regularly. This replacement period is called the water change period. During the water exchange period, the water body has strong fluidity, and the water body is replaced by hydrodynamic force. However, the water exchange conditions of general artificial landscape lakes are limited by the water source, and the water exchange cycle and each water exchange time are limited. Most of the time is in the non-water exchange period, that is, the still water period. During the static water period, the water fl...

The invention discloses a whole-water-area water flow circulation method of an artificial landscape lake. A closed-loop water flow flowing scheme is designed along a connected water area between the periphery of the lake and an island in the lake according to the area and the shape of the artificial landscape lake, namely a closed curve is used for indicating a water flow circulating flowing path, and arrows indicate the flowing direction. Water flow accelerating devices are arranged on the water flow circulating flowing path according to the closed-loop water flow flowing scheme and drives water flow to flow. A flowing speed influence range is determined according to flowing speeds of a water inlet pipe and a water outlet pipe, the quantity and the position of the water flow quickening devices are determined according to the length and the flowing speed influence range of the water flow circulating flowing path, and the water flow quickening devices are sequentially arranged in the lake along the water flow circulating flowing path. The whole-water-area water flow circulation method achieves whole-water-area water flow circulation in the lake area, enables water body flowability of lake water to be increased in manual hydraulic circulation mode when lake water is in standing water phase, promotes convection exchange and dilution of water body pollutants, is favorable for enhancing water body self-cleaning capability, quickens pollutant degrading, and improves water body water quality.
Description
technical field [0001] The invention belongs to the field of construction and environmental engineering, and in particular relates to a water flow circulation method in the whole water area of an artificial landscape lake. Background technique [0002] As a hydraulic engineering facility to improve the living environment, the artificial landscape lake is very important in today's shrinking water area. For example, artificial lake water system in urban construction planning, landscape lakes built in parks, lakes surrounding commercial and trade areas, lakes in high-end residential areas, etc. These artificial lakes provide suitable landscape atmosphere, improve the quality of urban environment, and provide more A rich entertainment and leisure environment can alleviate the urban heat island effect, improve local atmospheric conditions, meet people's water needs, and promote regional social and economic benefits. [0003] With the rapid development of China's economy, artif...
