摘要:
喷泉水景被广泛应用于景观水体,其扰动强度大、压力大、水交换量大、曝气量高等特点,在改善水体水质方面具有广阔的应用前景.因此,通过室内模拟实验,研究了喷泉水景的复氧与控藻能力,结果表明:喷泉压力为25 ~45 kPa时,作用15 min后,喷泉能将能将水体中溶解氧含量接近饱和溶解氧90 %,喷泉复氧的KLa(20)和OC平均值分别为0.327 1/ min和0.028 1 kgO2 /min;喷泉水景能对水体微囊藻的生长起到很好的抑制作用,压力越大,抑制作用越强,在40 kPa、45 kPa压力下,最大控制率达到了80 %以上,且能持续抑制藻类生长;喷泉水景的控藻能力主要是基于喷泉的强大扰动作用及喷泉管内压力破藻作用.实际喷泉水景不但具有很好的景观效果,而且在景观水体的复氧修复、抑制水华及破坏水体分层、改善底泥环境等方面具有重要作用
Abstract:
Fountain waterscape was widely applied to urban landscape water body. Based on the characteristics, such as high ability in aeratingand and perturbing, large internal pressure in pipeline and water exchange capacity between on the upper and lowwater layers, fountain waterscape has a wide application prospects for water purification in landscape water body environment. Therefore, laboratory experiments were carried out to study the reoxygenation and algal inhibition ability of fountain waterscape in this study. Results showed that the dissolved oxygen content in water was close to 90% of its saturation value in about 15 min during the fountain reoxygenation with water-pump pressure ranged for 25 KPa~45 KPa. The KLa(20) and OC ′s average of fountain reoxygenation were 0.327 1 min-1 and 0.0281 kgO2 min-1. Fountain waterscape for the growth of Microcystis aeruginosa had a certain effect, and the algal inhibition ability was proportional to the pressure in fountain pipeline. The algal inhibition effect of fountain was mainly based on fountain high ability in perturbing and alga cells were broken by the internal pressure in pipeline. An actual fountain waterscape not only had very good landscape effect, also played important roles in landscape water body reoxygenation and restoration, inhibiting blooms, destroying water temperature stratification and improving mud environment,and so on.
