Anti-blocking bioretention pond system and working method thereof
The invention discloses an anti-blocking biological detention pond system and a working method thereof. The system comprises a pulse plant filter bed which runs in a pulse mode, and a floating ball valve is installed at an outlet of the pulse plant filter bed; the breathable bioretention pond sequentially comprises a water storage layer, a substrate layer, permeable geotextile and a broken stone hardcore from top to bottom, a permeable breather pipe with holes in the side wall is vertically mounted in a pond body, an overflow well is arranged in the center of the pond body, a perforated drain pipe is arranged on the broken stone hardcore, and the breathable bioretention pond is connected into a rainwater pipe canal through a height-adjustable telescopic drain pipe. By means of plant filter bed pretreatment, breather pipe installation, pulse water inlet and the like, matrix blockage of the bioretention pond can be effectively prevented, the initial rainwater retention and purification effect is enhanced, and meanwhile the service life is prolonged.
本发明公开了一种防堵塞型生物滞留池系统及其工作方法，系统包括脉冲植物滤床：脉冲式运行，出口处安装有浮球阀；透气型生物滞留池：从上至下依次为蓄水层、基质层、透水土工布和碎石垫层，池体中垂直安装侧壁开孔的渗透型通气管，池体正中设置溢流井，碎石垫层布设穿孔排水管，通过可调节高度的伸缩式排水管接入雨水管渠。本发明可通过植物滤床预处理、安装通气管以及采用脉冲进水等方式有效防止生物滞留池的基质堵塞，在增强初期雨水滞蓄与净化效果的同时延长使用寿命。
