Abstract
本发明公开了一种码头雨水的集蓄净化与回用***,涉及码头初期雨水收集回用技术领域。该***由旋流沉砂式雨水井、雨水花园和回用单元组成;所述旋流沉砂式雨水井由雨水井井体、进水管、海绵混凝土输水渠和溢流管组成;所述海绵混凝土输水渠采用海绵混凝土砌筑;所述雨水花园从上至下依次由种植层、介质层和排水层组成;所述介质层的内部均匀分布复合菌群多层固定化小球;所述回用单元由地下集水池和回用泵组成。由地下集水池集蓄经雨水花园净化处理过的雨水,通过回用泵将其输送至堆场用水点、路面用水点、绿化带用水点和生活区用水点等码头用水点。本发明能够有效收集散货码头面的雨水,增加了雨水的下渗速率,减小了雨水径流量,提升了雨水水质,可直接作为码头面冲洗用水,减少了雨水径流污染,并且节约水资源,具有结构简单紧凑、运行成本低、易于控制、雨水回用率高、环境友好等优点。
Description
技术领域
本发明属于对码头初期雨水收集回用技术领域,特别是提供一种码头雨水的集蓄净化与回用***。
背景技术
目前,在港口码头中,大多雨水是直接排放,造成浪费,一般的港口码头的建筑结构中,大多没有实现码头雨水的集蓄净化与回用,而是一般采用在码头横向设置排水沟的方式,即平行于码头横梁的方向设置排水沟,由码头两侧向中间排水沟排水。但采用该方法导致码头面初期雨水的收集利用率很低,大部分雨水无法有效流入排水沟中,使得初期雨水直接流入自然水体中,造成对自然水体的污染与雨水资源的浪费。
与此同时,当前缺乏高效的码头雨水收集、净化和回用***。因此如何实现码头雨水的高效收集、净化和回用是现在需要解决的关键问题。本发明结合了“海绵城市”的设计理念,秉承着绿色、生态、环保的原则,针对码头初期雨水的水质特点,设计开发了一种码头雨水的集蓄净化与回用***。
发明内容
为了解决码头雨水的收集、净化和回用中存在的技术难题,缺乏高效的码头雨水收集、净化和回用***,本发明提供了一种结构简单紧凑、运行成本低、绿色环保、易于控制且雨水回用率高的码头雨水的集蓄净化与回用***。

(3)雨水花园介质层内填料中的小陶粒与秸秆为改性剂,小陶粒易挂膜,能吸附水中的污染物质,秸秆透水性和持水性好、天然环保、节水节肥,该填料结构有利于去除水中的污染物质并保持土壤水分。
(4)雨水花园介质层内填充有复合菌群多层固定化小球,使得厌氧氨氧化颗粒污泥和好氧硝化颗粒污泥的生物效能协调发挥,实现好氧硝化反应和厌氧氨氧化反应的协调运行;制备所述复合菌群多层固定化小球的方法简便,制作过程易于控制,得到的复合菌群多层固定化材料含水率高、机械强度高、可重复利用;同时利用固定化微生物技术生物浓度高、环境适应性强的特点,具有低成本、高效率、生态化等优点。
(5)雨水花园可降低雨水中80%悬浮物和其他污染物,出水水质能达到很高的水质标准,保障了回用水的水质。

具体实施方式
以下实施例仅处于说明性目的,而不是想要限制本发明的范围。
实施例1
如附图所示,本发明的一种码头雨水的集蓄净化与回用***包括旋流沉砂式雨水井(1)、雨水花园(2)和回用单元(3);旋流沉砂式雨水井(1)包括雨水井井体(1-1)、进水管(1-2)、海绵混凝土输水渠(1-3)和溢流管(1-4);所述雨水花园(2)从上至下依次设置有种植层(2-1)、介质层(2-2)和排水层(2-3);所述介质层(2-2)内部分布有复合菌群多层固定化小球(2-5);所述回用单元(3)包括地下集水池(3-1)和回用泵(3-3);旋流沉砂式雨水井(1)设置于透水路面下方,雨水花园(2)设置在绿化区内侧,回用单元(3)设置于堆场后方;所述旋流沉砂式雨水井(1)通过海绵混凝土输水渠(1-3)和溢流管(1-4)将雨水输送至雨水花园(2),所述雨水花园(2)通过连接管道(2-8)连接回用单元(3);收集的雨水经过旋流沉砂雨水井(1)和雨水花园(2)的处理之后可以循环利用;所述回用单元(3)通过回用泵(3-3)将地下集水池(3-1)中的经雨水花园(2)净化处理过的雨水回用到堆场用水点(3-4)、路面用水点(3-5)、绿化带用水点(3-6)和生活区用水点(3-6)。

所述种植层(2-1)上种植有耐旱抗涝植物(2-6),所述耐旱抗涝植物(2-6)为鸢尾和芦苇的组合。
