Rainwater recovery treatment process suitable for landscape architecture
The invention relates to a rainwater recovery treatment process suitable for landscape architecture, and belongs to the field of rainwater treatment. The process comprises the following steps: a, collecting rainwater for preliminary filtration; b, enabling the rainwater to flow into a primary sedimentation tank for primary sedimentation after being preliminarily filtered; c, overflowing rainwater supernate of the primary sedimentation tank to a secondary sedimentation tank, flowing through a rainwater treatment device filled with a flocculating agent, and performing flocculating sedimentation in the secondary sedimentation tank; d, pumping supernate of the secondary sedimentation tank for recycling; and e, regularly taking out and replacing the flocculating agent in the rainwater treatment device; wherein the side wall of the primary sedimentation tank is provided with a water flowing channel allowing rainwater to overflow, one end, away from the primary sedimentation tank, of the water flowing channel is communicated with a vertical shaft extending to the ground, the bottom end of the vertical shaft is communicated with the secondary sedimentation tank, and the rainwater treatment device is arranged at the vertical shaft. According to the treatment process, the rainwater can be better subjected to flocculent precipitation to be recycled, a worker only needs to replace a flocculation agent regularly, and good practicability and economic benefits are achieved.
本申请涉及一种适用于园林景观的雨水回收处理工艺，属于雨水处理领域。其包括以下步骤：a．雨水汇集收集进行初步过滤；b．雨水初步过滤后流入初沉池中进行初步沉淀；c．初沉池的雨水上清液向二沉池溢流，流经装有絮凝药剂的雨水处理装置，在二沉池中进行絮凝沉淀；d．泵取二沉池上清液即可回收利用；e．定期对雨水处理装置中的絮凝药剂取出更换；初沉池侧壁设置有供雨水溢流的流水通道，流水通道远离初沉池的一端连通有延伸至地面的竖井，竖井底端连通至二沉池，雨水处理装置设置在竖井处。本申请的处理工艺能够更好地对雨水进行絮凝沉淀以回收利用，工人只需定期更换絮凝药剂，具有良好的实用性以及经济效益。
