摘要：道路雨水徑流含有大量污染物質(zhì)，且初期雨水徑流帶來的污染物負荷最為嚴重。初期雨水徑流污染不能僅靠分流制排水系統(tǒng)，由于分流制排水系統(tǒng)也存在一些缺陷，而且目前國內(nèi)很多城市舊城區(qū)合流制的分流改造效果也不盡理想。因此，應(yīng)改變傳統(tǒng)的規(guī)劃設(shè)計理念和施工技術(shù)，進一步改進與創(chuàng)新，通過新技術(shù)、新方法和新理念，達到解決城市排水系統(tǒng)和初期雨水徑流污染問題。目前各種初期雨水控制設(shè)施都有其限制因素，本文提出一項“路沿式排水槽”新技術(shù), 替代傳統(tǒng)雨水管道，道路雨水通過“路沿式排水槽”的導流溝和過濾層凈化過濾,有效控制道路初期雨水徑流污染問題，降低雨水徑流污染負荷，同時解決舊城區(qū)合流制的分流改造問題，達到控源截污，源頭治理之目的。

Abstract： Road stormwater runoff contains a large number of pollutants, and the initial rainfall runoff is the most serious pollutant load. The initial rainwater runoff pollution cannot only depend on the drainage system, the drainage system has some defects, and many domestic old city reconstruction effect of confluence shunt is not ideal. Therefore, we should change the traditional planning design and construction technology, further improvement and innovation, through new technology, new methods and new ideas to solve the problem of city rainwater runoff pollution and early drainage system. The initial rainwater control facilities has its limitations, this paper proposes a new technology of road along the drainage groove, to replace the traditional rainwater pipes, rainwater through the edge of the road drainage trough "diversion ditch and filter layer filtration, road rainwater runoff pollution control, reduce rainwater runoff pollution at the same time load, solve the old city reconstruction system shunt confluence, achieve pollutant source control, the purpose of source control.
