【摘要】：基質(zhì)堵塞是潛流人工濕地在工程應(yīng)用中面臨的最嚴(yán)重的運(yùn)行管理問題之一。圍繞復(fù)合垂直流人工濕地(IVCW)基質(zhì)堵塞問題,在系統(tǒng)分析導(dǎo)致基質(zhì)堵塞的結(jié)構(gòu)和工藝缺陷的基礎(chǔ)上,研究了增加基質(zhì)層深度以及增設(shè)配水管集水管和控制器的優(yōu)化措施對緩解基質(zhì)堵塞的效果。結(jié)果表明,結(jié)構(gòu)和工藝的優(yōu)化,克服了堵塞物質(zhì)容易在下行池表層基質(zhì)中較快累積的弊端,同時加快了堵塞物質(zhì)的礦化分解。由初步的模型預(yù)測可見,結(jié)構(gòu)和工藝的優(yōu)化措施,使改進(jìn)后的系統(tǒng)有效使用壽命延長至原有系統(tǒng)的2.77倍。
[Abstract]:Matrix plugging is one of the most serious problems in the operation and management of subsurface constructed wetland. Based on the analysis of the matrix blockage of the composite vertical flow constructed wetland (IVCW), based on the systematic analysis of the structural and process defects resulting in matrix blockage, the effect of increasing the depth of the matrix layer and adding the optimization measures of the water distribution pipe and the controller to mitigate the plugging effect is studied. The results show that the optimization of structure and technology overcomes the disadvantages of clogging substances easily accumulating in the surface matrix of downstream ponds, and accelerates the mineralization and decomposition of plugging materials. It can be seen from the preliminary model that the optimization measures of structure and process make the effective service life of the improved system extend to 2.77 times that of the original system.

【正文快照】： 復(fù)合垂直流人工濕地(IVCW)能高效去除水中氮、磷、有機(jī)物等常規(guī)污染物,在國內(nèi)外的污水處理項目中得到廣泛應(yīng)用[1,2]。與其他類型的潛流人工濕地類似,IVCW在長期運(yùn)行過程中同樣面臨基質(zhì)堵塞問題[3]。隨著堵塞的發(fā)生,基質(zhì)的水力傳導(dǎo)性能逐漸降低,初期造成污水無法在設(shè)定的時間內(nèi)，
