【摘要】：蘇州城區(qū)從2011年起,通過斷頭浜打通、干河清淤、控源截污、自流活水、石湖水質(zhì)提升工程等一系列動作,通過三年的努力,城區(qū)水質(zhì)有了顯著改善,解決了水暢、水動、水活的問題。但是水體透明度、水體環(huán)境感官仍與市民百姓的期望有較大差距。為進(jìn)一步提升城區(qū)河道水質(zhì),恢復(fù)“小橋流水”的古城水巷風(fēng)貌,實(shí)現(xiàn)“水清、水美”的目標(biāo)。通過赴杭州、昆山等地考察,選取上海太和水環(huán)境科技發(fā)展有限公司的“食藻蟲引導(dǎo)水體生態(tài)系統(tǒng)構(gòu)建技術(shù)”在蘇州古城區(qū)東北街河進(jìn)行生態(tài)試驗,試驗周期從2014年12月至2015年7月。本文以東北街河水體生態(tài)修復(fù)試驗整個過程為研究對象,選取2014年12月至2016年7月的水質(zhì)監(jiān)測數(shù)據(jù),以水體透明度作為作為水清主要評價因子,綜合分析蘇州東北街河區(qū)域的自然地理和水體現(xiàn)狀,分析該河道存在的問題,并結(jié)合相關(guān)問題提出食藻蟲控藻修復(fù)方案,論述食藻蟲控藻修復(fù)方案的設(shè)計思路、理念、原則、依據(jù),并在前期工程、水體曝氣、沉水植物、食藻蟲、水生動物菌落、生態(tài)平衡幾個層面,細(xì)化目標(biāo),落實(shí)具體的執(zhí)行方案。通過對照組試驗的方式對其進(jìn)行數(shù)據(jù)分析,分析食藻蟲控藻修復(fù)對河道的透明度、水質(zhì)的改變。通過大量的實(shí)驗證明,在蘇州東北街河水體生態(tài)修復(fù)中應(yīng)用食藻蟲控藻修復(fù)可有效的提升透明度,但在氨氮、總磷、總氮中并沒有良好的改善作用。通過對實(shí)驗影響因素的分析,了解到要想該實(shí)驗獲得成功,需要滿足河床適合、光照適合、水流量不大、污染物不多的要求,唯有滿足以上四條,才能進(jìn)行食藻蟲控藻修復(fù)方案的復(fù)制和推廣,否則需要按照當(dāng)?shù)氐膶?shí)際情況,進(jìn)行客觀分析、重新設(shè)計方案。研究食藻蟲控藻修復(fù)方案在東北街河水體生態(tài)修復(fù)的有效性,為河道水生態(tài)修復(fù)積累經(jīng)驗,以期推動蘇州市食藻蟲控藻修復(fù)方案的實(shí)施。
[Abstract]:Since 2011, the urban area of Suzhou has made a series of movements through breaking the head and creek, clearing up the silt in the dry river, controlling the pollution of the source, flowing water and improving the quality of the water quality of the Stone Lake. Through three years' efforts, the water quality of the city has been greatly improved and the problems of water flow, water movement and water are solved. However, the water transparency and the sense of water environment are still larger than the expectations of the citizens. In order to further improve the water quality of the urban waterways, restore the ancient city waterway features of the "small bridge water", achieve the goal of "water clear, water beauty". Through the visit to Hangzhou, Kunshan and other places, the "algae feeding ecological system construction technology" of the Shanghai Taihe water environment science and Technology Development Co., Ltd. is selected in the Northeast Street River of the ancient city of Suzhou. The ecological experiment was carried out from December 2014 to July 2015. In this paper, the whole process of the ecological restoration test of the river body in Northeast street was studied. The water quality monitoring data from December 2014 to July 2016 were selected and the water transparency was used as the main evaluation factor for the water quality. The natural geography and water of the Northeast Street River area of Suzhou were comprehensively analyzed. To analyze the existing problems of the river, and to put forward the remediation scheme of alga controlled algae by combining related problems, and discuss the design ideas, ideas, principles and basis of the phyto control scheme for algae feeding and algae control, and to implement specific implementation in the previous project, water aeration, submerged plants, algae feeding, aquatic animal colonies and ecological balance. Through a large number of experiments, it is proved that algae control can effectively improve the transparency of algae control in the river body ecological restoration of Suzhou northeastern street, but there is no good in ammonia nitrogen, total phosphorus and total nitrogen. Through the analysis of the influence factors of the experiment, we know that the success of the experiment is to meet the requirements of the suitable river bed, the light fit, the low flow of water, and the few pollutants. Only by satisfying the above four, can the algae control algae control scheme be replicated and popularized, otherwise it should be carried out according to the actual situation of the local area. In order to promote the implementation of the algae controlled algae control scheme in Suzhou, the effectiveness of the algae - controlled algae - controlled restoration scheme on the ecological restoration of river water in northeastern street was studied.
