【摘要】：隨著珠三角經(jīng)濟飛速發(fā)展、工業(yè)化進程不斷的加快、以及人口快速的增長,水環(huán)境污染問題已經(jīng)成為我省面臨的重大問題之一。大量的生活、生產(chǎn)廢水以及垃圾不經(jīng)處理直接進入河道,造成水體嚴重污染,致使水體發(fā)黑發(fā)臭、富營養(yǎng)化,在造成生態(tài)破壞的同時,嚴重影響居民的生活及身心健康。因此,對河涌污染水體治理技術的研究迫在眉睫,也有重要意義。本研究采用以投加IBC微生物制劑為主,輔以截污(政府另安排)、格柵物理處理、人工復氧、放養(yǎng)水生動植物,構建恢復生態(tài)平衡系統(tǒng)的WOSC組合生物修復技術,其不僅有削底泥作用還可以降解污染物,使污染水體得到凈化。利用九村涌污染水體進行小試,考察了IBC微生物制劑對河涌污染水體治理效果,探討其強化機理,并在九村涌污染水體生態(tài)修復工程進行了驗證,具體內(nèi)容及結論如下:(1)IBC微生物制劑應用于九村涌污染水體進行小試,結果表明,投加IBC微生物制劑,可以有效去除水體有機污染物,效果顯著,COD、NH3-N、TP最高去除率分別為62%、78%及75%。同時微生物的活性也有很大的增長,顯著提高原土著微生物活性。(2)WOSC組合生態(tài)修復技術應用于佛山市南海大瀝鎮(zhèn)九村涌的工程驗證,在實際河涌修復項目中,取到比較好的治理效果。本文選取COD、NH3-N、BOD及TP作為污染水體主要指標。前期經(jīng)過6個月運行后,水體DO維持在3 mg·L-1左右COD、NH3-N、TP、BOD的平均降解率為47.1%、54.30%、38.1%和58.4%,河涌黑臭基本消除,水體得到凈化。后期經(jīng)過三個月運行,污染水體主要指標變化穩(wěn)定,基本維持在Ⅴ類地表水水質(zhì)標準以上。(3)WOSC組合生態(tài)修復技術在九村涌污染水體治理工程中驗證表明,其對河涌的黑臭有很好的治理效果,而且節(jié)省投資,影響因素小,在目前嚴峻的水污染環(huán)境下,該技術在河涌、湖泊等污染水體治理有很好的市場前景。
[Abstract]:With the rapid development of economy in the Pearl River Delta, the accelerating process of industrialization and the rapid growth of population, the problem of water environment pollution has become one of the major problems facing our province. A large number of life, production wastewater and garbage directly into the river without treatment, resulting in serious water pollution, resulting in water blackness and odor, eutrophication, while causing ecological damage, serious impact on the lives of residents and physical and mental health. Therefore, the study of water pollution treatment technology is urgent and significant. In this study, WOSC combined bioremediation technology was established by adding IBC microbial agents, supplemented by sewage interception (arranged by the government), grid physical treatment, artificial reoxygenation, stocking aquatic plants and animals, and restoring ecological balance system. It can not only degrade pollutants, but also purify polluted water. In this paper, the effect of IBC microorganism preparation on the treatment of polluted river water was investigated, and its strengthening mechanism was discussed. The results were verified in the ecological restoration project of Jiucun polluted water body. The specific contents and conclusions are as follows: (1) IBC microbiological preparation was applied to Jiucun polluted water for a small scale trial. The results showed that adding IBC microbial preparation could effectively remove organic pollutants in water, and the highest removal rates of COD NH 3-NN + TP were 622 78% and 75% respectively. At the same time, the activity of microorganism has also been greatly increased. (2) WOSC combined ecological restoration technology has been applied to the engineering verification of Jiucun, Dali Town, Foshan City, and has been applied in the actual river restoration project. Take a better governance effect. In this paper, NH3-Nbod and TP were selected as the main indexes of polluted water. After 6 months of operation, the average degradation rate of do in water was 47.1% and 58.4%, respectively, which was maintained at 3 mg L ~ (-1), and the water was purified. After three months of operation, the main indexes of polluted water changed steadily and remained above the water quality standard of Class 鈪，
