摘要:- 肇慶市九坑河水源地總面積為46.42 km2，作為城市的飲用水源保護(hù)區(qū)、備用水源地，其水質(zhì)保護(hù)目標(biāo)為地表水Ⅱ類。近年隨著人類經(jīng)濟(jì)活動(dòng)的快速發(fā)展，水質(zhì)常年出現(xiàn)超標(biāo)情況。為解決水污染問題，針對(duì)項(xiàng)目工程范圍廣、水域面積大、水量時(shí)空變化量劇烈、污染源數(shù)量多但分散的特點(diǎn)，對(duì)主要超標(biāo)對(duì)象氨氮和總氮進(jìn)行處理。設(shè)立了從散居污染點(diǎn)設(shè)置單獨(dú)的處理設(shè)施，到集中污染點(diǎn)設(shè)置的污水處理站，再到入庫前設(shè)立的前置庫處理系統(tǒng)，最后到庫區(qū)內(nèi)設(shè)置的深度活水系統(tǒng)的4層處理體系，再輔以垃圾處理、清淤等配套措施，全方位對(duì)工程范圍內(nèi)的污染源進(jìn)行攔截和處理，最終達(dá)到了恢復(fù)Ⅱ類水體的目標(biāo)，為國內(nèi)同類型綜合整治工程提供了示范與參考。
Abstract:- The total area of Jiukenghe drinking water source in Zhaoqing City is 46.42 km2. As drinking water source protection area and reserve water source in the city, the water quality is required to meet class Ⅱ surface water standard. In recent years, with the rapid development of human economic activities, water quality frequently exceeds the required standard. In order to solve the water pollution problems, ammonia nitrogen and total nitrogen, as two main objects exceeding standard, have been removed according to the characteristics of wide project scope, large water area, dramatic change of water volume in time and space as well as large quantity and scattered pollution sources. The separated treatment facilities were built in scattered pollution sources points and the centralized wastewater treatment station was built in concentrated pollution source. Moreover, the pre-storage treatment system had been built before entering the reservoir and finally the deep active water system was set up in the reservoir area. In this way, the four-layer treatment system was established. In addition, the supporting measures such as garbage treatment and desilting were adopted to intercept and treat the pollution sources within the scope of the project in all directions, and finally the goal of restoring class Ⅱ water bodies was achieved, which provided demonstration and reference for the same kind of comprehensive improvement in China.
