【摘要】：自古以來,城市內(nèi)河就是城市文化傳承、商業(yè)發(fā)展和休閑游憩的核心,是構(gòu)成城市的重要元素,也是促進(jìn)城市發(fā)展的重要功能空間,不僅積淀了深厚的歷史文化底蘊(yùn),更是城市重要的歷史、文化和旅游資源,城市內(nèi)河范圍包括河水、河道和兩岸景觀帶。隨著經(jīng)濟(jì)快速發(fā)展,城市化進(jìn)程不斷加快,生活污水、工業(yè)廢水的排放量逐漸增多,未經(jīng)處理便隨意排放至城市內(nèi)河,垃圾隨意堆放,使得河流及內(nèi)河水體受到嚴(yán)重污染,微生物種類減少,生態(tài)系統(tǒng)受到破壞,水體的自凈能力降低甚至喪失,河道周邊環(huán)境明顯惡化,甚至?xí)�出現(xiàn)臭氣,河道失去了原有的水環(huán)境功能。因此河道的治理逐漸引起重視并迫切需要治理。為了掌握整條河流的水質(zhì)狀況,解決城市內(nèi)河的污染問題并能提出有效合理的治理方案,需要對河道中水體的污染源、污染程度有較為客觀的了解,因此必須對城市內(nèi)河的水流進(jìn)行連續(xù)性監(jiān)測,并進(jìn)行水質(zhì)評價(jià)。保定府河是保定市重要河流之一,沿河兩岸具有生活區(qū)、市場、醫(yī)院、加油站、企業(yè)等,是一條典型的城市內(nèi)河,其河水水質(zhì)具有一定代表性；且府河位于白洋淀上游,是白洋淀源頭之一,府河的水質(zhì)對白洋淀的水質(zhì)有很大的影響,了解掌握府河水質(zhì)狀況,不僅對保定府河的整治、恢復(fù)河道功能提供數(shù)據(jù)依據(jù),對今后改善白洋淀水質(zhì)也具有一定的作用。第一,本研究是以保定府河為研究對象,選取蓮池南大街的南關(guān)大橋至東二環(huán)的焦莊橋段,確定了6個(gè)采樣斷面,對府河典型污染因子進(jìn)行了連續(xù)性監(jiān)測,采用人工方法對水溫、溶解氧、pH、濁度、化學(xué)需氧量、氨氮、總氮、總磷等幾項(xiàng)指標(biāo)進(jìn)行檢測,并對實(shí)驗(yàn)結(jié)果進(jìn)行記錄。第二,重點(diǎn)對化學(xué)需氧量、氨氮、總氮、總磷四項(xiàng)污染因子的檢測結(jié)果進(jìn)行了整理分析,從時(shí)間、空間、季節(jié)三個(gè)方面進(jìn)行總結(jié),得到了保定府河典型污染因子的時(shí)空變化規(guī)律,并研究了部分外界因素對水質(zhì)變化規(guī)律的影響。第三,結(jié)合實(shí)驗(yàn)數(shù)據(jù),及變化規(guī)律,應(yīng)用水質(zhì)標(biāo)識(shí)指數(shù)法對保定府河的水質(zhì)進(jìn)行評價(jià),包括對水質(zhì)級別的評判、綜合水質(zhì)的定性評價(jià)、綜合水質(zhì)隨時(shí)間、空間變化的評價(jià)。評價(jià)結(jié)果顯示保定府河水質(zhì)屬于劣V類水,且為重度污染。通過對保定府河水質(zhì)的連續(xù)性監(jiān)測和水質(zhì)評價(jià)可以更清楚、準(zhǔn)確的把握保定及周邊河流的水質(zhì)污染狀況,為河流整治以及合理開發(fā)利用和保護(hù)水資源奠定基礎(chǔ)。
[Abstract]:Since ancient times, urban inland river is the core of urban cultural heritage, commercial development and leisure and recreation. It is an important element of urban development and an important functional space to promote urban development. It not only accumulates profound historical and cultural details, but also plays an important role in urban development. It is also an important historical, cultural and tourist resource of the city. With the rapid development of economy and the acceleration of urbanization, the discharge of domestic sewage and industrial waste water is increasing gradually, which is discharged to urban inland rivers without treatment, and garbage is piled up at will, which makes the rivers and inland water bodies seriously polluted. The decrease of microbial species, the destruction of ecosystem, the decrease or even loss of self-purification ability of water body, the obvious deterioration of the surrounding environment of river, and even the appearance of odour, the river has lost its original function of water environment. Therefore, the regulation of the river gradually aroused attention and urgent need of governance. In order to grasp the water quality situation of the whole river, solve the pollution problem of the city inland river and put forward the effective and reasonable treatment plan, we need to have a more objective understanding of the pollution source and the pollution degree of the river water body. Therefore, continuous monitoring and evaluation of water quality must be carried out in urban inland rivers. Baoding Fu River is one of the important rivers in Baoding City. It has living areas, markets, hospitals, gas stations, enterprises, etc. It is a typical city inland river, and its water quality is representative, and the Fuhe River is located in the upper reaches of Baiyangdian Lake. The water quality of the Fuhe River has a great impact on the water quality of Baiyangdian Lake. Understanding the water quality situation of the Fuhe River not only provides a data basis for the regulation of the Fuhe River in Baoding, but also for the restoration of the river course function. It also plays a certain role in improving the water quality of Baiyangdian Lake in the future. First, this research takes Baoding Fuhe as the research object, selects the section of Jiaozhuang Bridge from Nanguan Bridge of Lianchi South Street to Dongerhuan Bridge, determines six sampling sections, and carries on the continuous monitoring to the typical pollution factors of Fuhe River. Water temperature, dissolved oxygen pH, turbidity, chemical oxygen demand, ammonia nitrogen and total phosphorus were detected by artificial method, and the experimental results were recorded. Second, the test results of four pollution factors, namely chemical oxygen demand, ammonia nitrogen and total phosphorus, were analyzed and summarized from three aspects: time, space and season. The temporal and spatial variation rules of typical pollution factors in Baoding Fuhe River were obtained, and the influence of some external factors on water quality was studied. Thirdly, the water quality of Baoding Fuhe River is evaluated by using the method of water quality marking index, which includes the evaluation of water quality grade, the qualitative evaluation of comprehensive water quality, and the evaluation of the change of water quality with time and space. The evaluation results show that the water quality of Baoding Fu River belongs to class V water and is seriously polluted. Through the continuous monitoring and evaluation of the water quality of the Fuhe River in Baoding, the pollution situation of the water quality of Baoding River and its surrounding rivers can be grasped more clearly and accurately, which will lay the foundation for river regulation, rational exploitation, utilization and protection of water resources.
