【摘要】：當(dāng)前,我國(guó)一些地區(qū)水環(huán)境質(zhì)量差、水生態(tài)受損重、環(huán)境隱患多等問(wèn)題十分嚴(yán)重,這種現(xiàn)象在不具有完善監(jiān)管的小城鎮(zhèn)及農(nóng)村地區(qū)更為突出,嚴(yán)重影響和損害群眾健康,不利于社會(huì)經(jīng)濟(jì)持續(xù)發(fā)展。隨著國(guó)家新型城鎮(zhèn)化的發(fā)展,城鎮(zhèn)規(guī)模的不斷擴(kuò)大,城鎮(zhèn)污水處理規(guī)模將越來(lái)越大。本文主要針對(duì)現(xiàn)行我國(guó)村鎮(zhèn)污水處理工藝技術(shù)缺乏一定的技術(shù)規(guī)范,而城市污水處理設(shè)施存在不適用于村鎮(zhèn)的問(wèn)題,其他省市的污水處理工藝由于經(jīng)濟(jì)發(fā)展水平的不同,在湖南省內(nèi)也存在不適用,無(wú)法借鑒的問(wèn)題。本文結(jié)合湖南省目前的經(jīng)濟(jì)水平和村鎮(zhèn)污水處理現(xiàn)狀,對(duì)湖南省村鎮(zhèn)污水處理技術(shù)遴選優(yōu)化及運(yùn)營(yíng)管理模式進(jìn)行研究。本文主要的研究?jī)?nèi)容及成果如下：1、調(diào)研湖南省村鎮(zhèn)總體分布情況及經(jīng)濟(jì)概況、城鎮(zhèn)污水處理現(xiàn)狀,分析小城鎮(zhèn)及農(nóng)村主要污水水量、水質(zhì)特點(diǎn)、污水處理工藝、存在的問(wèn)題及處理對(duì)策。2、根據(jù)《湖南省村鎮(zhèn)污水處理設(shè)施建設(shè)實(shí)施導(dǎo)則》(征求意見(jiàn)稿)所推薦工藝以及現(xiàn)行運(yùn)用廣泛且比較穩(wěn)定的工藝,選擇4種較適合工藝：CRI、IBR、PASG以及改良氧化溝,在4種不同規(guī)模：0.2×104m3/d、0.5×104m3/d、1.0×104m3/d、 2.0×104m3/d下進(jìn)行技術(shù)和經(jīng)濟(jì)比較,采用層次分析法綜合評(píng)價(jià),得出推薦工藝。結(jié)論為在處理規(guī)模為500-5000m3/d時(shí),推薦采用IBR一體化生物反應(yīng)器技術(shù)；在處理規(guī)模為10000m3/d以上時(shí),推薦采用CR1人工快滲技術(shù)。3、針對(duì)湖南省小城鎮(zhèn)的具體情況,探討建設(shè)項(xiàng)目管理模式,湖南省村鎮(zhèn)污水處理前期融資及運(yùn)營(yíng)管理主要采取政府主導(dǎo)模式,經(jīng)濟(jì)較發(fā)達(dá)地區(qū)采取社會(huì)資本參與的BOT或DBO模式,通過(guò)政府對(duì)PPP模式的監(jiān)管和完善,再進(jìn)行推廣運(yùn)用。
[Abstract]:At present, the quality of water environment in some areas of our country is poor, the water ecology is seriously damaged, and there are many hidden dangers of the environment. This phenomenon is more prominent in small towns and rural areas that do not have perfect supervision and control, which seriously affects and harms the health of the masses. Not conducive to sustainable social and economic development. With the development of a new type of urbanization in the country, the scale of cities and towns continues to expand. The scale of urban sewage treatment will be larger and larger. This paper mainly aims at the lack of certain technical specifications for the current sewage treatment technology in villages and towns in our country, while the problems of urban sewage treatment facilities are not suitable for villages and towns. Due to the difference of economic development level in other provinces and cities, there are also some problems that can not be used for reference in Hunan Province. This paper combines the present economic level of Hunan Province and the present situation of sewage treatment in villages and towns. The main contents and achievements of this paper are as follows: 1. The general distribution and economic situation of villages and towns in Hunan Province, the present situation of sewage treatment in cities and towns, and the present situation of sewage treatment in cities and towns are investigated. This paper analyzes the characteristics of main sewage quantity, water quality, sewage treatment process in small towns and rural areas, The existing problems and treatment countermeasures. 2. According to the "guidelines for the Construction of sewage treatment facilities in villages and towns of Hunan Province" (draft of soliciting opinions) and the current widely used and relatively stable processes, Choose four more suitable processes: crai / IBRASG and improved oxidation ditch, compare the technology and economy at 0.5 脳 10 ~ 4 m ~ (3 / d) 0.5 脳 10 ~ (4) m ~ (3 / d), 2.0 脳 10 ~ (4) m ~ (3 / d), and evaluate it comprehensively by AHP. The conclusion is that when the scale of treatment is 500-5000m ~ (3 / d), The IBR integrated bioreactor technology is recommended, and when the scale of treatment is more than 10000m3 / d, CR1 artificial rapid infiltration technology .3is recommended to discuss the construction project management mode according to the concrete situation of small towns in Hunan Province. In Hunan province, the pre-stage financing and operation management of sewage treatment in villages and towns in Hunan Province mainly adopts the government-led mode, and the BOT or DBO model of social capital participation is adopted in the more developed areas, and then popularized and applied through the supervision and perfection of the PPP model by the government.
