【摘要】：近三十年來(lái)國(guó)民經(jīng)濟(jì)與社會(huì)的方方面面都取得了跨越式的進(jìn)步,可這是一味追求經(jīng)濟(jì)增速的、有代價(jià)的發(fā)展模式,不可避免地對(duì)水環(huán)境帶來(lái)了極大的傷害,隨著全國(guó)每年排污量的不斷上漲,國(guó)家新型排污標(biāo)準(zhǔn)的連續(xù)頒布,已建成的大部分傳統(tǒng)污水處理廠都面臨出水不達(dá)標(biāo)需要提標(biāo)改造的問題,污水處理中活性污泥法也早已被世界各國(guó)應(yīng)用的淋漓盡致,需要對(duì)其進(jìn)行創(chuàng)新和改良。本文在大量閱讀文獻(xiàn)的基礎(chǔ)上,對(duì)國(guó)內(nèi)水污染狀況做了簡(jiǎn)要介紹,概述了城鎮(zhèn)污水處理廠概況,對(duì)主要污水處理技術(shù)的發(fā)展進(jìn)行了總結(jié)歸納。由淺入深地介紹了新型ARES(光化合微生物復(fù)合系統(tǒng))具體工藝流程,由理論發(fā)展到實(shí)際工程系統(tǒng)地闡釋了ARES生態(tài)能污水處理系統(tǒng),深入剖析了光合細(xì)菌與活性污泥微生物聯(lián)合在污水處理中脫氮除磷的機(jī)理;分別計(jì)算比較了利用ARES系統(tǒng)以及A2/O工藝升級(jí)改造藍(lán)田縣污水處理廠時(shí),在工藝流程、污染物去除效率、經(jīng)濟(jì)技術(shù)等方面的可行性,以大量詳實(shí)的理論計(jì)算數(shù)據(jù)對(duì)比了ARES工藝相比于其他污水處理方法在提標(biāo)改造時(shí)的巨大優(yōu)勢(shì)。本文最后以ARES第一個(gè)樣板工程—山東濟(jì)寧污水處理廠的成功應(yīng)用為工程實(shí)例,計(jì)算分析出在該水廠應(yīng)用ARES系統(tǒng)后,生產(chǎn)運(yùn)營(yíng)過(guò)程中產(chǎn)生的明顯經(jīng)濟(jì)效益。通過(guò)對(duì)比計(jì)算研究表明:將ARES生態(tài)能污水處理系統(tǒng)應(yīng)用于藍(lán)田污水廠提標(biāo)改造時(shí),前期投資可減少178.95萬(wàn)元(相對(duì)A2/O工藝),后期運(yùn)營(yíng)費(fèi)用同步減少,投資回報(bào)期短(5.2年)等經(jīng)濟(jì)技術(shù)優(yōu)勢(shì);以山東濟(jì)寧污水廠為例,ARES系統(tǒng)在運(yùn)營(yíng)時(shí)全廠無(wú)臭味的產(chǎn)生、年度排泥總量減少50%以上、污水廠全年減少電費(fèi)957573.12元,投藥量和人工費(fèi)降低,降低直接運(yùn)營(yíng)成本30%以上;實(shí)際應(yīng)用中停用了中間沉淀池以及降低了濾布濾池負(fù)荷;使得濟(jì)寧污水廠污水處理成本降低0.2元/噸;出水滿足《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》中一級(jí)A的排放標(biāo)準(zhǔn);處理后中水已經(jīng)實(shí)現(xiàn)部分向工業(yè)供水的有償回用,是具有明顯優(yōu)勢(shì)的具有極大發(fā)展?jié)摿Φ男乱淮鬯幚硇录夹g(shù)。
[Abstract]:In the past 30 years, all aspects of the national economy and society have made leapfrog progress, but this is a blind pursuit of economic growth, the development model with a price, which inevitably brings great harm to the water environment. With the increase of annual sewage discharge and the continuous promulgation of national new sewage standards, most of the traditional sewage treatment plants have been faced with the problem that the effluent is not up to the standard and need to be upgraded. Activated sludge process in sewage treatment has already been used in many countries all over the world, which needs to be innovated and improved. Based on a lot of literature, this paper briefly introduces the situation of domestic water pollution. The general situation of urban sewage treatment plant is summarized and the development of main sewage treatment technology is summarized. The concrete technological process of new type ARES (photochemical microorganism compound system) is introduced. The ARES ecological energy wastewater treatment system was systematically explained from theory to practice, and the mechanism of nitrogen and phosphorus removal by photosynthetic bacteria and activated sludge microorganism in wastewater treatment was deeply analyzed. The feasibility of upgrading the wastewater treatment plant of Lantian County by using ARES system and A2 / O process was calculated and compared in the aspects of technological process, pollutant removal efficiency, economy and technology, etc. A large number of detailed theoretical calculation data are used to compare the great advantages of ARES process compared with other sewage treatment methods in standard raising and revamping. Finally, the first model project of ARES, Shandong Jining sewage treatment Plant, is used in this paper. Is successfully applied as an engineering example. The application of ARES system in this water plant is calculated and analyzed. Through comparison and calculation, it is shown that the ARES ecological energy wastewater treatment system is applied to the upgrading of the standard of Lantian sewage treatment plant. The pre-investment can be reduced by one million seven hundred and eighty-nine thousand and five hundred yuan (compared with A _ 2 / O process, the late operating expenses are reduced simultaneously, the investment return period is short (5.2 years) and other economic and technological advantages; " Taking Shandong Jining sewage plant as an example, the whole plant has no stink in operation. The total amount of sludge discharged annually is reduced by more than 50%, and the annual electricity cost of sewage treatment plant is reduced by 957573.12 yuan. The dosage and labor cost are reduced, and the direct operating cost is reduced by more than 30%; In practical application, the intermediate sedimentation tank was stopped and the load of filter cloth filter was reduced. The cost of sewage treatment in Jining sewage treatment plant was reduced by 0.2 yuan per ton; The effluent meets the discharge standard of the first class A of the pollutant discharge standard of the municipal wastewater treatment plant; After treatment, the reclaimed water has been partly reused for industrial water supply. It is a new generation of sewage treatment technology with great development potential with obvious advantages.
