【摘要】：造紙工業(yè)是一個(gè)投資大、能耗高并且對環(huán)境會造成嚴(yán)重污染的產(chǎn)業(yè)。與發(fā)達(dá)國家造紙行業(yè)相比，我國造紙工業(yè)存在水資源消耗量大、利用率不高的問題，對環(huán)境、資源造成了巨大的破壞。造紙工業(yè)必須采取措施更好的利用日益緊缺的水資源，降低工業(yè)污水的排放對水體的污染。 2008年6月國家環(huán)境保護(hù)部發(fā)布了《紙漿造紙工業(yè)污染物排放標(biāo)準(zhǔn)》（GB3544-2008），代替《造紙工業(yè)水污染物排放標(biāo)準(zhǔn)》（GB3544-2001），新標(biāo)準(zhǔn)要求現(xiàn)有紙漿造紙企業(yè)執(zhí)行更為嚴(yán)格的排放標(biāo)準(zhǔn)。為了進(jìn)一步減少環(huán)境污染、實(shí)現(xiàn)企業(yè)的可持續(xù)目標(biāo)，造紙業(yè)污水處理系統(tǒng)面臨著迫在眉睫的升級改造的問題。 本論文通過對國內(nèi)外造紙工業(yè)污水處理工藝的比較，，結(jié)合輝南縣輝發(fā)城造紙廠的的實(shí)際情況，設(shè)計(jì)了輝發(fā)城造紙廠升級改造的工藝流程，并對此工藝進(jìn)行了環(huán)境影響評價(jià)和投資估算分析。 本文的主要內(nèi)容包括： （1）通過查閱相關(guān)文獻(xiàn)資料，比較了國內(nèi)外造紙工業(yè)對水資源的污染情況，從造紙工業(yè)污水的來源、危害分析了造紙廢水污染的特點(diǎn)。 （2）對吉林省輝南縣輝發(fā)城造紙廠的基本情況做了概述，并分析了該造紙廠污水處理的現(xiàn)狀，在查閱大量相關(guān)文獻(xiàn)資料的基礎(chǔ)上，結(jié)合國內(nèi)外眾多的工程實(shí)例，提出了污水系統(tǒng)升級改造工程采用SBR+絮凝沉淀的設(shè)計(jì)方案，并對工藝流程中的各個(gè)構(gòu)筑物包括機(jī)構(gòu)設(shè)計(jì)、建筑設(shè)計(jì)、采暖設(shè)計(jì)和管線防腐等進(jìn)行了細(xì)化。 （3）根據(jù)輝發(fā)城造紙廠的實(shí)際情況，對本次升級改造項(xiàng)目進(jìn)行了簡單的環(huán)境影響評價(jià)，并對此次升級改造項(xiàng)目的處理效果-效益進(jìn)行了分析，最后對本項(xiàng)目的投資進(jìn)行了估算。
[Abstract]:Paper industry is an industry with large investment, high energy consumption and serious environmental pollution. Compared with the paper industry in developed countries, China's paper industry has the problems of large consumption of water resources and low utilization ratio. The paper industry must take measures to make better use of the increasingly scarce water resources and reduce the pollution caused by the discharge of industrial sewage to the water body. In June 2008, the State Ministry of Environmental Protection issued the "Pollutant discharge Standard for Pulp and Paper Industry" GB3544-2008). Instead of the discharge Standard of Water pollutants in Papermaking Industry, GB3544-2001, the new standard requires existing pulp and paper enterprises to implement more stringent emission standards in order to further reduce environmental pollution. To achieve the sustainable goal of the enterprise, the paper industry wastewater treatment system is faced with the urgent problem of upgrading and transformation. Based on the comparison of domestic and foreign wastewater treatment processes in paper industry, combined with the actual situation of Huifa City Paper Factory in Huinan County, the technological process of upgrading and upgrading of Huifa City Paper Mill was designed. The environmental impact assessment and investment estimation analysis of this process are also carried out. The main contents of this paper include: In this paper, the pollution of water resources in paper industry at home and abroad is compared, and the pollution characteristics of papermaking wastewater are analyzed from the source and harm of waste water in papermaking industry. This paper summarizes the basic situation of Huifa City Paper Mill in Huinan County, Jilin Province, and analyzes the present situation of sewage treatment of the paper mill, on the basis of consulting a large number of related documents. Combined with many engineering examples at home and abroad, this paper puts forward the design scheme of sewage system upgrading project using SBR flocculation sedimentation, and designs each structure including mechanism design and architectural design in the process flow. The heating design and pipeline anticorrosion were refined. 3) according to the actual situation of Huifa City Paper Mill, a simple environmental impact assessment is carried out on this upgrade project, and the effect-benefit of the upgrading project is analyzed. Finally, the investment of this project is estimated.
