【摘要】：我國(guó)工業(yè)用水主要集中在五大行業(yè)，即火電、石油化工、冶金、造紙和紡織。這五個(gè)行業(yè)的總?cè)∷空既珖?guó)工業(yè)取水量的2/3，其中火力發(fā)電行業(yè)是取水量最大的行業(yè)�；痣姀S需要有足夠的水量和一定的水質(zhì)來(lái)保證生產(chǎn)，而內(nèi)蒙古地區(qū)的火力發(fā)電廠在用水效率和水平方面，與國(guó)外先進(jìn)國(guó)家以及國(guó)內(nèi)發(fā)達(dá)地區(qū)相比都存在著較大的差距；人的節(jié)水意識(shí)淡薄，缺乏有效的管理手段和方法，普遍存在不同程度的用水浪費(fèi)現(xiàn)象。因此在內(nèi)蒙古特別是中西部地區(qū)火力發(fā)電廠大力開展節(jié)水，重要性不言而喻，如何能夠科學(xué)、合理地使用水資源，，是關(guān)系到地區(qū)經(jīng)濟(jì)發(fā)展是否可持續(xù)，區(qū)域生態(tài)環(huán)境能否保持的核心問(wèn)題。 之前對(duì)于火力發(fā)電企業(yè)節(jié)水方面的研究，只是較為側(cè)重于廢水的零排放以及節(jié)水用水技術(shù)這些層面，而有關(guān)廢水回用處理及火電企業(yè)的各個(gè)系統(tǒng)用水的技術(shù)并沒有較深層次的研究。在本文中，我們以內(nèi)蒙古海勃灣電廠作為研究對(duì)象，基于經(jīng)濟(jì)合理、技術(shù)可行等相關(guān)原則，通過(guò)對(duì)火力發(fā)電企業(yè)用水節(jié)水的基本政策和節(jié)水技術(shù)的總結(jié)歸納，同時(shí)分析了用水現(xiàn)狀和節(jié)水潛力，并提出了火力發(fā)電企業(yè)節(jié)水策略的技術(shù)優(yōu)化途徑，最后對(duì)該電廠進(jìn)行了技術(shù)經(jīng)濟(jì)評(píng)價(jià)，為今后火力發(fā)電企業(yè)節(jié)水模型的實(shí)施以及有效的推廣奠定了基礎(chǔ)。
[Abstract]:China's industrial water is mainly concentrated in five industries, that is, thermal power, petrochemical, metallurgy, paper and textile. The total water intake of these five industries accounts for 2 / 3 of the national industrial water intake, among which the thermal power industry is the largest. The thermal power plant needs enough water quantity and certain water quality to ensure production, but the thermal power plant in Inner Mongolia has a big gap compared with foreign advanced countries and domestic developed regions in the efficiency and level of water use. People's consciousness of saving water is weak, lack of effective management means and methods, and there is a phenomenon of water waste in different degrees. Therefore, in Inner Mongolia, especially in the central and western regions of thermal power plants, the importance of vigorously developing water saving is self-evident. How to use water resources scientifically and rationally is related to the sustainability of regional economic development. The core problem of whether the regional ecological environment can be maintained. Previous research on water saving in thermal power plants has only focused on zero discharge of wastewater and water saving technologies. However, there is no deep research on wastewater reuse treatment and water use in thermal power plant. In this paper, we take Haibiewan Power Plant in Inner Mongolia as the research object, based on the relevant principles such as economic reasonableness, feasible technology and so on, through summarizing the basic policy and water-saving technology of coal-fired power enterprises. At the same time, the present situation of water use and water saving potential are analyzed, and the technical optimization approach of water-saving strategy of thermal power plant is put forward. Finally, the technical and economic evaluation of the power plant is carried out. It lays a foundation for the implementation and effective popularization of water-saving model for thermal power enterprises in the future.
