- 摘要:
- 通過調(diào)研城市供熱經(jīng)營企業(yè)生產(chǎn)需求和類比國內(nèi)既有相關(guān)工程實(shí)例，認(rèn)為滿足《城鎮(zhèn)污水處理廠污染物排放標(biāo)準(zhǔn)》(GB 18918—2002)一級A標(biāo)準(zhǔn)的城鎮(zhèn)污水處理廠排水經(jīng)處理后可作為同時(shí)滿足《工業(yè)循環(huán)冷卻水處理設(shè)計(jì)規(guī)范》(GB/T 50050—2017)、《城市污水再生利用 工業(yè)用水水質(zhì)》(GB/T 19923—2005)和《采暖空調(diào)系統(tǒng)水質(zhì)》(GB/T 29044—2012)的城市集中供熱管網(wǎng)補(bǔ)充水回用，但水處理工程的選址與規(guī)模應(yīng)與城市集中供熱管網(wǎng)建設(shè)的具體規(guī)劃相契合。城市供熱經(jīng)營企業(yè)尚需搭建24項(xiàng)水質(zhì)指標(biāo)的全面監(jiān)測技術(shù)平臺(tái)；研發(fā)水處理成本與直接購買工業(yè)用自來水相比能夠形成明顯價(jià)格優(yōu)勢的新工藝；采用經(jīng)濟(jì)適用的緩蝕阻垢殺生劑配方以降低集中供熱管網(wǎng)維護(hù)費(fèi)；因地制宜地開展全生命周期經(jīng)濟(jì)評價(jià)以權(quán)衡管材基建費(fèi)用與緩蝕阻垢殺生劑運(yùn)營費(fèi)用的取舍，以謀求我國嚴(yán)寒地區(qū)和寒冷地區(qū)的冬季供熱真正實(shí)現(xiàn)節(jié)能減排。
- Abstract:
- Demand for supplementary water from district heating (DH) management enterprises and relevant domestic engineering cases were investigated, and thus it was suggested that the treated drainage of municipal wastewater treatment plant (WWTP), which was satisfied with the first class A criteria of GB 18918-2002, and which met the norms of GB/T 50050-2017, GB/T 19923-2005 and GB/T 29044-2012 simultaneously, could be reused as the supplementary water of DH network. The locations and dimensions of the water treatment projects should correspond to construction programme of the DH network. In order to truly implement energy saving & emission reduction for heating supply in freezing and cold regions in China, DH management enterprises still need monitoring setups for the 24 water quality indices, a new water reuse technology of which processing cost is much lower than the price of tap water for industry use, an application of suitable scale, corrosion and microorganism inhibitors reducing the maintenance expense of the DH network, and a launch of the total life cycle economic assessment for trading off the capital expenditure of pipes against the operating expenses of inhibitors, suiting to the local conditions.
