- Title:
- Engineering Application of Municipal Wastewater Treatment Plants Effluent Reused for Supplementary Water of District Heating Network
- 關鍵詞:
- 城市集中供熱管網; 補充水; 城鎮污水處理廠排水回用; 循環冷卻水
- Keywords:
- urban district heating network; supplementary water; reuse of drainage of municipal wastewater treatment plant; recirculating cooling water
- 摘要:
- 通過調研城市供熱經營企業生產需求和類比國內既有相關工程實例，認為滿足《城鎮污水處理廠污染物排放標準》(GB 18918—2002)一級A標準的城鎮污水處理廠排水經處理后可作為同時滿足《工業循環冷卻水處理設計規范》(GB/T 50050—2017)、《城市污水再生利用 工業用水水質》(GB/T 19923—2005)和《采暖空調系統水質》(GB/T 29044—2012)的城市集中供熱管網補充水回用，但水處理工程的選址與規模應與城市集中供熱管網建設的具體規劃相契合。城市供熱經營企業尚需搭建24項水質指標的全面監測技術平臺；研發水處理成本與直接購買工業用自來水相比能夠形成明顯價格優勢的新工藝；采用經濟適用的緩蝕阻垢殺生劑配方以降低集中供熱管網維護費；因地制宜地開展全生命周期經濟評價以權衡管材基建費用與緩蝕阻垢殺生劑運營費用的取舍，以謀求我國嚴寒地區和寒冷地區的冬季供熱真正實現節能減排。
- 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.
