摘要:- 海綿城市建設(shè)逐漸強(qiáng)調(diào)系統(tǒng)治理的理念，通過多層級調(diào)控措施充分發(fā)揮海綿城市建設(shè)效果，但目前多層級調(diào)控措施缺乏細(xì)致的定量評估研究。為此，以北京城市副中心海綿城市試點(diǎn)區(qū)內(nèi)的一個已建合流制排水分區(qū)為例，基于InfoWorks ICM軟件構(gòu)建海綿城市建設(shè)區(qū)的精細(xì)化模型并開展情景模擬分析，定量評估不同層級的海綿城市建設(shè)效果。結(jié)果表明：①與海綿城市建設(shè)前相比，源頭調(diào)控、過程調(diào)控、末端調(diào)控方案的年徑流總量控制率由47.9%分別提升至51.4%、75.7%、75.2%，源頭-過程聯(lián)合調(diào)控方案和源頭-過程-末端聯(lián)合調(diào)控方案分別達(dá)到77.0%和84.5%；②在合流制排水分區(qū)計算年徑流總量控制率時，應(yīng)考慮在下游再生水廠處的間接溢流過程，以準(zhǔn)確評估海綿城市建設(shè)效果；③對于合流制排水分區(qū)，實(shí)施截污管過程調(diào)控工程后仍存在年均13次的合流制溢流事件，源頭-過程-末端聯(lián)合調(diào)控使得年均溢流頻次和溢流總量分別降低61.5%和52.5%；④受再生水廠處理能力的制約，多層級調(diào)控技術(shù)方案對排水分區(qū)下游再生水廠溢流事件的影響十分有限，年均溢流頻次和溢流總量僅降低6.2%和3.8%，有必要在排水分區(qū)尺度多層級海綿城市建設(shè)的基礎(chǔ)上，采用再生水廠提標(biāo)改造等一系列綜合性手段，實(shí)現(xiàn)區(qū)域尺度的海綿城市建設(shè)目標(biāo)。
- Abstract:
- Sponge city construction gradually emphasizes the concept of system governance, and its effect can be fully manifested through multi-level regulation measures. However, there is a lack of detailed quantitative evaluation research on multi-level regulation measures. A case study was carried out in a built-up combined drainage area in a sponge city pilot area of Beijing sub-center. A refined model of sponge city construction area based on InfoWorks ICM software was built, and the scenario simulation analysis was carried out. The effect of sponge city construction at different levels was quantitatively evaluated. Compared with the pre-sponge city, the volume capture ratio of annual runoff of source regulation, process control and terminal regulation schemes increased from 47.9% to 51.4%, 75.7% and 75.2% respectively, and those of the source-process and source-process-end combined control schemes reached 77.0% and 84.5%, respectively. When calculating volume capture ratio of annual runoff in the combined drainage zone, indirect overflow process of downstream reclaimed water plant should be considered to accurately evaluate the effect of sponge city construction. For the combined drainage zone, there were still 13 combined sewer overflow events per year after the implementation of the interception pipeline control project, and the source-process-end combined regulation could reduce the annual average overflow frequency and total overflow volume by 61.5% and 52.5%, respectively. Restricted by the treatment capacity of the reclaimed water plant, the impact of the multi-level regulation technical scheme on the overflow events of the downstream reclaimed water plant was very limited, and the annual average overflow frequency and total overflow volume only decreased by 6.2% and 3.8% respectively. Therefore, it was necessary to adopt a series of comprehensive means, such as construction of reclaimed water plant, to realize the construction target of sponge city at regional scale on the basis of multi-level sponge city construction of the drainage zone.
