- 摘要:
- 在補(bǔ)充再生水的模擬景觀(guān)水體中采用黃菖蒲生物浮床，并引入網(wǎng)箱種植的水綿構(gòu)建水綿強(qiáng)化浮床，從而探討中低溫條件下水綿強(qiáng)化浮床對(duì)再生水補(bǔ)給的城市景觀(guān)水體水質(zhì)的凈化效果。試驗(yàn)結(jié)果表明，水綿對(duì)銅綠微囊藻的生長(zhǎng)具有明顯的抑制作用，水綿強(qiáng)化浮床可以控制再生水補(bǔ)給的景觀(guān)水體中的藻密度和葉綠素a（Chl-a）濃度，其在中低溫連續(xù)運(yùn)行60 d過(guò)程中，水綿強(qiáng)化浮床水體的藻密度和Chl-a濃度均值分別為1.57×104個(gè)/mL和5.59 μg/L，為浮床水體對(duì)應(yīng)值的34.28%和54.54%，為空白水體對(duì)應(yīng)值的4.89%和14.44%。同時(shí)，水綿強(qiáng)化浮床對(duì)再生水補(bǔ)給的模擬景觀(guān)水體中的氮和磷具有較好的去除效果，在TN、NH+4-N和NO-3-N的本底濃度分別為7.52、1.71、5.53 mg/L條件下，運(yùn)行60 d后其對(duì)應(yīng)的濃度分別降低至0.20、0.08、0.06 mg/L；當(dāng)TP和PO3-4-P的本底濃度分別為0.75、0.70 mg/L時(shí)，運(yùn)行60 d后其對(duì)應(yīng)的濃度分別降低至0.01 mg/L和檢測(cè)限以下。因此，水綿強(qiáng)化浮床對(duì)再生水補(bǔ)給的景觀(guān)水體中低溫階段的水質(zhì)凈化及藻類(lèi)控制效果明顯，可有效控制該類(lèi)水體的富營(yíng)養(yǎng)化，是一種高效的景觀(guān)水體水質(zhì)控制方法。
- Abstract:
- A floating bed system vegetated with calamus was built in a simulated landscape water supplied with reclaimed water, and an enhanced floating bed system with Spirogyra planted in a cage was established to explore its purification effect on the simulated urban landscape water under intermediatelow temperature. The results indicated that Spirogyra had obvious inhibitory effect on growth of Microcystis aeruginosa and the enhanced floating bed could reduce algae density and chlorophylla (Chl-a) concentration of simulated urban landscape water. During 60 days of continuous operation under intermediate low temperature, the average values of algae density and Chl a concentration in the enhanced floating bed water were 1.57×104 cells/mL and 5.59 μg/L, which were 34.28% and 54.54% of the corresponding values in the floating bed water, and 4.89% and 14.44% of that in the controlling water. On the other hand, the enhanced Spirogyra floating bed had a high removal efficiency of nitrogen and phosphorus in the simulated urban landscape water. The concentrations of TN, NH+4-N and NO-3-N were reduced to 0.20 mg/L, 0.08 mg/L and 0.06 mg/L after 60 days of operation when the corresponding background concentrations were 7.52 mg/L, 1.71 mg/L and 5.53 mg/L, respectively. Meanwhile, the concentrations of TP and PO3-4-P were reduced to 0.01 mg/L and below the detection limit after 60 days of operation when the corresponding background concentrations were 0.75 mg/L and 0.70 mg/L. In a word, the enhanced Spirogyra floating bed could effectively improve the water quality and inhibit algae growth of urban landscape water supplied with reclaimed water. Thus, the enhanced Spirogyra floating bed is an efficient method of controlling the landscape water quality, which can effectively prevent eutrophication of the urban landscape water.
