【摘要】：【目的】研究狐尾藻對不同濃度養(yǎng)殖廢水的凈化效果,為推廣新型水生植物品種在處理養(yǎng)殖廢棄物中的應(yīng)用提供參考依據(jù)�！痉椒ā繉⒑苍逋斗庞诜謩e經(jīng)過養(yǎng)殖場1、2、3、4和5級處理的廢水中培養(yǎng),在試驗(yàn)期間測量各級廢水氨氮(NH4+-N)、總氮(TN)、總磷(TP)、固體懸浮物(SS)及化學(xué)需氧量(COD)的濃度,繪制其變化曲線,計(jì)算污染物的去除率。【結(jié)果】經(jīng)1~5級處理后的養(yǎng)殖廢水中NH4+-N、TN、TP、SS及COD濃度均呈試驗(yàn)前期快速下降、后期緩慢降低的變化趨勢。至試驗(yàn)結(jié)束時,各級廢水中NH4+-N的總平均去除率最高,達(dá)94.5%;TP的平均去除率相對較低,為74.6%;TN、SS和COD的總平均去除率分別為84.5%、81.3%和79.1%�！窘Y(jié)論】狐尾藻能有效去除養(yǎng)殖廢水中NH4+-N、TN、TP、SS及COD等污染物,改善水質(zhì)環(huán)境,在治理和修復(fù)污染水體方面具有良好的應(yīng)用前景。
[Abstract]:[objective] to study the purifying effect of Sargassum vulgaris on different concentration of culture wastewater. To provide the reference for popularizing the application of new aquatic plant varieties in the treatment of aquaculture waste. [methods] the alga was cultured in the waste water treated with grade 1, 2, 3, 4 and 5 of the farm, respectively. During the experiment, the concentrations of NH _ 4-N _ 4, TNN, TPN, SS and COD were measured, and the curves were plotted. The removal rate of pollutants was calculated. [results] the concentrations of NH4 -NN, TNN, TPSS and COD in the culture wastewater treated with 1 ~ 5 grade were decreased rapidly in the early stage of the experiment, and slowly decreased in the later stage. At the end of the experiment, the concentration of NH4 -NX, TNT, TPSS and COD decreased slowly at the end of the experiment. The total average removal rate of NH4 -N was the highest in all levels of wastewater, and the average removal rate of 94.5% TP was relatively low. The total average removal rates of NH4 and COD were 84.51.3% and 79.1%, respectively. [conclusion] P. vulgaris can effectively remove the pollutants such as NH4 -NTNTPSS and COD in the culture wastewater. The improvement of water quality environment has a good application prospect in the treatment and remediation of polluted water.
