| 对红树植物塘处理农村生活污水的效果进行了中试研究。结果表明:红树植物在污染的淡水环境中能够很好生长,且对污染水体具有一定净化效果。在水力停留时间为3～4 d的条件下,流经红树塘的生活污水黑臭消失,浊度下降,透明度提高,出水DO浓度饱和度达到85%以上,进水COD、NH3-N和TP的去除效果分别达到73.3%、62.8%和36.7%。中试试验连续运行期间(约30 d),海桑株高平均增加0.11倍,基径平均增加0.035倍;桐花株高平均增加0.16倍,基径增加0.038倍。红树植物湿地处理系统作为一种低成本同时具有景观效果、重金属吸附等附加价值的污水处理技术,具有良好的推广应用前景。 |

| A pilot-scale experiment was conducted for evaluating the effects of mangrove plants in ponds on rural domestic wastewater disposal. Results showed that mangrove plants grew well in contaminated freshwater，and had a good cleaning effect on the polluted water; Under the condition that hydraulic retention time(HRT ) was 3-4 days，black smelly of the domestic wastewater which treated with mangrove plants disappeared and the turbidity lowered，moreover，the average removals of COD，NH3一N and TP were 73.3 % ,62.8 % and 36.7 %，respective1y. At the period of pilot-scale experiment(about 30 days )，for Sonneratia caseolaris，the average plant height increased by 0.11 times，and the average branch diameter increased by 0.035 times; and for Aegiceras corniculatum，the average plant height increased by 0. 16 times，and the average branch diameter increased by 0.038 times. As a low cost wastewater treatment technology，the mangrove wetland system also had a landscape effect and adsorption function of heavy metals. Therefore，the mangrove wetland system had a good application prospect. |
