经过 1a的实验结果表明 :生活污水的排放使红树林湿地系统的水体DO值下降 ,BOD5和CODMn值升高 ,TN、TP 增高。排污对红树林植物秋茄、桐花树、白骨壤的生长 (包括树高、茎径和生物量的年增长量以及年净生产力 )有促进作用 ,同时使秋茄、桐花树的年凋落物量增加而白骨壤的年凋落物量减少。表明红树植物对生活污水的适应能力较强 ,利用红树林湿地系统净化生活污水有一定可行性
The experimental results after 1a showed that the discharge of domestic sewage reduced the DO of mangrove wetland system, the values of BOD5 and CODMn increased, and the TN and TP increased. Sewage discharge can promote the growth of mangrove plant candel, Aegiceras corniculatum and Avicennia marina, including the annual growth of tree height, stem diameter and biomass as well as annual net productivity, and increase the annual litterfall of Kandelia candel and Aegiceras corniculatum The amount of annual litter reduced Avicennia marina. The results showed that the mangrove plants have strong adaptability to domestic sewage and it is feasible to purify sewage with mangrove wetland system
