Abstract

Abstract

Plants play an important part in water treatment function of constructed wetlands, in order to in-depth study the mechanism of salt-tolerant plants in purifying salt water and the role of synergistic filler, Canna indica L., Spartina alterniflora Loisel, Scirpus mariqueter, were chosen as the research objects, cooperating with compound fillers, to study the difference of pollutant removal effect in different, with different carbon to nitrogen ratios and salinity conditions. Simultaneously, we analyzed the enzyme activity in the plants in the experimental device, the diversity of microorganisms attached to the rhizosphere and the surface of the filler, and the microbial community structure. The results showed that: 1) constructed wetland could effectively treat coastal saline water. When HRT was 4 days, C/N was 3∶1 and salinity was 1‰, the removal effect of total nitrogen, total phosphorus and COD all reached their peaks; 2)the three salt-tolerant plants all showed certain salt-tolerance, among them, the purification effect of Spartina alterniflora Loisel was the best; 3)the removal rate of total nitrogen, total phosphorus and COD in the Spartina alterniflora Loisel device with new slag material was as high as 95.56%, 95.46% and 63.61%, respectively. At the same time, this device had rich microbial diversity. The device with new slag material optimized the ratio of microorganisms in an orderly manner, promote the synergistic purification of water by Spartina alterniflora and wetland functional microorganisms, which was conducive to take advantage of each bacterial species to prevent the malicious reproduction of the dominant bacterial species. The content of POD, CAT and soluble sugar in the Spartina alterniflora Loisel with the new slag material was higher than that of the other plants, and the content of propylene dione was the lowest, indicating that the plant suffered less harm from adversity and had strong anti-interference ability. This provided scientific basis and technical support for wetland plants to treat coastal or salt-containing sewage.
