In the present study, a new species of the genus Moniliformis species is described taxonomically in the mitochondrial genomic context. The parasite was found in a plateau zokor captured in a high-altitude area of Xiahe County of Gansu Province, China. The mitochondrial (mt) genome length of this new species was 14,066 bp comprising 36 genes and 2 additional non-coding regions (SNR and LNR), without atp8. The molecular phylogeny inferred by the cytochrome c oxidase subunit I gene (cox1) and the18S ribosomal RNA gene (18S rDNA) sequences showed that the parasite as a sister species to other Moniliformis spp. and was named Moniliformis sp. XH-2020. The phylogeny of the concatenated amino acid sequences of the 12 protein-coding genes (PCGs) showed Moniliformis sp. XH-2020 in the same cluster as Macracanthorhynchus hirudinaceus and Oncicola luehei confirming the cox1 and 18S rDNA phylogenetic inference. In addition, the entire mt genome sequenced in this study represents the first in the order Moniliformida, providing molecular material for further study of the phylogeny of the class Archiacanthocephala. Moreover, the species of this class, use arthropods as intermediate hosts and mammals as definitive hosts and are agents of acanthocephaliasis, a zoonosis in humans. Therefore, this study not only expands the host range among potential wild animal hosts for Archiacanthocephalans which is of great ecological and evolutionary significance but also has important significance for the research of zoonotic parasitic diseases.

Titanium dioxide (TiO2) film was prepared on activated carbon fibre (ACF) by hydrolysis technique, using sulphate titanium as raw material. Based on the techniques of photo catalytic degradation using TiO2/ACF, and 254nm UV-ray as the light sources, aqueous phenol solution of 40mg/L was photo catalytic decomposed over TiO2 film. The result showed that TiO2/ACF exhibited a degradation efficiency of 88.2% for phenol after 4h, while the condition of pH=7.5, the concentration of phenol is 40mg/L, power of ultraviolet light is 1.75W/L, and air quantity is 2.6mL/ (min·L). Analysis of photo degradation shows that the kinetics for photo catalytic degradation of phenol followed pseudo-first-order kinetic law, and the initial concentration of phenol, pH value, light intensity, air quantity and H2O2 concentration affected the photo catalytic degradation rates.

The article introduces the application of UASB-MBR system for landfill leachate treatment. The performance of UASB, MBR and total system was studied, respectively. The results showed that the integrated system performed with high efficiency, and the parameters such as CODCr, BOD5, NH3-N and SS of effluent can satisfy the class-III standards of the Standard for Pollution Control on the Landfill Site for Domestic Waste (GB 16899-1997).
