As an important water resource, rainfall resources play a great role in human's production life and socio-economic development. In this paper, the northern typical city-Xi'an was taken as an example. On the basis of temporal and spatial distribution and utilization of water resources as well as the average annual precipitation statistics during 1999 to 2008 in Xi'an, the theory of rainfall frequency curve Pearson type III was established, and its economic value was estimated from aspects such as rainfall values, costs decrease and losses reduction. The results are as following. First, according to the city's theory of rainfall frequency curve Pearson type III, it is obtained that the average annual precipitation for 732.5mm and the total precipitation for 1.89×108m3 in wet years, the average annual precipitation for 511.8mm and total precipitation for 1.32×108m3 in normal years, the average annual precipitation for 359.6mm and the total precipitation for 0.93×108m3 in dry years. Second, in wet years, the value of rainfall resource itself is 8.26×108 yuan and the decreasing costs of the city's supply is 4.12×108 yuan; in normal years, the value of rainfall resource itself is 5.78×108 yuan and the decreasing costs of the city's supply is 2.88×108 yuan; in dry years, the value of rainfall resource itself is 4.06×108 yuan and the decreasing costs of the city's supply is 3.11×108 yuan, while the losses caused by water shortage decreased by 0.19×108 yuan. In view of the great utilized value of rainfall resources, the paper brings up an approach to use city rainfall effectively from catchments of city buildings, accumulation of City Park, and utilization of agricultural and other aspects, which has practical guiding significance for the exploitation and utilization of rain in future.

In order to fully find out distribution of Aquatic alligator weed in Nansi Lake drainage area, an on-site survey on typical inflow rivers of Nansi Lake and lake area was carried out in June 2010. Coverage of the weed at all the monitoring sections was given. Furthermore, one of the inflow rivers -Xiaosha River was chosen to give further investigation to acquaint growth condition of the alligator weed, from which we can get the harm of it to water environment and give countermeasure.

Polyvinyl alcohol (PVA) was commonly used in textile industry which could not be easily degraded by microorganism under the general conditions. As PVA was not readily biodegradable, its interference with conventional biological treatment methods meant the necessity of abiotic oxidative pretreatments before biological treatment. The relatively simple and flexible approach was O3/UV pretreatment. This study indicated that the treatment effect was obviously affected by the time, pH value, initial concentration of PVA and flow of O3. Under the conditions of O3/UV, with the indicator of Chemical Oxygen Demand (COD), the best conditions to degrade PVA were found. In this experiment, optimum reaction conditions for PVA pretreatment were obtained as following: 80 minutes for the reaction time, 0.5% for the concentration of PVA, pH=5 and 40L/h for the flow of O3. The removal ratio of COD was 95% when combined O3/UV with biodegradation treatment.

This paper researches the hydrogen and oxygen isotope compositions in precipitation in Baotou for eight years, and the meteoric water line was given: δD=6.36δ18O-5.21, which shows that some characteristics in the meteoric water line. The impact on precipitation isotope for the temperature and precipitation amount was analysed. The result shows that the impact factors of precipitation isotope was variational in the different seasons, and the degree of influence for several isotope effects is also various. The weighted-mean δD and δ18O values of precipitation tend to be more negative in January and December.

To improve our knowledge regarding the physical and biological processes relating the plankton ecology in typical subtropical estuaries, species composition, abundance and diversity of zooplankton were investigated during four cruises conducted in Zhanjiang Harbor waters, China, between Nov, 2008 and Feb, 2009. A total of 128 species of zooplankton and 9 species/assemblages of planktonic larvae were identified, including 49 species of Copepods, followed by Medusas (16 species), Protozoa (12 species), Decapods(10 species) and Chaetognatha(10 species), etc. The species/ assemblages that occurred in spring, summer, autumn and winter were 51, 45, 27, 59 species, respectively. In all, the abundance of zooplankton in the harbor inner waters was higher than that off the mouth of the Harbor waters, and the abundance was 1.1×102±1.5×102 individuals·m-3(ind. ·m-3), 1.5×102±2.3×102 ind·m-3, 4.1×10±3.4×10 ind·m-3, 5.6×10±5.0×10 ind·m-3 in spring, summer, autumn and winter, respectively. The seasonal turnover rate of dominant zooplankton species was higher than 63%, indicating relative large seasonal variation of the community structure. The Shannon-Winner diversity index averaged 3.08 annually, which increased from spring to summer, and decreased form autumn and winter to some extent. And the values of Evenness index and richness index showed similar trends as the diversity index seasonal variation. The value of community diversity was the highest in the middle waters (3.14), the second was in the mouth of the Harbor waters (3.10), and the last was in the coastal waters (2.99). Using step-wise regression method, the environmental adaption of zooplankton dominant species abundance analysis showed that the chlorophyll a, phytoplankton abundance, and sea water temperature had great effects on the dominant zooplankton species abundance, and the effects varied as the different species abundance, also indicating the differences in ecological niches among dominant zooplankton species.

In this paper, the chemical oxidation-coagulation method was used to treat oily wastewater containing high methanol and the influence factors of coagulation were studied. When pH value of wastewater was adjusted to 8.5, the dosage of H2O2, PAC and cationic polyacrylamide was 175 mg·l-1, 40 mg·l-1, 1.0 mg·l-1 respectively, the quality parameters of coagulated water such as pH value, contents of oil and suspended solid (SS) could achieve the feed-in require of methanol rectifying tower. In coagulation test, the dependence of floc sedimentation velocity on methanol concentration and ratio of Oil/SS was studied, the results showed that the sedimentation velocity of floc decreased with increasing methanol concentration, and the velocity varied slowly and tended to keep stable when the methanol concentration was over 53.0%; While Oil/SS<;6, the sedimentation velocity of floc decreased with increasing Oil/SS. Once oil/SS>;6, the floc floated upward due to higher condensate-oil concentration.

In this study, we developed a bio-diatomite dynamic membrane reactor (BDDMR) as a new water treatment technology. The effectiveness of this new system was evaluated by investigating the removal effect of pollutants, and the three-dimensional excitation and emission matrix fluorescence spectroscopy (3D-EEM) was employed to characterize the chemical nature of dissolved organic matter (DOM) in influent, and effluent of BDDMR at pilot-scale in continuous-flow mode at a hydraulic retention time of 8 h. Experimental results indicated that the system was better to remove pollutant, and two peaks could be observed in all DOM in various origins, showing that the aromatic protein-like in every substances, could be removed effectively. The results also illustrated that the system could be able to remove the pollutants such as protein-like substances and soluble microbial byproduct-like material.
