As the Cu2+ in EDTA-Cu wastewater has too high concentration to remove with general method and is in a complex state, and its handling is the difficult part in environmental engineering, we try to use synchronous Oxidation Treatment in EDTA-Cu wastewater with high ferrite salt and have achieved good results. Preparation of Na2FeO4 as an oxidant on the spot can not only solve the problem of high cost, but simplify the process of disposal. Measured by the removal rates of Cu2+ as criteria, the effect of three important factors are studied, including ph, dosage and reaction time, then corresponding optimal parameters can be acquired by the orthogonal test. The results show that the removal rate of Cu2+ can be up to 99.1% in such experimental conditions that pH=14, reaction time = 30min and dosage = 300mg/L, and the concentration of Cu2+ is less than 0.49mg/L in the treated wastewater, which also meets the national discharge standards of class I.

Depth profiles of particulate matter and elements in particulate matter collected from two typical resident buildings of a 7-storey building (B1) and a 24-storey building (B2) in the city of Xi'an, China were investigated. Physical characterization and chemical analysis of the settled dusts collected at different heights of B1 and B2 in April 2009 showed that (1) the volume percent for the fine particles (particle size <;10.5 μm) of the settled dusts was 26%-31% from B1 and 27%-38% from B2. The depth profiles showed an inversion layer at ~21 m above ground: when lower than 21 m, the volume percent for the fine particles increased while that of the coarse particles (particle size >;10.5 μm) decreased with increasing height; when higher than 21 m, the distribution patterns reversed. The re-suspension by wind serious impact on the dusts collect by dry traps than collected by wet traps; (2) the concentrations for 8 out of 25 elements analyzed were 3-15 times higher relative to soil background values in China. The contents of two of the elements analyzed, Mo and S, in the sample collected at 12 m, were 3 and 18 times, respectively, the value at 66m in B2. The content distribution for the remaining elements appeared to be height independent. Work is in process on persistent organic pollutants in the settled dusts.

An ethanol-soluble crude flavonoid, obtained from corn pollen, was classified and purified through AB-8 macroporous resin column (1200×120mm), flowed by eluting the column with 40% ethanol, 60% ethanol, 80% ethanol. They have names corresponding to FPM-A, FPM-B and FPM-C. Polysaccharides also were extracted by hot-water from corn pollen and precipitated with 60% ethanol, 80% ethanol and 95% ethanol in turn, respectively noted as PPM-A, PPM-B and PPM-C. Further, their antioxidant capacities in vitro were evaluated by the assays of reducing power, scavenging hydroxyl radical, and scavenging superoxide radical. Antioxidant activity tests revealed that fractions all showed good capability of antioxidant. In the meanwhile, FPM-B and PPM-B exhibited the better potential for antioxidant activity. It suggests that corn pollen may be considered as a potential candidate for the natural antioxidants and possible health-promoting functional foods.

A pot experiment was conducted to study the effects of controlled-release fertilizers and ratio of N to K on growth of mauls seedlings, interaction, P and K use efficiency and nitrogen balance. The results showed that the release of controlled-release nutritional elements accorded with requirement of mauls seedlings. Controlled release N increased use efficiency of K, and controlled release K increased use efficiency of N. Dry weight of plant, use efficiency of P and K were in the order of controlled-release N and K fertilizer (NK) >; controlled release N fertilizer (CN) >; soluble fertilizer (SF). The level of K had no effect on height and stem diameter, but affected the dry weight. The use efficiency of P was increased with more controlled-release K applied, but the dosage of common K had no effect on P use efficiency. The use efficiency of K was decreased with more controlled release K applied. Nitrogen use efficiency was in the order of NK>;CN>;SF, while loss ratio was in the reverse order. There was no difference in residual ratio between NK and CN but higher than SF. The dosage of controlled-release K had effect on use efficiency and loss ratio of N, while had no effect on residual ratio of N.

The characteristics of macroporous adsorption resins with different polarity on adsorption and isolation property of total flavonoids from Prunella Vulgaris Linn were performed by static and dynamic adsorption tests. Subsequently, the free radical and antimicrobial capacity of purified flavonoids were also evaluated. The results exhibited that AB-8 resin had higher absorption and desorption capacity. The optimum technology parameters of adsorption and separation were sample solution volume 3BV, sample solution concentration 1.6 mg/ml, velocity of flow 6BV/h. Adsorbted total flavonoids could be desorbed by 70% alcohol at flow rate 6BV/h, dosage 6BV. Compared to the 41.58% of total flavonoids in crude extracts, the recovery and purity of total flavonoids were 92.36% and 89.09% respectively. The DPPH radical scavenging activity of purified flavonoids was similar to antiscorbic acid which was much higher than that of butylated hydroxytoluene. It aslo had strong antimicrobial activity on Staphylococcus aureus and Escherichia coli (the diameters of the antimicrobial circle were 23.4mm and 21.2mm respectively). But it had no effect on Yeast and Aspergillus niger.

Comparing with point source pollution, the non-point source (NPS) one, particularly from agricultural activities, has been dominant in many countries presently, causing nutrient loss, aqueous systems damaging, and eutrophication. One of the key elements responsible for it is nitrogen (N). The Yongding River is an important watershed in North China, which relates to Beijing City (capital of China), Tianjing City and Hebei, Inner Mongolia, Shanxi province. This study, reveals agricultural NPS pollution of Yongding River in Hebei province. The resource, loading and distribution of agricultural NPS pollution are simulated and analyzed in the paper based on remoting sense and geographic information system by export coefficient model (ECM). The result indicates that the total NPS-N loading of the research area was 5.68 × 104 t in 2008. The loading of agricultural landuse was 4.38 × 104 t, and that of rural life and livestock feeding was 0.90 × 104 t and 0.40 × 104 t respectively. As far as the spacial distribution of the loading is concerned, farm lands (sloping areas especially), villages and hoggeries were areas with heavy pollution. In the conclusion, it is suggested that the methods of agricultural landuse and N fertilizer utilization should be improved as well as the treatment efficiency of waster water and solid waste should be increased.

The mechanism of Fe3+catalyzed oxidation of S(IV) is the combination of catalyzed oxidation and radical reaction, the O2- produced from the oxygen in solution plays a very important role for the oxidation of S(IV),which determines the mode and process of the reaction. In the absence of catalyst, the oxidation of S(IV) is relatively slow in the liquid, the reaction rate depends on the concentration of dissolved oxygen. When pH is 2.80, the reaction rate constant of Fe3+ catalyzed oxidation of S(IV) is 588 (mol / L)-1 · s-1.). The study results confirmed that Fe3+ has a strong oxidation effect on S(IV). By maintaining the concentration of Fe3+ and dissolved oxygen in the liquid, we can get a stable desulphurization efficiency.
