Mixing sewage sludge with coal fly ash could reduce the mobility of heavy metals in stabilized sewage sludge. In order to access the mobility and bioavailability of copper (Cu), zinc (Zn) and nickel (Ni) in stabilized sewage sludge, five-step sequential extraction method was performed according to the modified Tsessier method. The results showed that application of coal fly ash to sewage sludge increased the percentage of exchangeable Cu and Zn, but decreased the residual phases of Cu and Zn, indicating that mixed sewage sludge with coal fly ash may increase the mobility of Cu and Zn. However, compared with Cu and Zn, the effect of coal fly ash on the mobility of Ni in stabilized sewage sludge was inapparent. Moreover, the residual Ni accounted for 44.6 % to 56.3% of the total Ni in stabilized sewage sludge, indicating that land application of stabilized sewage sludge has the low Ni risk.

A preliminary study using gamma radiation on coking wastewater samples was carried out. Colority, Cyanide and Chloride content results were obtained at different doses (1.0, 3.0, 5.0 and 7.0 kGy). As increase of the absorbed doses, a decrease of colority and cyanide were observed after irradiation, whereas at the doses of 3 kGy, 5 kGy and 7 kGy, the cyanide were gradually increasing, the colority remain unchanged. The content variations of chloride with increasing absorbed doses were slowly increasing, which indicate irradiation of coking wastewater has no or little effect on the chloride content. The results obtained highlight the potential of this technology for coking wastewater treatment.

This research aimed to determine the organic and turbidity removal efficiencies of different coagulants to raw water with low temperature and turbidity. The experiments employed poly aluminum chloride (PAC), poly aluminum ferric chloride (PAFC), poly ferric chloride (PFC) and poly aluminum ferric chloride collosol (AFO) as coagulants to simulate the treatment processing. The results indicated that the optimum doses of selected coagulants were identified at 30mg/L for PAC, 25mg/L for PAFC, 30mg/L for PFC and 35mg/L for AFO by the experiments of impurities removal. Compared the impurities removal rates of low turbidity water, the PAC obtained the greater treatment efficiency.

The performance of modified polyvinylidene fluoride (PVDF) membrane in oilfield wastewater treatment was investigated Oil content, suspended solids (SS), turbidity and total organic carbon (TOC) of the stable effluents were analyzed. Moreover, the fouling mitigation was quantitatively evaluated from the view of filtration resistances. In addition, fouled membranes were washed by the chemical method and it was found that the flux recovery ratio of the modified membrane was higher. The experimental results indicated that the modification improved PVDF membrane flux and anti-fouling ability without sacrificing the performances in oilfield wastewater treatment.

The sawdust was employed as the matrix in a bio-composting reactor and the biological characteristics in terms of the abudanance of microbes, similarity and diversity of biocommunity and the efficiency of organic removal have been investigated in this study. It was found that in the first 30 days, the abudanance of aerobic microbes decreased from 8.09×108cfu/ to 9.27×107cfu/g, and then it maintained approximately 108cfu/g for 35 days, and at the end of the composting cycle, it decreased around 1.3×107cfu/g. Meanwhile, the amphimicrobe slightly increased from 2.75×105cfu/g to 1.81×106 cfu/g in the first 20 days and then it increased to 3.85×108cfu/g on day 40 with a relatively fast speed. From day 40, the abudanance of amphimicrobe was hardly changed. In the first 30 days, the BOD5 accumulated removal efficiency increased from 27% to 50%, and from day 30 to Day 60, it remained approximately 50%. In the later period of this study, i.e., from Day 60, the removal efficiency decreased to 40% as measured at the end of the composing cycle. Concerning on the degradation rate, it increased to 7 mg·g-1·d-1 on Day 30, and then it decreased to 1.4 mg·g-1·d-1 at the end of the cycle.

Observations at two tidal gages show that the M2 tide is dominant in the Quanzhou Bay. The cross section connecting two tidal gauges is tentatively taken as the lateral open boundary of the studied area and 10 tides are used to force the Princeton Ocean Model to simulate the tidal regime in the bay. A simple wetting and drying scheme and a river discharge model are also added to the POM to reproduce the alternative immersion and protrusion of the tidal flats on the flood and ebb, respectively, as well as the development of river plumes. Simulations show that the rectilinear currents dominate in the bay though the regions near the mouth of the bay are characterized by the rotary currents. In addition, based on the evolution of Jinjiang River plume, it can be suggested that the formation of the tidal flats may be due to the river-borne sediments, since the river-borne sand and clay settle down and accumulate in the downstream of the river plume.

The muddy estuary and coasts which are composed of cohesive sediment spread over the world and also take on widespread distribution in China, the cohesive sediment possess rheological Properties which is not presented by non-cohesive sediment. A laboratory study is present on rheological measurement of natural moods using NXS-11A viscometer. In order to make good understand of complicated viscoelastic characteristics at low shear rates, the dynamic rheological measurement is made using CVO rheometer to research rheological characteristics of cohesive sediment that represents the resistivity to flowing and distortion and variance in internal structure.
