Feasibility of extracting water from air on ship¡¯senvironment was evaluated on a general cargo ship navigating between Dalian and Hamburg at May. Firstly, analysis of the energy equilibrium among the heat evaluated from fuel consumption rate and that distributed to different parts of the main engine system was carried out, an experimental unit employing the waste heat of the cylinder jacket water was then set up on the afterdeck nearby central air conditioning room. Two adsorption towers with the same size and capacity were design in consideration of the heat and mass transfer characteristic of the water vapor within the adsorbent bed of the silica gel and that of the composite compounded with calcium chlorate. Daily amount of water produced from the extracting unit and that from desalination plant were compared in terms of the main indices prescribed by the National Standard for Drinking Water. Results show that the waste heat of the cylinder jacket cooling water under normal working condition is enough to meet the need of the heat powering the extracting unit, silica gel with pores larger than mesopore is a better adsorbent in marine environment, the composite has a better performance in water vapor adsorption, but performance in both silica gel and the composite will be weakened on board. Results also reveals that the indices of water from the extracting unit and the desalination plant are all within the permissible range prescribed by the national standard. Conclusions are drawn that the monolith of the adsorbent and the flexible connection should be used to dampen the influence from the vibration and bumping of the ship.

A pilot-scale experiment with a treating3capacity of 10 m per day was carried out for swine wastewater treatment by using of a moving bed biofilmreactor (MBBR). The reactor was start-up in 60 days period and run for a year, and an average removal rate of 82.9%for COD and 89.0% for ammonia were achieved, under a hydraulic retention time (HRT) of 12h, with influent COD and ammonia of 1686 ¡À 497 mg/L and 582 ¡À 126 mg/L, respectively. The effluent met the national discharge standard of pollutants for livestock and poultry breeding(GB 18596-2001) of China. The kinetics of organic carbon and ammonia removals in the MBBR was studied based on the Stover-Kin cannon model and the 1/2 order substrate removal model, respectively. Temperature coefficient "¦È"was introduced into the COD and ammonia removal models to describe the effects of the temperature. The model simulated results showed good agreements with experimental results. The model could be employed for the design of a full-scale MBBR process for simultaneous removal of organic carbon and ammonia from swine wastewaters.

According to our previous study, it is believed that ultra-filtration with polyether sulfone (PES) flat-sheet membrane is suitable for the concentration process of alkaline peroxide mechanical pulping (APMP) plant¡¯s effluent. So we scaled up the concentrating experiment to a pilot-scale. Specifically, the cross flow velocity and volume reduction factor were optimized again for a higher flux and a lower system energy consumption. A mathematical model was established to obtain the optimal parameters. An estimation of energy and water saving effect were also developed. The optimal ultra filtration conditions obtained were: molecular weight cut-off at 10,000 Dalton, trans-membrane pressure at 3 bar, feed temperature at 50¡æ, cross-flow velocity at2 m/s, and volume reduction factor at 0.9. The average permeate flux under these conditions was 43.21 l/m2.h. The total solids content was increased from 25.47 g/l in the feed to 128.36 g/l in the concentrate. The permeate had low total solids content of 11.03g/l, Chemical Oxygen Demand of 9180 mg/l, and Biochemical Oxygen Demand of 5870 mg/l. Such qualities would allow the permeate to be reused in the APMP process after lightly biochemical treatment. With this new concentration process, about6201.7 kWh energy can be saved and 22.5 m3 effluent discharge can be reduced for each ton of pulp produced.

The removal of reactive red 2 and methylene blue from aqueous solution was studied using soybean meal as an adsorbent. The effects of some parameters such as solution pH and contact time on the adsorption were investigated. The equilibrium time was found to be more than 60 min for equilibration. Equilibrium data conformed to the Freundlich, Langmuir and Redlich¨CPeterson isotherm models, where the maximum adsorption capacity of methylene blue was 50.2 mg g-1 for the Langmuir isotherm at 25 ¡æ, but the maximum adsorption capacity of reactive red 2 was low (16.4 mg g-1). Soybean meal, which are easily available and inexpensive, could be employed as a promising adsorbent for the removal of methylene blue, but not for reactive red 2.
