Adsorption of heavy metals ion by microorganisms is emergying technology to treat wastewater. In this study, the cadmium-resistant Pseudomonas aeruginosa E1 was investigated in absorption of cadmium ion from solution. The effects of polluted solution intial pH, biosorption time, and cadmium ion concentration and biosorbent amount on biosorption efficiency were investigated. The cadmium removal percent was used to reflect the efficiency of biosorption. From the views of production and application, the biosorption conditions were discussed. Moreover, the absorbent after absorption was analysized by Fourier transform infrared spectroscopy. The result suggested that the biosorption of cadmium involves C=O, C-O, O-H, C-N, N-H groups and phosphate functional groups.

It is very difficult to calculate the inlet air volume and the outlet smoke volume under natural ventilation in a very low flow speed through the same opening. The way that the smoke yields and transportation is analyzed on the basis of the burning state reflected by the parameter ¿ in the compartment of fire origin is easy to extend to the real building without the certain limitation of the building structure such as the opening height and the geometry prototype. The ratio ¿ is obtained through temperature measuring in this paper with the continuous adjustment of the neutral plane by iteration.

Temperature of urban sewage is suitable, but its flux is insufficient as cooling and heating source. So in many cases the conventional sewage source heat pump system is unable to satisfy the building heat peak load. According to this condition, a novel mentality is proposed about which the freezing latent heat of urban sewage is used as the low temperature heat source of heat pump in the building as well as sensible heat. Then the important equipment is developed, freezing latent heat exchanger namely, which can eliminate the ice safely, extract the heat continuously, remove the sewage soft-dirt, and strengthen heat transfer. According to the sewage characteristics, reasonable form of the urban sewage source heat pump with freezing latent heat collection is discussed and established. The results of analysis show that the new system has broad feasibility and giant application potential.

Numerical simulation was carried out on the High Temperature Air Combustion of coal gas in an industrial furnace with a multi-jet burner. The furnace was a rectangular chamber of 800mm×800mm× 1400mm. A circular fuel jet of a diameter of 10mm is at the center of the wall. 5 circular air jets equably distributed around the fuel jet with different straddle angles. A PDF (Probability Density Function) combustion model based on a b function was selected to simulate the gas combustion combined with the standard k-e model. The radiation was simulated by a Discrete Ordinates method. The NOx emission was simulated by thermal NOx model. The effect of the distance between the fuel and air jets on the combustion characteristics was discussed in this paper. The results showed that there was the recirculation zone in the furnace due to the interaction of the jets. The recirculation of the flue-gas changed the local distribution of the fuel and oxygen in the furnace and then influenced the local NOx generation. When the distance between the air and fuel jets increased, the mixing of the fuel and air could be effectively delayed and an obvious recirculation zone appeared between the air jets and fuel jet that reduced the local oxygen concentration. More fuel would be burnt in the low oxygen region and combustion zone and the flame volume were both increased which made the temperature distribution became more equable and local high temperature was suppressed. When the dimensionless distance between the air and fuel jets was 2.5, a minimum NOx emission of 45 ppm was achieved at 15% O2

Agricultural waste disposal is becoming a problem due to its increasing production and potential pollution. As a kind of biomass, agricultural waste can be used as a sustainable and renewable source of energy. Agricultural waste disposal is of great economic and environmental importance. In the paper, the effect of the mineral matters in agriculture waste on the reactivity of its char was investigated. The oxidation behavior of the resultant char depends strongly on the agriculture waste type. The oxidation behavior of AW 1 and AW 2 char differs greatly from each other because of the difference in their mineral matters. The pretreatment with dilute acid solution in the sequence of HCl and HF acid can remove nearly all the inorganic constituents from the agriculture waste. The mineral removal results in a decrease in the reactivity of the resultant char.
