摘要：
After the pretreatment, Bamboo Charcoal (BC) were chemically modified with succinic acid. Then explore the characters of Modified Bamboo Charcoal (EBC) and the adsorption of BC for Cd(II). Fourier Transform Infrared Spectroscopy(FTIR) and Scanning Electron Microscope(SEM) were applied to analyze the material microstructure and its chemical bond of the adsorbent. The static test shows that effects of reaction time and pH value on the adsorption of BC for Cd(II). The adsorption process are found to be well described by the pseudo-second order adsorption kinetics. Besides, the maximum adsorption mounts of BC after modification calculated from pseudo-second order adsorption kinetics raised from 6.05 to 10.94 mg . g(-1).
摘要：
The effect of masss of natural diatomite, initial dye concentrations, pH and temperature on adsorption was investigated. The adsorption of reactive dye was slightly increased then decreased with rising amouts of natural diatomite that is increasing competition of natural diatomite. The removal rate of reactive black increase with the temperature because of endothermic reaction. The removal rates of reactive black from solution were decreased as the pH increase and gain the maximum in low pH. The removal rate for all concentrations were rapid at initial stages and then keep increase gradually until the progress until equilibrium reached.

摘要：
Based on the particularity of the water supply and sewerage design of dining hall’s construction and retrofit in the college, some problems in design, such as water-supply system, drainage system, hot water system, and reclaimed water system are discussed. Also some corresponding advices and solutions are put forward. Some explorations, especially in the canteen hot water supply and the thermal insulation are made. In this way, the designs can better meet the requirements of operation.

摘要：
The application of main radionuclide in the department of nuclear medicine in a large-scale Hospital are introduced; Radiation levels of γ-rays and β-ray in all the workplace are monitored. It has been found that the highest γ-ray radiation level is in the Leaching-packing room, and the highest β-ray radiation level is in the temporary waste storage box. Possible impacts of main radionuclide on public and the staff are evaluated and according to the actual situation, the controlling measures of reducing the pollution are expounded, finally, the major evaluation conclusions are given and several suggestions about solving the pollution are proposed.
摘要：
The adsorption capability of diatomite to reactive dyes (reactive black K-RB and reactive golden yellow X-G) in aqueous solution was studied, and adsorption mechanism was explored from the view point of kinetics. The results show that the equilibrium adsorption capacity (q(e)) of each dye increases with the temperature. On the same condition, the q(e) of reactive black is more than reactive golden yellow. The adsorption processes follow the pseudo second-order model, and the structure, size and functional groups of dyes are important factors to adsorption reaction. The dye adsorption isotherms fit well to Freundlich and Langmuir equation. The Freundlich equation 1/n between 0.3585 and 0.4411 indicates favorable adsorption. The adsorption activation energy of reactive black K-RB and reactive golden yellow X-G are 12.373 kJ/mol and 25.913 kJ/mol, respectively, which indicates that it belongs to physics adsorption. The main driving forces of adsorption are electrostatic attraction and van der waals force.
