Oil fume was biodegraded in biofilter with green roof engineering as biological packing. The results showed that with biofilter culture forming biofilm for 10 days, inlet temperature at about 33 °C, residence time longer than 25s, relative humidity 85 %, VOCs concentration 1.0 mg·L−1, flow rate 3.35 m3·h−1, biodegradation efficiency of VOCs in oil fume reached over 90%, removal loading limit 0.30 g·(L·h)−1 while ΔP of biological packing kept below 2960 mmH2O·m−1.

This paper indicates that there are some shortcomings in the traditional sound pressure method for sound insulation measurement, such as sound leakage, flanking transmission and the low signal-noise-ratio. And then the impulse and sound intensity measuring methods are introduced. The progress of the sound intensity methods is also illustrated. In combination with environmental quality for noise in the national evaluation standard for green building, the prospect of applying the sound intensity method for sound insulation measuring on green buildings is presented.

As the energy supply lack and climate deterioration, carbon emissions problem is more and more concerned by the world. For construction industry, its related products consume large amount of energy and lead to heavy carbon emissions. In order to provide a rule in evaluating low-carbon performance of buildings, an evaluation frame is given from both life-cycle and low carbon of buildings, and detailed indexes are designed for reflecting entirely building performance including energy, environment, function, economy and specification.

Swelling force is one of the most important parameters of study on swelling rock and soil. The factors in influencing swelling force: initial water absorption, dry density and time effect, are further researched. Swelling force increases with dry density, but decreases with increasing initial water absorption, which are both expressed by exponential function. The relationship between swelling force and time is described by piecewise exponential function. The computing formula of swelling force is established, taking initial water absorption, dry density and test time effect as independent variables. The study lays a theoretical foundation for the research on shear strength of swelling rock and soil.

Effective coagulation for low-turbidity, micro-pollution source water has long been a technical challenge in safe drinking water supply. This paper investigated the enhanced coagulation for typical low-turbidity, micro-pollution reservoir water (turbidity of 1.3 NTU, COD of 4 mg/L). The methods included coagulant comparison, dose optimization for coagulant aid, addition of Gaolin, and sludge recycle. The effluent turbidity, COD, and UV254 were monitored. The results show that the best coagulant was PAC with an optimal dose of 30 mg/L. PAM was a very effective coagulant aid and improved 25% turbidity reduction at a dose of 0.6 mg/L. Considering the cost, we proposed 0.05 mg/L PAM together with 20 mg/L PAC, and the total cost would be 0.031 RMB/t. Gaolin did not help coagulation for this type of source water. Sludge recycle was the most economic method and could reduce the coagulant dose to 5 mg/L. The best turbidity range for the mixture was 15–35 NTU.

Silt soil in estuarine, creek, lake and coastal area is formed by slurry suspension particles' sedimentation and consolidation. For the still environment, great amount of silt soil lead to serious depositions. In order to analysis the mechanisms of silt soil sediment and consolidation, settlement column experiment is adopted to simulate the sedimentation and consolidation process. According to the experiment result, three settlement stages can be defined through the characteristics of settlement curves, which are free sediment stage, logarithmic linear attenuation settlement and consolidation settlement. And an observation is that relationships between soil properties (e.g. initial concentration, clay content and organic content) and settlement process parameters can be determined. Consolidation coefficient cv as process variable is given based on Terzaghi consolidation theory and settlement column experiment. Sedimentation research achievements show great significances to the regulation and dredging project of Shenzhen River and Bay.
