The removal of hydrogen sulphide by using the method of dry desulphurization in a normal temperature iron oxide is introduced in this paper. The experiment has been conducted by using the ferric oxide as the desulphurizer in the waste red mud and added wood chips and calcium oxide for the removal of hydrogen sulphide. Also, the desulphurization efficiency of desulphurizer is researched in different drying temperatures and different ratio conditions, and the best condition of removing hydrogen sulphide is studied. The results of the studies show that the best conditions of removing hydrogen sulphide are 80% of red mud, 5% of wood chips and 15% of calcium oxide at 110°C drying temperature; 85% of red mud, 5% of wood chips and 10% of calcium oxide at 130°C drying temperature; and 70% of red mud, 5% of wood chips and 25% of calcium oxide at 150°C drying temperature. In three different drying temperatures, the best ratio is 85% of red mud, 5% of wood chips, 10% of calcium oxide, and the best drying temperature is 130°C. This test also provides technical support for further industrial utilization.Keywords

With the increase of traffic mileages, traffic flow and running speed, highway traffic noise pollution is aggravating and expanding the interference degree and scope of residents along the line, whose normal life, work, study and rest environment are disturbed seriously. Traffic noise pollution has gradually become the most concerned environmental pollution problem for the residents who live along the line. We monitored the noise of the section of College North Road which is from Hebei University of Engineering North Gate to Meishilin Supermarket. Through comprehensive analysis and evaluation on social environment and residents' health impact, we proposed reasonable measures to reduce noise pollution.Keywords
