The subject in this paper is the surface water of Yuecheng Reservoir in Handan. On the premise of analysing variation characteristics of sulphate of Yuecheng Reservoir, we recognized reasons of increased sulphate concentration value resulting in water pollution. It drew conclusions that sulphate concentration in Yuecheng Reservoir varied significantly during winter and reached maximum. At the same time, there was a significant correlation between sulphate concentration of atmospheric precipitation in urban areas and sulphate concentration of Yuecheng Reservoir, which was because that the sulphate of atmospheric precipitation reached to the reservoir by surface runoff, having a certain degree of influence on the sulphate concentration of Yuecheng Reservoir.Keywords

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

As a new type of high performance adsorbents and catalysts, activated carbon fibre (ACF) shows broad application prospects in flue gas desulfurization because of its unique physical and chemical properties. We designed a set of experiments to study the factors affecting desulfurization performance of ACF, namely determining desulfurization performance of ACF before and after its regeneration, ACF soaked with 100g lime and ACF soaked with the fly ash and lime whose ratio was 1:1. The results show that after ACF regeneration, desulfurization performance of ACF declines, and the duration is also reduced; after being soaked with 100g lime, desulfurization performance of ACF has been improved significantly, and the duration also increases; after being soaked with the fly ash and lime in the ratio of 1:1, desulfurization performance of ACF is higher than that soaked with 100g lime, and the duration is longer.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

The comprehensive evaluation of the monitoring data of surface water in Handan City, based on the model of fuzzy comprehensive evaluation, was made in this paper. According to the monitoring data, selecting seven evaluation factors, namely, permanganate index, BOD, total nitrogen, total phosphorus, ammonia, fluoride and dissolved oxygen, weight matrix has been established for each factor, and the weight of each factor was obtained in the assessment of water quality. Then using the membership function in fuzzy mathematics, computed the data measured, and obtained the corresponding water level. The result of the evaluation shows that the water quality of Handan city is V level, severely polluted, and it becomes a security risk to the residents' drinking water. Besides, it can be used as the scientific basis for water quality control.Keywords

The removal of hydrogen sulphide by using the activated carbon method is introduced in this paper. The desulphurization efficiency of desulphurizer is researched for different kinds of activated carbon under laboratory conditions. It focuses on the research of the removal efficiency of hydrogen sulphide by granular activated carbon, renewable granular activated carbon, granular activated carbon containing manganese dioxide and powdered activated carbon. The best type of activated carbon removing hydrogen sulphide has been obtained on this basis. The results of the studies show that the processing efficiency of granular activated carbon is far better than that of regeneration. The more the number of regeneration, the worse the desulphurization efficiency. The best activated carbon of desulphurization efficiency is the powdered activated carbon in the experiment. After the addition of manganese dioxide in granular activated carbon, the desulphurization efficiency could not be improved. It is clear that manganese dioxide does not play any role.Keywords
