The rapid industrial development and population growth increase the utilization of fresh water resulting in an increase of the amount of wastewater. Several Countries face a double challenge with regard to water resources, namely meeting the growing need for water for the population and treating the wastewater generated for application. The toxicity found in these water streams threatens the environment and human health. Hence the urgent need is to treat wastewater. The DRC is not immune from this threat. Its average population growth rate has exceeded the 3% and the number of industries it hosts continues to increase. The wastewater generated by this increasing pressure from urbanization and industrialization must be treated as required in the Congolese legal arsenal. Various factors need to be considered prior choosing the water treatment method. The choice must take into account the imperatives of the moment which are: modernization (local context) and sustainable development (international context). There are several wastewater treatments that are widely used for the removal of toxic elements such as ion exchange, reverse osmosis, chemical precipitation and electro-coagulation just to name a few. The most recent studies have shown that the galvanic technique can be used in the purification of water from domestic and industrial origin to meet drinking water standards. Various researchers have used this technique at laboratory and pilot scale demonstrating its cost-effectiveness as it uses no chemical reagents, consumes less energy and occupies only a small space for processing large flows. However, there are very few studies demonstrating the success of this treatment on an industrial scale. Therefore, this work seeks to understand and master the mechanisms that take place in the galvanic treatment. In addition, this study focuses on the development of a robust prototype that is adaptable to the needs of various users while at the same time being relatively cheap

海水淡化副产浓海水的排放会对海洋生态环境产生不利影响乃至破坏,但其与河水间存在的盐差能可被利用,是一种可再生能源。反电渗析是可以有效将盐差能转化为电能的新型绿色发电技术。以浓海水和河水分别作为反电渗析的浓、淡室进料溶液,基于国产亚德世膜,采用不同的隔板考察了膜间距离和流道类型对反电渗析性能的影响,并用进口富士膜进行了实验对比。结果表明:随着膜间距离的增大,膜堆开路电压和内阻增大,功率密度和离子迁移量减小;相同膜间距离下,直流道隔板的产电性能优于斜流道;采用富士膜的产电性能和离子迁移量影响规律与亚德世膜一致。综合考虑开路电压、功率密度和离子迁移量,选用0.85 mm的直流道隔板较优,功率密度为0.363 2 W/m~2。该研究为浓海水的科学利用提供了参考借鉴。

The study focuses on the assessment of the surface water quality of the mining city of kakanda (Lualaba Province in the DRC) to highlight pollution from mining activity. In addition to literature research, the identification of mining activities and the location of rivers and streams, the methodology adopted consisted in analyzing the water upstream and downstream of different discharge points of final effluents. The choice of parameters was made according to the Congolese legislation on this subject. Field observations indicated that liquid effluents from mining plants are discharged into the natural environment through drains. Chemical analyses have shown that the waters of these drains are loaded with metals at concentrations tens of times higher than standards. The results of the physicochemical analyses also indicated a deterioration of the quality of the water downstream of the discharge points. The level of suspended solids reaches 182 mg/l for an acceptable level of 80 mg/l. The concentration of cobalt and manganese in the streams receiving the final effluents reaches, respectively, 0.659 mg/l and 1.709 mg/l for an acceptable threshold of 0.5 mg/l. The electrical conductivity, the chemical composition as well as the other parameters exploited have revealed pollution of mining origin.

The rotational structure of the C 2 molecule Swan (d 3 Π g←a 3 Π u) system (0,1) band has been recorded by optical heterodyne magnetic rotation enhanced concentration modulation laser spectroscopy in the range of 17730～17880 cm -1 . The C 2 molecule is generated by an electric discharge through a mixture of acetylene and argon gas and a well resolved spectrum is recorded with an absolute accuracy of 0.007 cm -1 . Sensitivity of the method enables us to observe not only the traditionally observed branches of Δ Ω =0 sub bands but also some Δ Ω ≠0 transitions, providing a slight improvement in the accuracy of some molecular constants of the two states. The theoretical spectra are simulated using the effective Hamiltonian of Brown and Merer and directly fitted to observed spectra; rotational parameters are derived from this fit for the two 3Π states.
