Circulating cooling water consumes a large amount of water in thermal power plant, and there are some problems such as scaling and corrosion in the system. This study presents a novel circulating cooling water treatment process based on microbes. The mechanism and influencing factors of microbial treatment process of circulating cooling water is studied. Water from circulating cooling system of a 300 MW thermal power unit was used, dynamic simulation test was carried out and com- pared between the microbial treatment process and the traditional chemical treatment process. The results showed that nutrient solution dosage on calcium hardness is positive, while the interaction between nutrient solution dosage and aeration rate has negative effect. When ammonia concentration is 10–50 mg/L and aeration rate is 1–3 L, and the minimum calcium hardness is 18.3 mmol/L. Reducing the concentration of nutrient solution and increasing the aeration rate are beneficial to slow down the corrosion of carbon steel and stainless steel. When ammonia concentration is 10–50 mg/L and aeration rate is 1–3 L, the minimum corrosion rates are 0.01552 and 0.00110 mm/a, respectively. Compared with traditional chemical treatment process, the microbial treatment process can achieve the scale inhibition and corrosion inhibition target at high concentration ratio, the highest concentration ratio can reach 5.4, and the corrosion rate of carbon steel and stainless steel is low. The green, efficient and environment-friendly microbial treatment process provides a new method for circulating cooling water treatment, which can obtain stable and economical operation of circulating cooling water system under high concentration ratio.

The present study aimed to investigate the efficacy of activated carbon (AC) electrode embedded with naturally occurring metal oxides (MO) from rocks for antibacterial activities against both gram-negative ( Escherichia coli ) and gram-positive ( Salmonella aureus ) bacteria using capacitive deioniza-tion technique. The desalination and disinfection performance of the fabricated AC/MO electrode was evaluated through the batch mode experiments conducted at a potential difference of 1.2 V for 240 min (4 h). The results revealed that the AC/MO electrode achieved a complete removal efficiency of 100% for E. coli and 60% for S. aureus in the field water collected from Nduruma stream (natural water). The bacterial removal mechanism was attributed to the capacitive deion-ization (CDI) process and physical adsorption. The study highlights the potential of AC/MO electrode material as an effective antibacterial agent for the CDI process, which may have significant implications for the development of new technologies for water purification and disinfection.
本研究旨在利用电容去离子技术研究岩石天然金属氧化物(MO)包埋活性炭(AC)电极对革兰氏阴性(大肠杆菌)和革兰氏阳性(金黄色沙门氏菌)细菌的抑菌活性。通过在1.2 V电势差下进行240 min (4 h)的间歇模式实验，对制备的AC/MO电极的脱盐和消毒性能进行了评价。结果表明，AC/MO电极对Nduruma溪流(天然水)现场水的大肠杆菌和金黄色葡萄球菌的去除率分别达到100%和60%。细菌的去除机制归因于电容脱离子(CDI)过程和物理吸附。该研究突出了AC/MO电极材料作为CDI工艺有效抗菌剂的潜力，这可能对水净化和消毒新技术的开发具有重要意义。

, and change in surface morphology by scanning electron microscopy. The point of zero charges pH pzc of xanthate-modified P. vulgaris was observed to be 7.20 which makes it appropriate for the sorp- tion of cations. The batch sorption implementation of xanthate-modified P. vulgaris includes sorbent amount, pH, linear and non-linear regression analysis, and kinetic curves. The xanthate-modified P. vulgaris adsorbed 95.65% cadmium (at pH 4.0) and 90.36% of lead (at pH 5.0) from a single aqueous system. The sorption of Pb 2+ and Cd 2+ by xanthate-modified P. vulgaris follow the linear regression of Langmuir isotherm with q max of 160.97 and 150.50 mg/L, respectively which is substantially greater than that of many other reported ones. The xanthate-modified P. vulgaris demonstrated rapid uptake capacity of Pb 2+ and Cd 2+ following the high value of correlation coefficient with pseudo-second-order kinetics. This sorption process for Pb 2+ and Cd 2+ was found to be endothermic and spontaneous. The binding capacities however reduced in the binary system. This, therefore revealed that the xanthate-modified P. vulgaris can be an encouraging biosorbent for the remediation of Pb 2+ and Cd 2+ from contaminated water.
