秦巴山区降雨侵蚀力时空变化特征

降雨侵蚀力时空变化特征的研究对区域土壤侵蚀风险评估及水土保持规划具有重要的意义。利用秦巴山区及周边地区共63个气象站1961~2016年的逐日降雨量数据计算各站的降雨侵蚀力，借助Kriging空间插值法、Mann-Kendall趋势检验、Pettitt突变检验等方法分析了秦巴山区降雨侵蚀力的时空变化特征。结果表明：秦巴山区年均降雨侵蚀力为3 696 MJ·mm/(hm²·h·a)，年内变化呈单峰型，7月最大，占全年的26.6%；四季中，夏季最大，冬季最小。代际间，20世纪80年代的降雨侵蚀力最大，90年代最小。年际间，年降雨侵蚀力存在明显的阶段性，但未表现出显著的趋势性和突变性特征。秦巴山区多年平均降雨侵蚀力呈南高北低的分布格局，不同地区年均降雨侵蚀力变化于787~8 858 MJ·mm/(hm²·h·a)之间；整体而言，年降雨侵蚀力随纬度增加而减小，随海拔升高而减小。

Combination with catalyzed Fe(0)-carbon microelectrolysis and activated carbon adsorption for advanced reclaimed water treatment: simultaneous nitrate and biorefractory organics removal

A process combining catalyzed Fe(0)-carbon microelectrolysis (IC-ME) with activated carbon (AC) adsorption was developed for advanced reclaimed water treatment. Simultaneous nitrate reduction and chemical oxygen demand (COD) removal were achieved, and the effects of composite catalyst (CC) addition, AC addition, and initial pH were investigated. The reaction kinetics and reaction mechanisms were calculated and analyzed. The results showed that CC addition could enhance the reduction rate of nitrate and effectively inhibit the production of ammonia. Moreover, AC addition increased the adsorption capacity of biorefractory organic compounds (BROs) and enhanced the degradation of BRO. The reduction of NO₃^?–N at different pH values was consistently greater than 96.9%, and NH₄⁺–N was suppressed by high pH. The presence of CC ensured the reaction rate of IC-ME at high pH. The reaction kinetics orders and constants were calculated. Catalyzed iron scrap (IS)-AC showed much better nitrate reduction and BRO degradation performances than IS-AC and AC. The IC-ME showed great potential for application to nitrate and BRO reduction in reclaimed water.
