How much real cost has China paid for its economic growth?

China’s economic growth has a serious impact on the environment and resources. How much real cost did China pay for its economic growth? This paper estimates the monetary costs of resource depletion, environmental pollution, and ecological degradation. The paper examines the geographic distribution of resource and environmental losses across 31 provinces. The findings allow us to reach the following conclusions. First, the national cost of resource depletion, environmental pollution, and ecological degradation in 2005 was 2.5 trillion RMB. It accounted for 13.5% of China’s gross domestic product (GDP). Secondly, the cost of resource depletion, ecological degradation, and environmental pollution has a different spatial distribution. The cost of resources depletion mainly distributes in the central area, the cost of environmental pollution is in the eastern area, and the cost of ecological degradation lies in the western area. Thirdly, the cost of natural resources depletion is 1,672.5 billion RMB, accounting for 67.8% of the total cost of resource and environment. It indicates that economic development has a high cost of resource depletion.

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.

非水相硝基苯在含水层中的迁移释放规律

通过室内模拟实验,探讨了在非水相硝基苯污染含水层的条件下,其在含水层中的迁移及释放规律。迁移规律表明,非水相硝基苯并非在含水层中直接进行垂向迁移,而是一方面在自身重力作用下向含水层下部迁移,另一方面在地下水流的作用下随地下水同向运移,整体表现为随地下水流的侧向运移,并最终迁移至含水层底部。释放规律表明,非水相硝基苯在含水层迁移的过程中会向地下水大量释放,释放出的硝基苯在水流的作用下随地下水同向运移,污染源及迁移至含水层底部的非水相硝基苯均存在再次释放。
