SBR法运行控制工艺研究进展

SBR法是一种具有独特的优点的废水生物处理工艺，但至今还没有一套公认的运行控制工艺，本文从SBR法的启动，充水时间及反应时间的确定，模糊控制，目标控制操作等几方面对SBR工艺的运行控制做了评述，并对其今后的研究方向做了展望。     

Carbon mitigation potential and costs of forestry options in Brazil,China, India,Indonesia, Mexico,the Philippines and Tanzania

This paper summarizes studies of carbon (C) mitigation potential and costs of about 40 forestry options in seven developing countries. Each study uses the same methodological approach – Comprehensive Mitigation Assessment Process (COMAP) – to estimate the above parameters between 2000 and 2030. The approach requires the projection of baseline and mitigation land-use scenarios. Coupled with data on a per ha basis on C sequestration or avoidance, and costs and benefits, it allows the estimation of monetary benefit per Mg C, and the total costs and carbon potential. The results show that about half (3.0 Pg C) the cumulative mitigation potential of 6.2 Petagram (Pg) C between 2000 and 2030 in the seven countries (about 200× 10⁶ Mg C yr^-1) could be achieved at a negative cost and the remainder at costs ranging up to $100 Mg C^-1. About 5 Pg C could be achieved, at a cost less than $20 per Mg C. Negative cost potential indicates that non-carbon revenue is sufficient to offset direct costs of these options. The achievable potential is likely to be smaller, however, due to market, institutional, and sociocultural barriers that can delay or prevent the implementation of the analyzed options.     

焚烧废气处理试验研究

介绍了有毒有害焚烧废气处理的原理及工艺流程,分析了焚烧废气中粉尘、HCl和NOx去除的原理,根据焚烧废气处理的试验结果,探讨了影响处理效果的因素.试验表明,在试验条件下,焚烧废气中的粉尘、NOx、HCl在吸收塔均达到较高的去除效率,其中粉尘的去除效率92%;NOx的去除效率平均58%,高的可达80%;HCl的去除效率平均达87%.随着液气比增大,其各种污染物的去除效率有所增加.
