Abstract : the generation and control of odorous gases in treating night soil sludge was exploited in this paper . the results indicated that high concentration odorous gases can be generated during whole process in treating night soil sludge . in order to control the secondary pollution of odorous gases , the authors put forward a new kind of deodorization process - combustion in methane boiler and absorbde in washer 文摘:对粪渣污泥处理处置过程中恶臭气体的产生及控制进行了研究,结果表明,在综合处理全过程的几个主要阶段都会产生高浓度的恶臭气体,为防止恶臭气体对环境造成的二次污染,提出采用沼气锅炉焚烧和洗涤塔相结合的除臭工艺,洗涤塔除臭只有在系统启动、调试和沼气锅炉发生故障的情况下使用。
Article 34 the burning of asphalt , asphalt felt , rubber , plastics , leather and other materials that may produce toxic or harmful smoke or dust or malodorous gases in densely inhabited areas shall be prohibited ; when , under special circumstances , such burning is really necessary , it must be reported to the local environmental protection department for approval 第三十四条禁止在人口集中地区焚烧沥青、油毡、橡胶、塑料、皮革以及其他产生有毒有害烟尘和恶臭气体的物质;特殊情况下确需焚烧的,须报当地环境保护部门批准。
