This International Standard specifies the requirements for solid-wall polyethylene (PE) pipes and fittings for soil and waste discharge (low and high temperature) inside buildings, as well as the system itself. It does not include buried pipework. It also specifies the test parameters for the test methods referred to in this International Standard. This International Standard is applicable to PE pipes and fittings, as well as assemblies of such pipes and fittings, intended to be used for the following purposes: a) soil and waste discharge pipework for the conveyance of domestic waste waters (low and high temperature); b) ventilation pipework associated with a); c) rainwater pipework inside the building. It is applicable to pipes and fittings designed for jointing by means of elastomeric sealing rings or by butt fusion or electrofusion.
上述六种处理技术中,卫生填埋技术一般作为其它技术的配套最终处理手段,很少单独使用。高温焚烧法适用于各类医疗废物,焚烧后废物体积和重量明显减少,消毒灭菌及污染物去除效果好,且技术成熟;但建设和运行成本很高,会产生二噁英等剧毒物质及其它有害气体。高压蒸汽灭菌法投资低、操作费用低、残留物危险性较低;但易产生恶臭、可能有空气污染排放,并且必须对医疗废物进行破碎处理至小于50mm的尺寸。...
地源热泵技术原理:地源热泵是一种利用地下浅层地热资源既能供热又能制冷的节能环保型空调系统。地源热泵通过输入少量的高品位能源(电能),即可实现能量从低温热源向高温热源的转移。在冬季,把土壤中的热量“取”出来,提高温度后供给室内用于采暖;在夏季,把室内的热量“取”出来释放到土壤中去,并且常年能保证地下温度的均衡。...
4.2.3.1热脱附技术适用于处置挥发性、半挥发性及部分难挥发性有机类固态或半固态危险废物,可用于处理含有上述危险废物的土壤、泥浆、沉淀物、滤饼等。 4.2.3.2熔融技术适用于处置危险废物焚烧处置残渣和固体废物焚烧处置产生的飞灰等。 ...
推广15医疗废物高温蒸汽处理技术将装入灭菌小车的医疗废物在高温蒸汽处理锅进行灭菌处理,处理锅内的废气经冷却、除臭、过滤后达标排放,处理锅内的废液经污水处理单元处理后用于工艺循环冷却水或用于运输车辆、装载容器清洗,灭菌后废物送入破碎单元毁形。也可先将医疗废物破碎毁形,再高温蒸汽灭菌。处理后医疗废物送往填埋场填埋。灭菌温度不低于134℃,压力不小于0.22MPa,灭菌时间不少于45min。...
