1) animal waste
畜禽场废弃物
1.
Two pilot composting experiments were carried out to investigate some parameters about the variation of metabolic enzymes and the degradation of phytotoxicity materials in the aerobic composting of animal waste,such as the composting temperature,the pH value,the germination index,as well as the activities of urease,cellulase,phosphatase and β-glucosidase.
通过2个堆肥试验,监测堆肥温度,测试pH值、种子发芽指数以及脲酶、纤维素酶、磷酸酶和β-葡糖苷酶活性等指标,探讨了畜禽场废弃物好氧堆肥的代谢酶变化特征和生物毒性物质的降解规律。

饮扣Zhua叩feiqiwlJ huishou eh以i包装废弃物回收处理(I’eclaim for waste Packa-罗materials)包装物用后处里或再生利用的活动。它是解决世界性环境污染的重要课题。按包装材料的材质分类,包装废弃物一般可分为纸质、塑料、玻璃、金属4大类。包装废弃物回收处理的分类如下:①纸包装废弃物回收处理。将废纸或纸板用于再造纸,将废纸或纸板通过制浆、除杂、模塑成型、干燥等工艺制成各种形状、尺寸的纸浆模塑包装制品。②塑料包装废弃物回收处理。卫生城埋—由于此法没有从根本上减少环境污染,相反给子孙后代留下污染源,因此不可取。焚烧—此法可使废弃物体积、重量大为减少,且可回收热能,但焚烧过程造成的重金属、多核芳烃、二氧化碳等物质会对空气、土壤产生二次污染。热解—塑料包装废弃物经热解处理可得到化工原料、燃料油和可嫩性气体,如中国科研人员发明用废塑料回收生产ABS树脂及废聚苯乙烯裂解还原为苯乙烯单体的技术。再生利用—如软质聚抓乙烯经过挑选、清洗、晾干后粉碎,再加人适量助剂重新塑化造粒成型,加人新料中使用。以废治废—如废聚氨醋泡沫塑料经简单机械处理后在一定条件下可有效吸附废水中的苯胺、苯酸及乳化油。③玻璃包装废弃物回收处理。包括旧玻璃瓶罐回收复用;碎下脚料重熔再制瓶罐。采用玻璃上色新技术,使玻璃表面的有色涂料遇热后消失变成原有无色透明玻璃,省却有色玻璃分拣工作。采用薄壁轻瓶技术使玻璃瓶雄轻量化,从减少废弃玻璃数量角度处理玻璃包装废弃物。④金属包装废弃物回收处理。金属包装废弃物的主要代表是铝质易拉雄(俗称二片罐),主要回收方法为铝罐重熔。与从铝钒土冶炼铝材相比,该法可节约大量能源和冶炼用配料并减少排放氟化铝造成的大气污染。 (陆关新)
