在4 L反应器中,以补加葡萄糖和硫酸铵的猪场废水为基质,不接种活性污泥,加入粉末状活性炭对废水土著微生物进行预固定.通过批次进水并控制运行条件(逐渐提高COD、NH 4+-N负荷、缩短沉降时间、提高曝气量)培养同时脱氮除碳好氧颗粒污泥,研究了该好氧颗粒污泥的脱氮除碳功能及对高碳氮负荷冲击的响应.结果表明,成熟好氧颗粒污泥为土黄色不规则球状,粒径为0.5~3.5 mm.COD和NH 4+-N负荷分别在4.80~12.6 kg.(m3.d)-1和0.217~0.503 kg.(m3.d)-1时 ...

重金属污染水体的修复是一项艰巨的工程,以往的物理及化学修复不仅投资巨大而且效果不甚理想,而利用水生植物修复重金属污染水体是一种低廉有效的处理方法。文章综述了利用大型水生植物植物修复重金属水体的研究进展,重点阐述了4种生活型水生植物(挺水、漂浮、浮叶和沉水)对重金属的蓄积效果;并对植物修复重金属污染水体的影响因素如植物生活型、生物量、株龄以及重金属的类型、初始浓度和水体的理化性质等进行了讨论。最后,对利用组织培养技术进行植物筛选、利用基因工程技术使水生植物对重金属具有超蓄积能力 ...

Simplified activated sludge model in sewage treatment process
本发明涉及一种简化的污水处理过程活性污泥模型,步骤为:对现有模型进行简化:结合我国污水处理厂的实际情况,对活性污泥1号数学模型ASM1模型进行组分和过程简化,只考虑COD组分组分和碳的氧化过程,对简化后的模型进行数据转换:在污水处理厂的入水口,建立将常规水质分析指标转化为模型组分浓度的转换模型;在污水处理厂的出水口,建立将通过模型计算得到的出水组分浓度转化为常规水质分析指标的转换模型;模型修正:根据水温变化的幅度将一年分为四个阶段,根据Arrhenius公式对模型参数校正 ...
