对浏阳市永安镇某养殖场养殖粪便中Cu2+、Zn2+、Cd2+、Pb2+等重金属离子的含量进行了分析,并以石墨板为阳极、不锈钢板为阴极的电化学方法对养殖粪便进行处理,考察了电解电压、电解时间等因素,对样品不同区域pH值以及Cu2+、Zn2+、Cd2+、Pb2+等重金属离子处理效果的影响,同时计算能源消耗费用。结果表明:阳极区域的pH值呈下降的趋势,阴极区域的p H值呈上升的趋势,且反应稳定后阴极和阳极区域的pH值之和等于14;在反应器中的不同区域内,各重金属离子的去除效果均不同,阳极区域的去除效果最佳;在样品初始浓度为90 g/L、pH 6.82的条件下,当电压为40 V,电解时间为4 h时,对养殖粪便的处理效果与费用最佳...

The heavy metals such as Cu2+, Zn2+, Cd2+ and Pb2+ in the livestock manure from one farm in Yong’an Town, Liuyang City were treated with the electrochemical method of graphite as anode and stainless steel plate as cathode. The effects of electrolytic voltage and electrolytic time on pH value and heavy metals(Cu2+,Zn2+, Cd2+ and Pb2+) of livestock manure were studied. Moreover, the cost of energy consumption for removal heavy metals from livestock manure was calculated. The results showed that the pH value of manure in the anode region decrease...
