中文摘要: |
选择典型规模化猪场,对猪场水井水质进行动态分析和监测。结果显示,猪场5 个水井水体pH
值、总氮浓度和粪大肠菌群数量分别为7.72~7.79、1.73~2.87 mg/L、3.663×105~5.257×105 个/L,5 个水井粪大
肠菌群超标现象较为严重。两个典型水井的水质分析显示,硝酸盐氮和悬浮物均符合地下水Ⅰ类水标准,亚
硝酸盐氮含量均符合地下水Ⅲ类水标准。井水总氮和总磷含量分别为3.06~3.42 mg/L 和0.12~0.21 mg/L。井水
CODCr 和BOD5 测定值变化表明井水含有一定浓度的有机污染物。氨氮和粪大肠菌群均处于严重超标状态。总
体上,猪场地下水水质状况堪忧,主要污染物为氨氮和粪大肠菌群。 |
英文摘要: |
A typical large-scaled pig farm was selected to monitor the ground water quality. The results showed
that pH,total nitrogen concentration and number of fecal coliforms was 7.72-7.79,1.73-2.87 mg/L and 3.663×
105-5.257×105,respectively,in the water of five wells,the number of fecal coliforms exceeded the standard level of
ground water. Further investigations in well water quality were conducted on two typical wells. Results showed that the
concentrations of nitrate nitrogen and total soluble solids were lower than class Ⅰ of water quality standard;the nitrite
content was lower than class Ⅲ of water quality standard. The concentrations of total nitrogen and total phosphorus
were 3.06-3.42 mg/L and 0.12-0.21 mg/L,respectively. The well water was polluted by some organic contaminants as
evinced by the variations of COD and BOD5. Ammonia nitrogen and fecal coliforms were pollutants found in the water
of two wells and were much higher than the class V of water quality standard. In summary,the water quality in this
large-scaled pig farm was poor mainly because of the ammonium nitrogen and fecal coliforms contamination |
