研究结果表明:渤海湾COD季节之间变化不明显,5月、8月及10月的COD具有指数分布特征;COD年际间变化呈下降趋势,与同期COD排放变化趋势吻合;COD的污染风险概率符合Pareto型超阈值分布函数。
2.
By means of applying different levels of pig manure and cattle manure to potted ryegrass,the paper studied the capacity of absorbing organic manure of ryegrass and secondary pollution risk by determining the amount of the nitrogen and phosphorus absorbed by ryegrass,and residue in soils and losses.
对盆栽黑麦草施以不同水平的猪粪和牛粪两种有机肥料,通过测定黑麦草对氮和磷的吸收量、土壤的残留量及粪肥中氮和磷的损失量,研究了黑麦草对养殖场粪肥的消纳吸收能力及可能产生的二次污染风险。

补充资料:污染
分子式:
CAS号:
性质:现今绝大多数发酵过程为纯种培养过程,即在培养过程中只允许一种微生物生长,若有其他种微生物窜入培养液中生长则叫污染,也叫染菌。发酵过程被杂菌污染后,由于杂菌生长会与生产菌种争夺营养和溶氧,杂菌所分泌的代谢物不但会影响目标产物的纯度还可能降低或升高pH值,还可能对生产菌种起抑制作用,大大干扰生产菌的生长,甚至使生产菌死亡,对发酵造成极大的危害。
