| 摘 要： | 以实际养猪废水为对象,采用吸附-过滤法进行预处理,研究稻草滤料和稻草-沸石双层滤料在不同滤速下对养猪废水中CODCr、氨氮和磷的去除效果.结果表明,稻草-沸石双层滤料对CODCr、氨氮和磷的去除效果明显优于稻草滤料.以稻草-沸石双层滤料为过滤介质时,5 m/h的滤速下,CODCr、氨氮和磷的最大去除率分别达47 9%、72 9%和50 1%.研究表明,吸附-过滤预处理不仅能去除养猪废水中的CODCr、氨氮和磷,还能去除一定量的小分子有机物和臭味,同时附着大量固体有机物的稻草和吸附有氨氮、磷的沸石经过处理后可作为土壤改良剂或肥料,从而实现了农业固体废物的资源化利用.

| Abstract: | This paper is aimed to introduce a pre-treating process for swine wastewater proposed by the author so as to lower the pollution rate of the wastewater as well as to recover the nutrients in it. As a matter of fact,swine wastewater contains high concentrations of ammonium and phosphorus but may lead to serious pollution in the country. Besides,it is also very difficult to meet the discharging standards if only the generally secondary biological processing method is used. However,here we know that the swine ... |
