| 摘要: |
| 把亚铵法制浆废液当做复合肥料施入农田后,其增产效果早已为有关试验和生产实践所证实。对施用亚铵法制浆废液,人们最关注的问题有两个。其一是施用后对土壤主要性状有何影响?对此已有专文阐明。另一是施用制浆废液或综合废水对环境和土壤条件有无污染?其程度又如何?……等。此处仅就施用造纸综合废水对稻田地下水质量影响的有关内容加以介绍。为了解灌施亚铵法造纸综合废水对稻田地下水质量的影响,自82年春开始对北京农业大 |

| Abstract: |
| Productive experiments of irrigating rice fields with paper-making mixed effluents by the method of ammonium sulfite were made on the Experime ntal Farm which is situated on the sandy or sandloamed alluvial material by river Juma in Hebei Province. After irrigation with the above mentioned effluents,the quality of the ground water changed as follows. The total salt content was doubled,yet the ground water remained to be of high quality. The ratio of anious obviously changed:HCO_3~- decreased,Cl~- and SO_4~-... |
