摘要: Paper and pulp industries produce large quantities of wastewater which can have adverse effects on the receiving water systems. In present study lysimeters were used filled with different soils replicating natural soil horizons provided a leachate collection system. The physico-chemical characteristics in each lysimeter quality before leaching assessed. Treated was evaluated for crop irrigation, categorized according to irrigation class ‘Increasing Problem Severe Problem’ respect salinity specific ion toxicity. Sandy loam showed 96% chemical oxygen demand (COD) removal while clay removed 99% COD, colour both cases found be 100%. Application resulted an increase pH value, ranging from 6.2–7.6; electrical conductivity (ECe) saturated extracts 0.6–1.7 dS m−1, exchangeable sodium percentage (ESP) ranged 7.8–11....
