Pulp and paper mill ranking fifth among the major industries for
water pollution problem in India. Its liquid effluent often
discharged in natural habitat impairs the health of ground water,
crop & soil and thus poses serious threat to the environment.
The land treatment of effluent costs negligible, requires thorough
understanding of soil-plant- effluent interaction. In view of this,
present study aims to assess the role of land treatment in
pollution removal from pulp & paper mill effluent. Three soil
column heights viz: 20, 40 and 100 cm for two soil textures
ST1(normal soil) and ST2 (normal soil: sand:: 1:1) were taken for
the study. Significant reduction in pollutants was found, when
effluent was passed through normal soil of 100 cm column height. As
the column height reduced, pollutant removal also reduced. Growth
of wheat plant was maximum at 50% effluent irrigation at sand mixed
soil. Study revealed that 100 cm soil column height resulted best
pollutant removal that hampers ground water pollution as well. Thus
the land treatment could be profitably practiced in Tarai and
Bhawar region of Uttaranchal, where 1 metre thick soil layer is
often available.
