摘要：Solutions containing pesticide wastes from greenhouses, for example, aredecontaminated in a system including a soil bed reactor. Waste water from thegreenhouse goes to a sample tank from which samples are withdrawn for assay oftoxicity. Water from the sample tank goes to a holding tank, or to a downstreamsubsystem if toxicity level is low. Water in the holding tank is aerated to promotedegradation of toxic materials. Water from the holding tank is applied near the uppersurface of a layer of soil in the soil bed reactor. Air from the sample tank and holdingtank, and intermittently, air containing pesticides from the greenhouse, is also passedthrough the layer of soil in the soil bed reactor. Microbial action in the soil degrades toxicmaterials in both the gaseous and liquid streams. Water from the soil bed reactor maythen be discharged to a pond populated by plant and animal species which promotefurther degradation of any remaining toxic materials before the water is discharged fromthe system. A bioassay technique employing aquatic amphipods sensitive to water bornetoxic materials is provided for routine screening of toxicity levels in the various solutionsin the system.
