【摘要】 根据黑龙江垦区绥滨灌区水量平衡关系及灌区排水水质采样监测资料,对灌区排水受纳水体黑龙江和松花江水质进行了预测。预测结果表明,在排水口下游5～10km范围内,黑龙江和松花江混合区域水质基本与本底接近,受纳水体对灌区排水有较大的稀释能力。为了进一步缓减排水对受纳水体的影响,提出了通过改造排水干渠、设置排水坑塘等途径净化灌区排水的建议。更多还原

【Abstract】 Based on water balance relationship of Suibin irrigation district and field data of water quality of drainage, the water quality of the receiving water bodies, the Heilongjiang River and the Songhua River, are predicted. It shows that the water quality of the mixing area, 5-10km downstream of the effluent, is close to the background water quality, indicating that the receiving water bodies have strong capacities to dilute the pollutants from drainage. In order to alleviate the impact of discharge on the receiving water, proposals such as modifying main ditches and establishing discharge pools are put forward for purification of drainage from the irrigation district.更多还原
