养殖场地表水污染特征研究——以某牧场为例

为研究现阶段我国养殖场地表水的污染特征,以某牧场为研究对象,对牧场的地表水采样点进行布置,并进行采样分析,采用单因素指数法进行了评价。结果表明,该牧场地表水受到了牧场废水的污染,污染由过去的废水不处理乱排放向废水收集不足产生的无组织排放转变,受污染的地表水流出该牧场后仍将对牧场的外环境造成一定的污染。为今后养殖行业环境污染治理提供科学依据。

For the study on the present pollution characteristics of the surface water in our country＇s farms, a ranch was taken as an example to set surface water sampling points of the pasture and make sampling analysis. And then the single-factor index method was used for evaluation. The results show that the pasture surface water was pollut- ed by the farm wastewater, the pollution problem of wastewater by the past discharging with no treatment changed to unorganized emissions caused by not enough collection. The polluted surface water has been discharged out of the ranch, but outside environment of ranch was still polluted. The research provides a scientific basis for environ- mental pollution control of feeding farms.
