摘要

[目的]探究影响涝池水体水环境质量的主要原因,以期能为涝池水体水环境保护和水质状况改善
提供科学依据。[方法]从涝池的功能、容量、面积和结构等方面出发,选取陕西省杨凌农业高新技术产业示
范区8个具有典型代表性的涝池,对涝池水体 pH 值、溶解氧、化学需氧量、氨氮、总磷、总氮进行测定,同时对
水质样本点各污染物指标进行参数检验,并应用单因子指数等方法对其综合评定。[结果] ① 点源污染型涝
池在不同采样点位置水体污染物浓度差异显著(
p <0.05 ),各涝池总氮、总磷平均浓度范围分别为: 4.70~
78.13mg / L , 0.03~4.27mg
/ L ;氨氮平均浓度范围为0.36~39.18mg / L ;化学需氧量平均浓度范围为33.0
~1 067.40mg / L ;溶解氧平均浓度范围为1.5~7.3mg
/ L ;
pH 值大小平均值范围为7.85~8.64 ; ② 大部
分涝池水体污染严重,水质均为劣 Ⅴ 类,污染物主要以氮类污染物指标为主; ③ 调查区涝池水质污染程度
排序为:点源污染 + 有措施 < 面源污染 + 无措施 < 点源污染 + 无措施。[结论]布设污水处理设施及池底
防渗措施对于改善涝池水环境状态较为重要。此外辅以内源水体的相关修复及管护工作,效果将会更好。

其他摘要

[ Objective ] The main factors affecting the water environmental quality of water storage ponds were
explored to provide a scientific basis for water environmental protection and water quality improvement of
water storage ponds. [ Methods ] Eight typical water storage ponds in Yangling Agricultural Hi - tech Industries
Demonstration Zone of Shaanxi Province were selected , taking into consideration the function , capacity , area ,
and structure of the ponds.Six water quality indicators were measured : pH value , ammonia nitrogen (
AN ),
dissolved oxygen ( DO ), chemical oxygen demand ( COD ), NH + 4 - N , total nitrogen ( TN ), and total phosphorus
( TP ) .The multivariate statistical method and the single factor index were used to determine the variance of the
pollutants in the water quality samples. [ Results ] ① The concentration of water pollutants in the waterstorage ponds was significantly different at different sampling points (
p <0.05 ) .The average TN and TP
concentration in each pond was between 4.70~78.13 mg
/ L and 0.03~4.27 mg / L , respectively ; The
average NH + 4 - N concentration was between 0.36~39.18mg / L ; The average COD concentration was between
33.0~1 067.40mg
/ L ; The average DO concentration was between 1.5~7.3mg / L ; The average pH value
was between 7.85~8.64 ; ② Most water storage ponds were seriously polluted.The water quality was
inferior to the Ⅴ category , and the pollutants were mainly nitrogen - based.③ The pollution levels of the
water storage ponds in the survey area were : point source pollution+ measures<non
- point source pollution+
no measures<point source pollution+no measures. [ Conclusion ] The installation of sewage treatment facilities
and anti - seepage measures at the bottom of the pool were essential for improving the water environment of the
water storage pond.A better result would achieved if the measures are supplemented with the repair and
management of endogenous water bodies.
