查询词典 exceed proper limits

It was emphasized that GB3838-2002 not only need to pay attention to the full treatment of wastewater and rainwater but also the proper disposal of treated wastewater which meet the national discharge standard GB18918-2002 but still contain significant amount of pollutants if compare with the national surface water quality standard GB3838-2002. To the brooky region of Jiang-Zhe Plain, the discharged pollutant loads still significantly exceed the environmental capacity of the receiving waters even if all treated wastewater meet the first grade B limits of GB18918-2002, and the water pollution problem still cannot be really eliminated.

通过比较分析，我国现行的城镇污水处理厂污染物排放标准GB18918-2002和地面水水质标准GB3838-2002，明确提出，相对于这一区域的地面水环境质量而言，不但雨污水必须得到充分有效的净化处理，达标排放的污水中也仍然含有总量不容忽视的污染物质；对于江浙平原河网地区，即使全部城市污水都达到GB18918-2002中一级B的要求，排放的污染物负荷仍然会明显超过受纳水体的环境容量，水污染问题仍然难以真正消除；达标处理水的处置与利用问题值得特别的关注与探讨。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
