Water quality test

The water quality test demonstrates that 3-NP , 2,4-DNP and 2,6-DNP are all non-easy to degrade .

根据水质指标测试结果，3-NP、2,4-DNP和2,6-DNP均属于不易生物降解的物质；

But there also appeared some problems due to unsoundness , such as lack of emphasis on water quality test resulting in mass criticism , and clashes with end-users dissatisfied with forcing them to install water meter .

但是由于公司的不完善，也出现了一些问题，如对水质化验不重视遭到了人们的批评，强制用户安设水表而导致与用户的冲突。
