海水水质标准 - Surplus environmental capacities of din and po4 - p were positive and remained constantly , relative to 1st grade environmental capacities , from late 1970s to mid 1980s , but it decreased sharply from mid 1980s to late 1990s
胶州湾din和po _ 4 - p剩余环境容量在20世纪70年代末至80年代中期变化较小，相对国家一级海水水质标准下的环境容量还具有约60的容纳能力。 - The measured values coincide well with the simulated ones . the result shows that as to cod and tp , the water quality is up - to the water standard , while to tn , it is not . seawater has been badly polluted in the north - east of jiaozhou bay
大沽河、墨水河和李村河入海口附近水质超四类海水水质标准( gb3097 - 1997 ) ：娄山河、红岛沿岸海域水质超过三类海水水质标准；胶州湾超一类水域的面积占湾内面积的64 。 - The value of surplus environmental capacity of din exceeded about 70 percent of the 1st grade environmental capacity in 1997 . since 1997 , the impact of nutrients pollution has begun to mitigate because of the enhancing protection of marine ecology by local government . the variation of surplus environmental capacities of din and po4 - p in jiaozhou bay implicated that the discharge amounts of din and po4 - p to jiaozhou bay were bearable from late 1970s to mid 1980s
