Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Quality Indexes

A pharmaceutical factory in Wuhan produces many pharmaceutical wastewaters every day. The wastewater raw water quality indexes are: the concentration of COD,BOD5, NH3-N,TP is 300,000mg/L, 200,000mg/L, 450mg/L,900 mg/L ; By the SBBR treatment, the effluent water quality indexes are:750mg/L,350mg/L,1.20mg/L,5mg/L,and the effluent water can accord with Wastewater quality standards for discharge to municipal sewers (CJ 343-2010) and be discharged after treatment in the sewage treatment plant by municipal sewers.

Sewage Outfall

The adult dragonfly fauna and the larval fauna and abundance decrease markedly immediately downstream of the outfall from the Mimosa Sewage Treatment Plant into Bulimba Creek. The adult fauna is substantially restored farther downstream, but the larval fauna and abundance are not. Of the 36 species of Odonata observed at Bulimba Creek, the 10 abundant, essentially stream-dwelling species were most affected by the sewage effluent. Adults of only one of these stream species were found at the most contaminated site, and then only in very low numbers; those of two others were not observed downstream of the outfall. The diversities of both adult and larval dragonfly faunas give a qualitative indication of water quality. Parallels between the distribution or abundance of Odonata and the concentrations of contaminants indicate that chlorine may be the most important toxicant immediately downstream of the sewage outfall in Bulimba Creek.

Jinhae Bay

For the better understanding of long-term variations of water quality in Jinhae Bay after establishment of special law, we analyzed the archive data monitored in Jinhae Bay during the last 17 years (1997-2013). And change on fish catch due to the variations of water quality was investigated. A marked decrease in the number of red tide occurrence is due to the effectiveness of the law and sewage treatment plant that has targeted the reduction of COD in the effluent water since early 2000. Although the improvement of water quality, increase in fishery production was not observed in Jinhae Bay. For the recovery of fishery production, processes for restoration of entire ecosystem such as restoration of artificial intertidal flat and seaweed bed and remediation of organic-rich sea bed should be accompanied with improvement of water quality.
