Background: Decreasing of sea cucumber resources on numbers and size of fishing capture in Negeri Porto waters influenced its community structures. Further, water environment steadiness will questionable. For this reason, study was done to analyzed community structures of sea cucumbers include of numbers species found, density, potency, species presence frequency, distribute pattern, ecology index and environment measurement. Method: Research done on February to May, 2008 at Negeri Porto used Line Transect Method. Result: showed there were eight species of sea cucumbers found (potency as much as 12.286 individuals). Bohadschia marmorata got highest in numbers species found, density, potency and species presence frequency. There were three distribute pattern of sea cucumbers found wich are uniform, random and group. Conclusion: Sea cucumbers diversity was in lower, species are closed to compatible. B. marmorata and Holothuria edulis are tends to dominate this water. Environment factors such temperature, pH, salinity, DO, turbidity, current and sediment distribute showed that Porto waters was suitable to sea cucumbers growth.

In this paper, investigation and analysis on the operation of 3 combined wastewater treatment plants in sunny and rainy days in Wuhan city was made. The operations of lifting pumping stations in these plants were inspected. During sunny days, the processing units and equipments in these plants run in nearly full load and the load can only increase in a small quantity in rainy days. But the total waster water quantity in Wuhan in rainy days would reach to ten times more than wastewater quantity in sunny days. A large amount of untreated wastewater overflows from the channels to the bodies and causes heavy pollution to the water environment.
