The Application Of Fluid Can Be Clear (acf32) Governance Xibahe Water Test Research

Scarcing of water resource is a cosmopolitan problem. Whereas our country has limited water resources, average occupation is 1/4 of the international occupation. On statistic, China is one of the twelve deficient water countries. With the progress of city industrialization, developing of industry and agriculture and increasing of population, a great deal untreated water is drained into lakes. This will result in N> P enrich, algae abundant, water color green or brown strongly, smell odorous in these receiving water. In the end water is eutrophicated.Xiba river is one of the 22 rivers which go into the Dianchi lake in Kunming. It has accepted untreated domestic sewage for a long time and the river water is organic pollution severely. The result of water quality monitoring in the Xiba river indicated that some main water pollution index such as BOD₅ COD TN . TP and turbidity were higher than the water quality standard. In order to treat the polluted water in Xiba river, and to prevent the eutrophication of the Dianchi lake turning worse, the treatment on Xiba river water is on necessarily.Aqua Clean(ACF32) were added into the river when the trial carrying on. The Aqua Clean(ACF32) is a liquid microorganism product produced in Ecological laboratory INC in the USA. The Aqua Clean (ACF32) which contains 32 species bacteria was designed to treat organic pollution waste water from industry, agriculture and living. It has good result on reducing bad smell from water and decreasing COD BOD₅ oil and fat concentration in waste water. In order to stay as more microorganism as possible in the river on trial, tube biological carriers were set in the river. In the period of the trial carried on, some water pollution index as BOD₅ COD TN TP SS pH turbidity and species of microorganisms were monitored every week. The experiment result suggested that when the PH of the water is suit for the bacteria living, the Aqua Clean(ACF32) can not change the pH of the water. Three weeks after the trial began, bad smell was decreased, and six weeks later the bad smell was basic eliminated. On the trial period theBOD₅ COD TN TP. turbidity respectively reduced by 5.4%⁵7.8%. 10.9% 48.59 4%⁴2.5%. 6%⁴6% 10%⁶0%. The examination of microorganism alsoexpress, the categories of the algae in the river increased, the quantity of the blue-green alga reduced, and in the end time of the experiment some xenognous animals as wheel animalcule and sagitta also appeared. The esthetic quality of the water body turn better in the end time of the trial.In order to know the principles of the Aqua Clean (ACF32)better, a dynamic model of BOD5 degradation by micorgnism in Aqua Clean (ACF32) was developed,S?S0---jl-Kd —It. The mechanism of aerobic digestion, anaerobic decomposition,Y\ 61denitrification process, phosphors removal and deodorization by bacteria in Aqua Clean(ACF32) was suggested briefly. The problems existed in the process of the trial were analyzed. It was pointed out that low temperature, no fixed the microorganism, low concentration of substrate, complication surroundings of the river, large river discharge, shortage of the adding microorganism, bacteria predated by microanimals and leaching of the microorganisms may be the reasons of low efficiency of pollutants get away. It suggested that this kind of trial would be done in high temperature season and it is important to prevent the leaching of the microorganisms and to keep the quantity and activity of the microorganisms in the system. The survival and contribution of the bacteria added in the river need further research still.
