Grease - and efficient flotation coagulation - filtration process aluminum, carbon production and Wastewater Treatment

; Lmg / 1). 4, operating results and problems of a treatment project broke ground in August 1996 and lasted two years, in October 1998 officially run by the Environmental Monitoring Center Station of Guizhou Province acceptance monitoring shows that a variety of pollutants discharge standards have been achieved, greatly reduced the impact of the external environment, basically solved the problem of environmental pollution in the East Area. (Monitoring results see Table 4) two reuse project began construction in March 2000, 10 completed by the end, 12 end of the month to run. Put into operation, in order to investigate its effect, I at the station in conjunction with other monitoring departments conducted a comprehensive examination and analysis. (Test results shown in Table 5, Table 6), and recycled water from effluent water quality analysis results can be determined basically reached the second phase of the design requirements, super efficient flotation treatment effect is more obvious, though failed to achieve high fiber filter technology agreement requirements, but the water can reach me after the industrial water recycling plant to determine requirements. In particular, by the end of March 2000 the former carbon 1 # baking treatment change, the expansion project put into use,air jordan shoes cheap, carbon baking to achieve its own closed loop waste water, the source of high concentrations of wastewater been contained, the East Area water treatment system to reduce the load, resulting in Phase II treatment and reuse of water quality improved to some extent, to further ensure the water quality of water for industrial use. The East Area wastewater treatment and reuse project covers an area of 6784m2,ed hardy clothing, total investment is 6.46 million yuan (an investment of 2.96 million yuan, the second phase investment of 3.5 million yuan). Since the self-running, external displacement from the original 700m3 / h reduced to 300 - 400m / h, the efflux of waste reduction of about 300 million m3, 200 million in new water saving m3 or more, ease the contradiction between water supply tension, reduce production cost; basically solved the problem of pollution of external environment, to further improve the relationship between the environment and the workers and peasants, have made considerable economic benefits, environmental and social benefits. With the East Area of reclaimed water to continue to tap the potential of water points and development of two dealing with the recycling of backwater volume will further increase. At that time, will achieve further reductions in the East Area of fresh water, waste water full amount of recovery, no more than the basic row,stivali ugg, to achieve greater environmental, economic and social benefits of the unity of the three. However, the project has been running, but also start to appear some problems, first of all,ugg italia, back to the water color and higher phosphate concentration; Secondly, since the water used in oil and coagulation polyacrylamide (P) easy to apply knot in the high fiber filter fiber filter, causing rapid failure of the filter, cleaning frequent and complex. To further expand the use of recycled water needs further study and solve. * 52 * White Rainbow: grease and efficient flotation of a coagulation of a filtration process aluminum, carbon production and Wastewater Treatment 2002 12 Table 4 East Area sewage treatment station monitoring results Unit: mg / l (PH value than) the next day the first day of 7.1116.67159 7.4821.85122 import the third day of treatment facilities 7.1416.673520.7132.530.1870.2200.38413.1814.088.23 Table 5 Phase II Analysis of water quality test results of units: mg / 1 an import export 7.26-8.7930-68501 7.26-9.2072-2241352.1-17.98.84.3-209.1 one hundred and eleven .1-16.59.52.3-7.13.939-14170.5 flotation export 7.31-8.0420-4O305.5-12.99.61.5-2.01.762-8369 Export 6.18-8.148-21120.9-15.78.10.6-1.51.040-52465 filter conclusion is well known that the total water resources in China ranks sixth in the world, but the per capita amount of water are poor water state, and water pollution is getting worse. The emerging shortage of water resources situation, the reasonable use of water resources is an urgent task we face. Wastewater recycling, wastewater recycling is an important way to solve the problem of great practical significance and long-term strategic significance. I plant by electrolysis, carbon production and waste water treatment, reuse of engineering practice,air jordans, realized from the waste water discharge standards to recycling across, is a very good example.
