冷却塔生物黏泥收集的物理排污装置的应用及实践OA

Based on the adhesion mechanism of biological sludge,a set of devices suitable for biological sludge adhesion was constructed in the water collection tray of cooling tower to collect biological sludge and discharge sewage by using physical means such as adsorption,barrier,filtration,and precipitation.After field application,water quality analysis and comparison results showed that the conductivity decreased from 2369.12 μs/cm to 998.2 μs/cm,the turbidity decreased from 11.92NTU to 7.16NTU,the average increase of COP of refrigeration units is 0.41.Practice has proved that the use of the physical sewage discharge device for biological sludge collection in the cooling tower has achieved the expected goals.Due to the continuous improvement of industrial circulating water,the heat transfer efficiency of the cooling tower and refrigeration unit can be gradually improved and the frequency of equipment cleaning can be reduced.
