A sewage treatment plant with a daily capacity of 100,000 tons will produce 100 tons of wet sludge per day.
Wastewater treatment plant in the purchase of sludge treatment equipment should first calculate the amount of sludge generated daily, the amount of sludge generated here, including sewage treatment of sludge generated by each process, as well as treatment of the final sludge.
There are many reasons that affect the sludge production of a sewage treatment plant, including the sewage treatment process, as well as the impact of water quality is relatively large. Put into production sewage treatment plant, generally 10,000 tons of sewage will produce more than 10 tons of sludge, the sludge has a high water content, generally more than 80%. And sewage treatment plants are required to be equipped with appropriate sludge treatment equipment, sludge reduction, harmless treatment before transported outside the sewage treatment plant.
Sludge press dryer, sludge filter press and so on through the use of a number of sewage treatment plants, can be more than 90% of the water content of the sludge pressure drying into the water content of 40% of the mud cake, so that the volume of sludge reduced to the original 1/10, a large degree of realization of the sludge reduction, not only to facilitate the transportation, but also to solve the problem of a large area, the scope of pollution.
Through the above data can be roughly estimated, if a sewage treatment plant daily sewage treatment capacity of 100,000 tons, will produce 100 tons of wet sludge. Therefore, it is also necessary to handle not less than 100 tons / day of sludge treatment equipment, in order to run smoothly, not due to sludge disposal problems affecting normal operations.
The amount of sludge in urban sewage treatment plants in accordance with the statistics of a number of cities in the South; 10,000 tons of sewage treatment plant annual average value of 1 ton / day of absolute dry sludge, equivalent to
Containing a water content of 80%, the production of 5 tons of sludge. 100,000 tons of sewage treatment plant with a water content of 80%, the production of 50 tons of sludge / day.
Generally a little more in summer, a little less in winter.
Sewage treatment (sewage treatment, wastewater treatment): the process of purifying sewage to meet the water quality requirements for discharge into a body of water or reuse. Wastewater treatment is widely used in construction, agriculture, transportation, energy, petrochemicals, environmental protection, cityscape, medical care, catering and other fields, but also more and more into the daily life of ordinary people.
There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods.
Sewage treatment plants: some people surveyed more than 100 large treatment plants, half of the sun it, there is insufficient funds \ high cost \ low efficiency, the general efficiency of less than 70%, a low of only 40%.
