Ozone - Activated Carbon For Treatment Of Municipal Sewage

Currently, with under-water all has the different degree in the majority city lacks the water phenomenon, some cities lack the water phenomenon extremely are also serious, on the other hand the massive cities sewage and drains in vain, both wasted the resources, also polluted the environment. With the city for the water volume nearly equal city sewage in, only has 0.1% pollution matter, 3.5% are much less than the sea water in, major part is may the again use clear water, its regeneration processing is more inexpensive than the sea water desalination cost, the initial cost pilots the economy compared to the long-distance range many, moreover the city sewage nearby may result in, is easy to collect. Therefore, strengthens the city life sewage takes the second water source sales commission aspect the research work appears extremely urgently. This article tests is lives the sewage first carries on tires of oxygen friendly oxygen two levels of biochemistry processing, the water leakage in turn after the ozone tower, the ceramic filters again the tower and the activated charcoal tower carries on to it depth processing. The experimental result indicates: Two levels of biochemistry process its COD remove rate are about 70%, is lower to the total phosphorus and the total nitrogen degeneration rate, in particular in total phosphorus and total nitrogen content very high when processes the effect is not more ideal; Two levels of biochemistry processing water leakage if alone again passes through ozone tower processing, its COD remove rate is 36%, the total phosphorus and total nitrogen remove rate separately is 42% and 58%; Two levels of biochemistry processing water leakage if alone again passes through activated charcoal tower processing, then its COD remove rate is 50%, the total phosphorus and total nitrogen remove rate separately is 48% and 67%; Thus it can be seen, if two levels of biochemistry processing water leakage again independent employment ozone or activated charcoal tower processing, its water quality does not reach the sales commission request under the experimental condition, if increase ozone and activated charcoal amount used, although has the possibility make the water leakage water quality to improve, but the processing cost can greatly increase. Therefore, we studied two levels of biochemistry processing water leakage again in turn after the ozone tower, the ceramic filter the tower and the activated charcoaltower union depth processing craft again, this place principle craft its COD remove rate was 72.8%, anionic surfactant medicinal preparation remove rate was 90.9%, petroleum class remove rate was 78.8%, the total phosphorus and total nitrogen remove rate separately was 73.8% and 82.7%, the final water leakage might directly use in the city afforests, flushes the restroom, eliminates and washes the vehicle and so on, had the good environment, the society and the economic efficiency.
