摘要： PURPOSE:To remove phosphorus, BOD, SS and ammonia at high speed and in high degree with a single vessel by adding particulates of dense iron hydroxide and/or aluminum hydroxide to a phosphorus-containing org. sewage, then introducing the sewage to a packed layer fixed with microorganisms under an aerobic condition. CONSTITUTION:A slurry 6 of dense iron hydroxide particulates having large phosphorus adsorptivity is added to the phosphorus-containing org. sewage 1 such as sewerage, and the sewage is stirred in a pipeline 10 and flowed into the packed layer 3 in an aerobic biological filter device 2 from an upper side of this device. In this case, aluminum hydroxide is exemplified as the particulates having the phosphorus adsorptivity other than the iron hydroxide. Moreover, both of the iron hydroxide and aluminum hydroxide may be used. Then, the phosphorus is adsorbed and removed quickly by the dense particulates of the iron hydroxide, etc., and SS in the sewage is captured by a biological membrane of the filter device 2 to be filtered and removed. BOD and ammonia are also removed biologically with microorganisms sticking to the filter material, and a clarified treated water 7 flowing out from a lower part of the filter device 2 is obtained.

摘要： PURPOSE:To stably obtain a high nitrogen removing rate by obtaining a treated water by supplying a part of a denitrificated liq. to a biological nitrification part and circulating it and bringing the other part thereof into contact with a substance having a selective ion exchange performance to ammonia. CONSTITUTION:The treated water in which NOx is searcely contained and ammonia is allowed to remain intentionally is obtained by introducing a treated water containing an activated sludge from a denitrification part to a sedimentation tank, then, a relatively small amount of residual ammonia in the treated water is removed by a selective ion exchange by using the substance having the selective ion exchange performance to the ammonia such as a zeolite based mineral. In this way, nitrogen content in an org. sewage such as NOx and ammonia is efficiently and sufficiently removed. That is, the high nitrogen removing rate is stably obtained by combining a biological nitrification.denitrification process and the selective ion exchange process in a novel form.

摘要： PURPOSE:To recover phosphorous from sewage by bringing hydrated iron oxide particles and zeolite particles into contact with raw water to make ammonia nitrogen and a phosphate ion absorbed in raw water and bringing both particles into contact with an NaOH soln. and subsequently adding Mg to the NaOH soln. to precipitate NH4MgPO4. CONSTITUTION:Sewage is brought into contact with zeolite particles and hydrated iron oxide particles in an A-process and ammonia nitrogen (NB3-N) in sewage is removed by the ion exchange action of zeolite particles and a phosphate ion (PO4 ) is adsorbed and removed by hydrated iron oxide particles. Both particles are brought into contact with an NaOH soln. in a B-process to take out NH3-N and PO4 in the NaOH soln. Further, Mg is added to the NaOH soln. containing taken-out NH3-N and PO4 in a C-process and phosphorus is precipitated as NH4MgPO4 to be recovered. Treated water after the contact with the particles is reutilized in desorption as the alkali soln. after the recovery of NH4MgPO4 to be recovered to the C-process.
