The aerobic biofilter module assembly system is an aeration biofilter, namely air or oxygen is fed from an aeration device arranged below a biological filter material layer during working. The aerobic microorganisms and the nitrifying microorganisms growing on the biological filter layer oxidize and decompose organic matters into carbon dioxide and water and oxidize ammonia nitrogen into nitrate.
The module assembly system of the anoxic biofilter is used as a denitrification biofilter without an aeration device, namely, air or oxygen is not fed during working. Denitrifying microorganisms growing on the biological filter layer reduce the nitrate into nitrogen gas to remove the total nitrogen.
The module assembly system of the anoxic biofilter is used as the anaerobic biofilter without an aeration device, namely, air or oxygen is not fed in during working. The anaerobic microorganisms growing on the biological filter layer decompose the organic matter into low molecular organic matter.
When sewage is treated, if nitrate nitrogen is not required to be removed, the primary aerobic biofilter module assembly system is used for removing organic matters and ammonia nitrogen in water, and the discharge standard can be met.
When sewage is treated, if organic matters, ammonia nitrogen and nitrate nitrogen are required to be removed, an anoxic biofilter module assembling system and an aerobic biofilter module assembling system are adopted to be connected in series for use, namely, the sewage firstly enters the anoxic biofilter module assembling system and then enters the aerobic biofilter module assembling system, part of the effluent of the aerobic biofilter module assembling system flows back to the anoxic biofilter module assembling system positioned at the upstream, and part of the effluent is discharged out of the system. The anoxic biological filter module assembly system used as a denitrification filter mainly reduces nitrate nitrogen into nitrogen and removes a part of organic matters at the same time. The aerobic biofilter module assembling system mainly oxidizes and decomposes organic matters into carbon dioxide and oxidizes ammonia nitrogen into nitrate nitrogen. After the sewage is treated by the system, the effluent can reach the discharge standard of level A and above.
The anoxic biofilter module assembling system and the aerobic biofilter module assembling system are divided into a downward flow mode, namely water passes through the filter layer from top to bottom, an upward flow mode, namely water passes through the filter layer from bottom to top, and a lateral flow mode, namely water transversely passes through the filter layer according to the water flow direction in the filter layer during working.
When the filter layer is cleaned, cleaning air passes through the filter layer from bottom to top, and cleaning water adopts an upward flow cleaning mode, or a cleaning water downward flow emptying cleaning mode, or a cleaning water upward flow water filling cleaning mode, or a cleaning water downward flow and upward flow alternate cleaning mode.
The downward flow washing, that is washing water, passes through the filtering layer from top to bottom, the upward flow washing, that is washing water, passes through the filtering layer from bottom to top, the downward flow emptying washing, that is washing water, passes through the filtering layer from top to bottom and is emptied, and the upward flow water filling washing, that is washing water, fills the filtering layer with emptied water from bottom to top.
The module-assembled biofilter system can be used for sewage treatment, polluted water source water treatment and lake water treatment, and can remove organic matters, ammonia nitrogen, total nitrogen and total phosphorus in water and simultaneously remove suspended matters in water.
The module-assembled biofilter system is formed by assembling the biofilter modules, so that the equipment of a sewage treatment plant and the production of a factory workshop are realized, the construction period is saved, the occupied area is saved, and the engineering investment is saved.
