Beneficial effects of the present invention are embodied in：
Zeolite surface loads nano manganese oxide while not influencing zeolite ion exchange adsorption ammonia nitrogen, enhances to low
Fe in warm underground water2+、Mn2+Suction-operated, water outlet Fe can be made by the absorption of composite material2+、Mn2+、NH4 +- N concentration is same
When reach Drinking Water quality standard.
Mn oxide is loaded as raw material using natural zeolite and microorganism prepares multifunctional composite, in addition to adsorbing Fe2+、
Mn2+、NH4 +Except-N functions, also there is microbiological oxidation Fe2+、Mn2+、NH4 +The function of-N.
Operation is according to water inlet absorption, emptied of water, drum air bio-regeneration, washing nitrate four-stage sequencing batch operation.
Absorption phase of intaking is since water temperature is low, anoxic, and composite material surface is to Fe2+、Mn2+、NH4 +- N goes divided by is adsorbed as to lead, and nitrification is made
To be faint, nitrate concentration is also very low in not removing only ammonia nitrogen and being discharged, and nitrogen removal rate height overcomes current technology and deposits
Defect.
The drum air bio-regeneration stage, due to having emptied the water in adsorption column, without hydrostatic pressure, needed for blasting regeneration
Wind pressure, low energy consumption.In order to improve microbiological oxidation Fe2+、Mn2+、NH4 +- N metabolic activities improve 15-40 DEG C of blast air temperature,
Solve the problems, such as that microbial metabolic activity is low in the low water of low temperature.
Advantage of this approach is that not only eliminating the Fe in underground water simultaneously2+、Mn2+、NH4 +- N, and need not be over the ground
Lower water carries out aeration aerating.Its mechanism of action is ferrimanganic (hydrogen) oxide, the microorganism point of absorption phase, zeolite and its load
NH is not adsorbed4 +-N、Fe2+、Mn2+, not only rely on nitrifier in the blasting regeneration stage and complete absorption Ammonia Nitrification, and complete to inhale
Attached Fe2+、Mn2+Chemistry and biological oxidation in air, overcome the insufficient obstacle of oxygen in water.Microorganism nitrifies to be formed
Nitrate be individually discharged in the washing stage, without NH in water outlet4 +The nitrate of-N conversions.Improve the temperature of blasting regeneration stage air inlet
Degree can enhance the metabolic activity of nitrifier and Fe-Mn oxidation bacterium, shorten the recovery time, also overcome and cryogenically descend aquatic organism nitre
Change the obstacle of ammonia nitrogen removal.
