The filter packing includes filter cotton, three-dimensional surface and rattan cotton, is attached with nitrifier, bacillus, lactic acid bacteria, yeast Bacterium and pseudomonad, wherein the volume ratio of filter cotton, three vinylon and cotton blends and rattan cotton is 1: 2: 2.The aerobe filler includes ceramics Ring, glass ring, glass pumice etc., the adsorption stuffing include charcoal, zeolite, volcanic rock, active carbon, fine sand, gravel, wheat meal Stone etc. adheres to nitrifier, bacillus, lactic acid bacteria, saccharomycete and pseudomonad, wherein ceramic ring, glass ring and glass pumice Volume ratio be 1: 1: 3, the ratio of volcanic rock and other adsorption stuffings is 4: 1.
The filter packing the preparation method comprises the following steps: according to the inoculum concentration of 10~100mg/L by nitrifier, saccharomycete, lactic acid Bacterium, bacillus and pseudomonad are inoculated into filter packing matrix, and with oxyty lower than 2.0mg/L, pH value is 7~8 The natures such as river, lake, the library pool or the pending water of artificial sewage the filter packing matrix after inoculation is cultivated, cultivate When oxyty is gradually increased in sewage until 3~5.0mg/L, when water outlet ammonia nitrogen removal frank reaches 50% and haze reduction 70% When above, filter packing is obtained.
The composition of artificial sewage are as follows: NH4- N 30mg/L, CH3COONa 15mg/L, KHCO3300mg/L, KH2PO4 3mg/ L, FeSO4·7H2O 5mg/L, CaCl2·2H2O 5mg/L, MgSO4·7H2O 6mg/L, EDTA 4mg/L, microelement 1mL/ L；
The trace element suite becomes: CuSO4·5H2O 0.1mg/L, ZnSO4·7H2O 0.2mg/L, CoCl2·6H2O 0.1mg/L, MnCl2·4H2O 0.6mg/L, NaMoO42H2O 0.1mg/L, NiCl2·6H2O 0.1mg/L, NaSeO4 0.1mg/L, H3BO3 0.012mg/L。
The aerobe filler and adsorption stuffing the preparation method comprises the following steps: according to 50~80mg/L nitrifier, 20~40mg/ L yeast, lactic acid bacteria, bacillus and pseudomonad are inoculated into respectively in aerobe filler matrix or adsorption stuffing matrix； After being reacted lower than 2.0mg/L, the nature of pH value 7~8 or artificial sewage by the up flow type aerobic reactor with oxyty Obtain Aerobic Process for Treatment water outlet；When ammonia nitrogen removal efficiency reaches 90% or more, aerobe filler and adsorption stuffing are respectively obtained.
After the floatation type sewage-treatment plant starts successfully, floatation type sewage-treatment plant is put into ammonia nitrogen concentration and turbid It spends in higher polluted river channel, entire bioreactor is swum on river surface, and through detecting, the water quality in the black foul sewage water river refers to It is designated as: NH410~20mg/L of-N, 33~42mg/L of turbidity 212mg/L, pH 7.45-7.52, COD.
Continuous operation 20 days, ammonia-nitrogen content, turbidity and the COD value situation of change of water outlet are monitored daily, as a result as schemed Shown in 3-5.
As can be seen that using of the present invention while removing ammonia nitrogen and reduce the method enhanced the transparency of turbidity and can go rapidly Except the ammonia nitrogen and suspended matter in sewage, the removal rate of ammonia nitrogen can achieve 90% or more, and the removal rate of turbidity reaches 95% or more. The COD value of water outlet can also be effectively reduced, water outlet can be directly discharged into nature or artificial water so that treated, circulation benefit With.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects Describe in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in protection of the invention Within the scope of.
