On the up-flow biological aerated filter to remove COD and NH3-N were studied the effect and contrast in various stages of finding the optimal operating conditions, so as to achieve energy conservation, the purpose of reducing operating costs. Through experiment studied that the variation of air-water ratio, hydraulic loading, organic concentration in the removal of COD and NH3-N effects, observe and analyse the change of COD and NH3-N removal and the characteristics of microorganisms of filter’s different height. The results showed that COD and NH3-N removal are high under the condition of air-water ratio 4:1~5:1, hydraulic loading 1~2 m3/ (m2●h), organic concentration 300~400 mg/L. The concentration of COD and NH3-N of effluent which are treated by biological aerated filter can meet with second degree discharging standards.

Aerated Filter

Filler plays an important role in biological sewage treatment technology. In the purification of urban sewage river, the single sponge iron filler is easy to harden. The combination of sponge iron and ceramsite can hinder the hardening and improve the removal efficiency. In this paper, scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the fillers. The removal efficiency experiments were carried out through the self-designed biological aerated filter (BAF) reactor with sponge iron and ceramsite mixed fillers, and the microorganisms attached to the surface of the biological fillers were qualitatively and quantitatively identified through 16S rDNA. The results indicate that the presence of Fe3O4, Fe2O3, Fe3C, and Fe2CO3 in sponge iron determines that sponge iron has strong reducibility and provides electrons for efficient denitrification. NaAlSi3O8 in ceramsite filler plays a significant role in phosphorus adsorption. In #3, #4, and #5 reactors (the mass ratios of sponge iron and ceramsite were 1 : 1, 3 : 1, and 1 : 3, resp.), the removal efficiencies of mixed fillers are good on chemical oxygen demand (COD), total phosphorus (TP), and nitrogen (N), and the more the ceramsite fillers in the reactors are, the higher the microbial abundance and diversity are. The mixture of sponge iron and ceramsite can be used to purify urban sewage river. A scientific basis to purify the polluted water body of urban rivers in situ is thus provided.

Reactor Operating

In order to study the pollutants removal effect, the reactor operating conditions were studied with Biological Aerated Filter　(BAF)　process. The results showed that when HRT was at 8h, the effluent COD and ammonia nitrogen were 37 mg/L and 8.6 mg/L with the aeration flow was 0.3 m3/h, the effluent COD and ammonia nitrogen were 53 mg/L and 12.2 mg/L respectively. And the range of effluent pH is at 6.0-8.8. Furthermore the effluent COD was stable, while the effluent ammonia nitrogen will gradually affect by aeration flow. So the BAF process for residential sewage treatment is feasible.

The blast furnace water quenched slag has characteristics such as porous and superficial roughness, so it can be modified and cranked out a filter media. The treatment efficiency of domestic sewage with water quenched slag biological aerated filter (BAF) was researched in this paper. And the removal rate of organic compound, ammonium, SS, and chroma was also investigated. The results showed that the quality indexes of the domestic sewage after treatment met the primary standard of the national integrated wastewater discharge standard (GB8978-1996). So the purpose of the waste harnessed by other waste is achieved. The applicative prospect of blast furnace water quenched slag on domestic sewage treatment is very broad.

Two Stages

The FM-AS process is a two-stage aerobic process consisting of a submerged biological aerated filter packed with fibre media as the first stage and activated sludge as the second stage. A separation unit working on the principle of dissolved-air flotation is needed between the two stages to remove the solids and thereby maintain a suitable sludge age for nitrification in the second stage. The FM-AS process produces effluents with good qualities. The highest removal efficiencies, obtained with a hydraulic retention time of 4.6 hrs. and an operating temperature of 16°C, for BOD5. NH3-N and SS were 95%, 95% and 90% respectively. The economic evaluation suggests that the FM-AS process can be more cost effective than the traditional activated sludge process, particularly when used for upgrading.
