Seaweed extract-EClean was applied to treatment for eutrophication water. Quantative detection of nitrogen cycle bacteria showed that seaweed extract could improve the growth of ammonifying bacteria, nitrosobacteria and nitrobacteria in the treated water. There was also an increasing trend in the number of denitrifying bacteria in aerated treatment water, which showed that the seaweed extract could accelerate nitrogen cycle and the release of nitrogen from water.

利用国外引进的海藻提取物EClean制剂对富营养化水体进行处理试验,经过定量测定处理和对照水体中氮循环细菌数量的变化,得出EClean制剂能够促进水体的氨化细菌、亚硝化细菌、硝化细菌的生长,并维持了曝气条件下一定数量的反硝化细菌,通过此处理使得在同一反应器中、同一条件下完成硝化作用和反硝化作用成为可能,加速了水体的氮素循环,使水体总氮下降明显。

The number of autoterophic bacteria were significantly lower than the heterotrophic bacteria. Majority of 21 strains of heterotrophic bacteria that isolated from water body were Pseudomonas. Majority of 25 strains of heterotrophic bacteria isolated from sediment were bacillus, microccus and Pseudomonas.Three genus of autotrophic bacteria were sulphuret bacteria, nitrify bacteria and nitrosobacteria that were capable of oxidizing H2S, S, FeS, oxidizing NH3 to NO2 and NO2 to NO3 respectively.

试验稚鳖池水中共分离出21株异养细菌,其中优势菌为假单胞杆菌属细菌;底泥中共分离出25株异养细菌,其中优势菌为芽胞杆菌属细菌,微球菌属细菌假单胞菌属细菌,三种自养细菌分别为具有氧化硫化氢、元素硫或硫化亚铁的硫细菌;具有氧化氨为亚硝酸的亚硝化细菌和能将亚硝酸进一步转化成硝酸的硝化细菌。

The paper studied the effects of submerged macrophyte and immobilized bacteria on the distribution of four bacteria communities: ammonifying bacteria; nitrosobacteria; nitrobacteria and denitrifying bacteria in water column and sediment of eutrophicted water.

本试验研究了沉水植物伊乐藻和固定化微生物两者相结合对富营养化水体和底泥中4种菌群的氮循环微生物(氨化细菌、亚硝化细菌、硝化细菌、反硝化细菌)分布的影响。

Nitrosobacteria was selectively cultivated on the biofilm and short-cut nitrification was achieved in 4 weeks by controlling the following conditions as HRT=1 d, DO=0.5—1.0 mg·L-1, pH of about 7.5, T =30℃ and no sludge recycle.

结果表明,在控制HRT=1 d、温度30℃、DO=0.5~1.0 mg·L-1、pH=7.5左右、无污泥回流等条件下,经过4周的运行,成功地选择培养出亚硝化型生物膜,实现了短程硝化。

According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.
