Ginkgo biloba tree is not the result soon, but after a very long time; not soon grow taller, and some grow only a few centimeters in the last few decades, we can imagine, now tall and strong of Ginkgo tree to go through many years of ups and downs, and now they are known as the vegetable kingdom before the "giant panda","living fossil" and therefore we have to protect them.

银杏树不是很快就能结果的，而是经过很长时间；也不是很快长高的，有的二三十年也不过长出几厘米，可想而知，现在又高又壮的银杏树要经过多少年的风风雨雨，到现在人们才把它们称为植物界的"大熊猫"、"活化石"所以我们要保护它们。

内存可以说是CPU处理数据的&大仓库&，所有经过CPU处理的指令和数据都要经过内存传递到电脑其他配件上，因此内存性能的好坏，直接影响到系统的稳定性和运行性能。

Through researching the mechanism of biological nitrification and denitrification and actual project application of the technology and related literature materials, the obtained results are as follows:(1) Anoxybiosis is effective to the removal of COD; after the anoxic process, BOD/COD of the outflow increases, it shows that the degradation ability of wastewater is improved; anoxybiosis is insensitive when shock loading of inflow wastewater varies greatly;(2) It is demonstrated by the operation of inoculation and cultivating that biofilm takes two weeks to succeed in cultivating on packings and the removal ratios of NH3-N and COD get 50% and 70% respectively, when gas-water ratio is 6:1, HRT is 7.3 hour, water temperature is above 15°C;(3) It is demonstrated that gas-water ratio, hydraulic loading, HRT, temperature, pH etc are important factors which influence the removal effect of pollutants, when the gas-water ratio is 6:1, hydraulic loading is about 0.38kgNH3-N/m~3.d, water temperature ranges from 15°C to 27°C, pH ranges from 7.5 to 8.0, the BIOFOR removal effect of pollutants is the best;(4) The operation indicated that, this technology has strong ability of nitrification and denitrification; it has extremely vital significance for reducing the water body eutrophication;(5) It is confirmed the feasibility and the usability of preanoxic-BIOFOR process to treat L-lactic acid production wastewater. The experiment indicated that the treatment effect of this technology is very good and also shows that the technology has many advantages, such as small volume, high treatment efficiency, good effluent quality and strong endurance to load variation, this technology is a new and economical wastewater treatment process.
