Therefore, lake sediments have recorded eutrophication process of Lake Dianchi from oligotrophic lake to eutrophic lake. Especially in the past several decades, both autochthonous and allochthonous organic matter display rapid increasing. Combined with isotopic data, a conclusion is drawn that Lake Dianchi has entered into a hypereutrophic stage.

因此，湖泊沉积物记录了滇池从一个贫营养的湖泊演变成富营养化湖泊的过程，特别是最近几十年，滇池内源有机物和陆源有机物的输入都呈现快速增长的趋势，结合同位素组成特征表明滇池进入了重富营养化阶段。

The sewage flows from pool to plant, passing through retention reservoir to adjust PH value, into removing ammonia with temperature increasing to 20℃,into UASB reactor with temperature increasingto 35℃ to remove off COD and ammonia under the function of anaerobia, then into SBR reactor to remove BOD under the function of aerobia. When the biochemical disposal is completed, the processed sewage will come into the UF system to remove adsorbed solid, organic matter, bacteria, and pathogens in waterand finally come into the RO system to remove off dissolvable salinity, colloid, organic matter, and microbe in water.

垃圾渗滤液经储存池进入污水处理厂，经调节池调整PH值，经1#加热器升温到20℃进入氨吹脱塔脱氨氮，再经2#加热器升温到35℃进人UASB生物反应器，在厌氧菌的作用下降解COD和脱氮，再进入SBR生物反应器，在好氧菌的作用下降解BOD，完成生化前处理后转入UF超滤中空纤维膜系统进行分离处理吸附固体、有机物、细菌、病原体等；最后经高压泵送入进口的RO返渗透中空纤维膜系统中，进行分离处理可溶解盐分、胶体、有机物、微生物等。

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.
