the sludge organic complex fertilizer (Socf) for sugarcane, which contains 14.3% of itrogen, 4% of phosphoms oxide and 5% of potassium oxide. is made from municipal sludge after aerobic andzanaerobic fermentation by adding nitrogen, phosphoms and potassium properly Field experiinents show that: (1)Various fertilizers have a very weak influence onthe emergence rate, effective stem and sugar rate of sugarcane; (2)The output of sugarcane varies with the amount of SOCF applied infield and it is optiIllUm to apply 2 400kg ofthe fertilizer per hectare (3) 1he fertilizer effect of SOCF is superior to that of general complex fertilizer sold in nlarket and mixed fertilizer of urea, calcium-magnesium phosphate fertilizer and potassium chlonde when 2400kg of SOCF is used per hectare in field

在对广西兴安钨矿选矿废水水质分析的基础上，分别选择三氯化铁、精制硫酸铝、三氯化铝、聚合氯化铝和聚丙烯酰胺（PAM）作混凝剂进行了混凝沉淀试验，综合考虑处理效果即出水COD和浊度以及成本三氯化铁最为合适 三氯化铁的最佳投加量为合适；三化铁的最佳投加量为120mg/L，出水水质符合国家污水排放标准并能回用。最后提出了工程设计方案，此方案既防止了废水对环境的潜在污染，又解决了枯水期选矿用水不足的问题。

论述了UASB-SBR：理桂林漓泉股份有限公司啤酒废水的生化原理和系统调试、运行管理的工艺控制要点。工程实践表明，UASB-SBR工艺是一种有效地处理啤酒废水的工艺，uAsB池中颗粒化污泥成熟后，系统有很强的PH缓冲能力，不必加碱调节碱度；尽管啤酒废水缺乏氮源，UASB—sBR系统中的微生物能适应水质环境，处理后水质可达到国家排放标准。

应用微氧厌氧生物脱硫技术对糖蜜洒精废水进行了实验研究。结果表明，在温度为30℃，ORP，为-230mV，进水PH值为6.0条件下，COD去除率在40%左右，SO42-去除率在810%以上，单质硫生成率约为30%。

Guilin is a typical karst area where the hydraulic proximitv between surfaca water and ground water is close From the point of environ-mental conservation,karst aquifers are more vul-nerable than non-karst aquifers because their underground conduits provide no filtration There-tore, it 1s necessary to pay close attention to con-tamination from heavy metals in the groundwater if a sludge fertilizer. which USUaUv contains relatively large amount of heavy metals. is applied to the land surfaca in this area To determine the effect of sludge fertilizer and the possible toxicitv of heavy metals when the sludge of municipal wastewater is used in agriculture, a series of experiments was undertaken Firsfly, sludge was extracted from the sewage treat-ment plant of Guilin and the plant nutrient and heavy metal was than analyzed Secondlv'a complexorganic fertilizer of sludge (OCFS) was produced This OCFS was applied to rice land to determine itseffect as a ferilizer Lastlv. the heavy metal contents of agricultural products after application of OCFS were studied It ws shown that (1)there were large amounts of plant nutrients in the sludge: on average it contained 396%organic matter The content of total nitrogen, phosphorus, and potassium was 48 3, 21 1, and 85g/kg on average, respectively The heavy metal contents ofthe sludge are in accordance with the National Standard and, basicalh the sludge is suitable for agricultural application f2 The fertilizer of sludge was effective The output of rice was increased by 1819% when OCFS was used The effect of sludge fertilizer was better than that of a complex fertilizer sold on the market When sludge fertilizer was tested against others on the market, no difference could be found in the heavy metal content ofthe rice and rice stems Therefore. sludge fertilizer can be assumed to be safe and effective for agricul-ture f3 The extraction rate of heavy metals ranged from 23 to 60% when the sludge was extracted by O 1mol ofEDTA,i e, 23 to 60% ofmetals maybe absorbed by plants

广西涠洲石油终端处理厂污水Cr浓度在11000～12000mg/L平均为113480mg/L。CODcr约为150～400mg/l属高盐度污水。通过对徽生物进行驯化，仍可以用生化法处理。研究表明：单一的厌氧生化法和好氧生化法处理污水均不能达标，而厌氧-好氧联合处理效果良好，出水水质稳定。出水CODcr为14～67mg/L，可达到国家污水排放一级标准。
