城市生活垃圾综合处理系统的选择

以上海城市生活垃圾处置为对象，利用层次分析方法，选择了分选回收＋堆肥＋卫生填埋的综合处置系统，并且确定了堆肥方式应首先考虑仓式静态好氧堆肥。经过运行费比较，所选择的综合处置系统比现行的处置系统具有明显的优势。

底泥疏挖工程对草海水生生态环境的影响预测

草海底泥疏挖工程的实施，必将对草海水生生态环境产生影响，预测结果表明，疏挖后草海水质有所改善，基本达到国家地面水Ｄ类标准，但相当长时间内仍疳保持富营养化状态，生态系统短期内改善不大，需较长时间，依靠人工强化恢复和自然恢复。草海水生生态系统方能逐步恢复。     

染化废水厌氧生物处理技术的研究

鉴于厌氧微生物对偶氮染料的还原裂解作用，开发了以易降解工业有机废水作为外加碳源的染化废水厌氧生物处理的新技术．试验结果表明：在进水ＣＯＤ３１００—３５００ｍｇ／Ｌ，ＣＯＤ总／ＣＯＤ染化比值４０，ＨＲＴ３．０ｄ下，ＣＯＤ去除率＞８０％，最低染化ＣＯＤ去除率＞４５％，色度去除率＞８５％；实验证实，在厌氧处理过程中，染料组分的结构已发生了明显的变化；反应器内的污泥大多呈颗粒状；污泥活性和工艺性能可控制工艺运行参数得以维持．     

Test of membrane bioreactor for waste water treatment in a petrochemical complex

Membrane bioreactor (MBR) used in water and waste water treatment is a developing technique for water pollution control and water reuse. This paper describes a membrane-bioreactor for treatment of waste water in a petrochemical complex. The experimental MBR was a lab scale one composed of an activated sludge bioreactor unit and an ultrafiltration membrane unit. The relationship of COD removal with MLSS and HRT in this MBR was studied. The effects of crossflow velocity, backwash interval and volume of flush liquid on the flux were discussed. The results showed that average removal of COD, oil, SS and turbidity in petrochemical waste water by the MBR was 91%, 86%, 92% and 99% respectively. The average removal of NH₃-N and total phosphorous was 85% and 82%. A coefficient of COD removal, k, was 0.017-0.080 L/(mg.d). The membrane flux maintained higher than 60 L/hm2 bar for 34 days without chemical cleaning when the velocity of crossflow was 3.5-3.9 m/s and the backwash interval was 30 minutes and backwash duration at 20 seconds. The results indicated that it is feasible for MBR technology to be used in petrochemical waste water treatment. The treated water could be considered as a source used to make up water for industrial cooling system or to be reused for other purposes.
