单甲脒农药的微生物降解代谢研究

研究了门多萨假单胞菌ＤＲ－８菌株对单甲脒农药的降解代谢。该菌利用率甲脒作为生长的唯一氮源，其对单甲脒的呼吸作用试验确证了该农药的生物可降解性。单甲脒对细菌生物氧化代谢关联酶活性的影响研究表明，脱氢酶对单甲脒较敏感，而ＮＡＤＨ氧化酶则耐受性较强。

Optimizing the atmospheric sampling sites using fuzzy mathematic methods

A new approach applying fuzzy mathematic theorems, including the Primary Matrix Element Theorem and the Fisher Classification Method, was established to solve the optimization problem of atmospheric environmental sampling sites. According to its basis, an application in the optimization of sampling sites in the atmospheric environmental monitoring was discussed. The method was proven to be suitable and effective. The results were admitted and applied by the Environmental Protection Bureau (EPB) of many cities of China. A set of computer software of this approach was also comuletelv comniled and used.

Effects of environmental factors on the production and release of matrix-bound phosphine from lake sediments

Effects of pH, temperature, and oxygen on the production and release of phosphine in eutrophic lake sediments were investigated under laboratory tests. Results indicated that the elimination of matrix-bound phosphine was accelerated under initial pH 1 or 12. Phosphine levels could reach maximum under initial pH 10. The contents of phosphine increased with the addition of alkali under pH 4–12. The rates of phosphine production and release from lake sediments varied with temperature. 20°C was the most favorable temperature for the production of matrix-bound phosphine. Oxygen showed little effect on matrix-bound phosphine. Matrix-bound phosphine concentrations in lake sediments were concluded to be dependent on a balance of natural generation and depletion processes.

浅谈化工装置灾害事故的处置

化工生产一般采用温控分离、氧化还原、催化裂解、压力聚合等工艺方法,而化工产品特别是中间产品一般都具有易燃、易爆、有毒、有害和腐蚀等特点.在化工生产的过程中可能发生的各类灾害事故已经成为各级政府和应急救援单位研究的重要课题.下面结合工作实践谈谈化工装置灾害事故的处置思路.     

胜利石油局配气站噪声治理

本文对配气站管网系统作了噪声源分析，提出了在节流降压阀下游加装消声器，对管道作重点隔声包扎和简易隔声包扎、加装阀门局部隔声罩的方案。方案实施后，管网噪声由１２１ｄＢＡ降至８０ｄＢＡ，效果十分显著。     

宁夏灌溉回归水开发再利用的评价

宁夏灌溉回归水指灌溉农业土壤深层渗滤水、农田尾水、渠道渗漏水、退水及少量的工业废水和城镇生活污水,年排量３０～３５亿ｍ^３。对灌溉回归水２０种物质含量的评价表明,它属无毒有害型淡水。采取与渠水（来自黄河水）掺灌或轮灌对作物生长无不良影响,也不会引起土壤盐碱化,可大胆开发利用。
