手工翻译的，希望能帮上忙：
我国是一个以煤炭为主要能源的国家，大气污染呈煤烟型特点。控制煤烟型污染，特别是二氧化硫污染，最重要的途径就是烟气脱硫。目前应用的烟气脱硫装置中，80%以上是湿法脱硫技术，其中以石灰或石灰石-石膏湿法脱硫系统为主。
Coal is a dominant source of energy of China and the coal dominance has caused the atmospheric pollution featuring the emission of coal-burning flue gas, especially the sulphur dioxide. The most efficient way to address such problem is the deployment of flue gas de- sulfurization (FGD) system. Of the FGD systems currently in operation, plants with wet-process FGD method account for more than 80 percent and most of these systems are of limestone type or limestone-gypsum type.
脱硫石膏是石灰或石灰石-石膏湿式脱硫工艺的副产品，含有多种杂质，其抗压强度、抗拉强度等都无法与天然石膏竞争，再利用价值不大，不得不作抛弃处理，占用大量的土地。脱硫石膏还是一种危害严重的污染源，分解后的石膏粉末被风带入空气形成悬浮微粒，影响动物的健康和植物的生长，脱硫石膏经雨水冲刷渗入土地农田、污染地表水和地下水，进入我们的食物链。如不采取积极有效的措施，其释放的有害物质将对人类造成极大的伤害。
The FGD gypsum is a byproduct of the wet-process FGD using limestone or limestone-gypsum method. As the FGD gypsum contains excessive impurities, it is far less useful compared with the natural gypsum in term of the compression strength and tensile strength, hence often disposed of as waste due to its little value of reuse. The disposal of the FGD gypsum, however, requires heavy land use and may cause serious contamination. The discarded gypsum, when decomposed, may go with airflow into the atmosphere as suspended fine particles that will negatively affect the animal’s health and vegetation. The FGD gypsum may also go with the storm water into the cropland, contaminate surface water and ground water and get into our food chain. If we cannot take preventive actions against the potential contamination hazard, the FGD gypsum will cause serious harms to our human beings.
本文首先分析了脱硫石膏的基本特性和危害，介绍了国内外脱硫石膏的排放和应用情况以及胶凝材料综合利用研究现状。重点讨论了欧洲和国内对脱硫石膏的综合利用途径，从技术上、经济应用前景等方面进行了详细分析，找出国内对脱硫石膏应用的不足和存在的问题，提出了解决方案和建议。对脱硫石膏替代部分水泥作为矿山填充胶结材料的利用途径做了较为详细的试验研究，验证了该方案的可行性，并对脱硫石膏的综合利用途径进行了总结和探讨。
In this article, the writer first makes an analysis on the general properties of the FGD gypsum and the harm it may do to the environment. The writer then provides information of the FGD gypsum disposal and reuse at home and abroad, together with the current research of comprehensive use of the cementitious materials. The discussion is focused on how to make comprehensive use of the FGD gypsum in cases of European countries and China. Technical and economic possibilities are detailed to explore the reuse of the FGD gypsum product and identify deficiencies and problems in connection with the reuse of FGD gypsum in China. Solution and suggestions are presented to address the problems. This article also describes the detail test and study on the FGD gypsum used as alternative binding material for mine filling to partially replace the cement. The feasibility of the proposal is technically verified. Finally the writer summarizes the possible ways of comprehensive FGD gypsum reuse and some aspects deserving further study.

The our country is 1 to take coal as the nation of main energy, the air pollution presents a coal smoke type a characteristics.Control a coal smoke type pollution, especially sulphur dioxide pollution, the most important path is a smoke spirit to take off sulphur.The smoke spirit which applies currently takes off sulphur device in, 80% is an above wet method to take off a sulphur technique, among them with the lime or the limestone-gypsum wet method take off sulphur system is lord.Taking off the sulphur gypsum is the by-product that lime or the limestone-gypsum wet type take off a sulphur craft, implying various miscellaneous qualities, its anti-'s pressing strength, anti- to pull strength's etc.s can't compete with natural gypsum, again don't greatly make use of value, have to make to abandon a processing, take up a great deal of land.Taking off the sulphur a gypsum still 1 kind endangers a serious pollution source, the gypsum powder after resolving is taken by the breeze to suspend particle into the air formation, influencing animal of health and plant of grow, take off sulphur gypsum to was flushed by rain water to seep into land farmland and pollute earth's surface water and groundwater, get into our vegetative chains.Such as don't adopt actively valid measure, it releases of the harmful material will bring tremendous injury to mankind.
This text analyzed to take off basic characteristic and bane of sulphur gypsum first, introducing to take off sulphur gypsum to exhaust at home and abroad with application circumstance and gum 凝 material comprehensive make use of research present condition.The point discussed Europe and domestic to make use of path towards taking off sulphur gypsum of synthesizing, from the technique, economic application foreground's etc. carried on detailed analysis, finding out the problem of the domestic to take off sulphur gypsum apply not enough and existently, putting forward solution and suggestion.Filled gum knot material to make use of path to do a more detailed on trial research towards taking off sulphur gypsum acting for parts of cements aring a mineral mountain, verified the possibility of that project, and made use of path to carry on summary and inquiry into towards taking off sulphur gypsum of synthesizing.

China is a country using coal as her dominant energy source, whose air pollution shows soot pollution. The most efficient way to control soot pollution (especially SO2) is the deployment of flue gas de-sulfurization (FGD) systems. Eighty percent of current FGD systems adopts wet-process FGD, mainly limestone FGD or limestone-gypsum FGD. FGD gypsum being a by-product of the wet FGD processes mentioned above contains various impurities, whose compressive and tensile strengths are lower than that of natural gypsum, therefore, it has to be disposed due to its little recycling value, more seriously, the disposal of FGD gypsum requires large areas of land. FGD gypsum may cause serious contamination for the dust of decomposed gypsum forms suspended particles after brought up into air by the wind, affecting the animal’s health and plant growth. FGD gypsum may also permeate into the cropland with rain out, contaminate surface water and ground water, and go into food chain. If none positive measures were taken, the harmful substances emitted from FGD gypsum will cause serious harms to human beings.
The author firstly analyzed the general properties and damages of FGD gypsum, then introduced the disposal and application of FGD gypsum, as well as the integrated reuse state of cementing materials both in China and foreign countries. The author focused on the discussion of integrated use of FGD gypsum in Europe and China, then analyzed the technical and economic possibilities, and identified deficiencies and problems presented in the reuse of FGD gypsum in China. Solution and suggestions are presented to address the problems. This paper also described the detailed experiment on FGD gypsum used as alternative cementing material for mine filling to partially replace cement. The feasibility of the proposal is technically verified. Finally the author summarized the possible ways of integrated FGD gypsum reuse and some aspects deserving further study.

China is a major coal as energy, air pollution was smoke characteristics. Control coal pollution, particularly sulfur dioxide pollution, the most important way is FGD. Application of the current flue gas desulfurization equipment, with over 80% of wet FGD technology, with lime or limestone-gypsum wet desulfurization systems-based. Gypsum is lime or limestone-gypsum wet desulfurization process by-product, containing a variety of impurities, its compressive strength, tensile strength and so can not compete with natural gypsum, reuse of little value and has to be abandoned, use up a lot of land. Gypsum is a serious source of pollution hazards, the decomposition of gypsum powder by the wind into the formation of suspended particles in the air, the impact of animal health and plant growth, gypsum erosion by rainwater infiltration land farmland, pollution of surface water and groundwater, we enter the food chain. If we do not take positive and effective measures to release harmful substances will cause great human harm. This paper analyzes the gypsum to the basic characteristics and hazards, This paper introduces the gypsum emissions and application of cementitious materials and Comprehensive Utilization Research. Focused on the European and domestic gypsum to the comprehensive utilization of channels, technically, Application of the economy as well as the prospect of a detailed analysis to identify the domestic application of gypsum to the shortcomings and problems, proposed solutions and recommendations. Alternative part of the gypsum mine filled with cement as cementation material utilization to do a more detailed test, Verification of the program, the feasibility of a comprehensive utilization of gypsum ways summarized and discussed.
