回收

This text is in term of retrieving in recycle treatment, have described that discards the recycling current situation of the glass fibre both at home and abroad, and has analysed that recycles the question that exists in the course.

本文从资源化回收的角度，描述了国内外废弃玻璃纤维的回收利用现状，并分析了回收利用过程中所存在的问题。

This apparatus was designed based on summarizing the most synthetic processes of lactide presently.

本文在总结了目前众多聚乳酸单体——丙交酯的合成技术的基础上，选用减压蒸馏工艺并加以改进，设计出最佳的实验装置，使丙交酯的产率从30％提高到45％，并对重结晶后的母液进行有效的回收，回收率也能达到40％，对回收后的丙交酯进行了测试分析，证明了回收过程的可行性。

Accroding to the literature, the energy consuming of reclaim process was about 50%~60% of total cost of PVA production, while the energy consumption of methyl acetate recycling was about 70% of the energy consuming reclaim process.

有资料显示，整个PVA工厂的能耗有50～60%用于回收工段，而醋酸甲酯回收的能耗又占回收工段能耗的70%左右。

Investment return can be expressed as two parts: monitory return and non-monitory return.

投资的回收可以分为两个部分：金钱上的回收和非金钱的回收。

But this way there is still some problems: The first is the classification of garbage awareness is not strong, looks like a trash can in fact classified and former effect is the same; second, the boundaries of recyclable and non-recovery is unknown, some of the more a strict classification is not as familiar to the students; third is the credibility of recovered, often encounter such a situation, was classified as environmental protection staff in clearing rubbish is often peremptorily, when the inverted together, it will not be garbage separation effect.

但这样的方式还是存在一定的问题：第一是垃圾的分类意识不强，看似分类的垃圾桶事实上和以前的效果是一样的；第二是可回收和不可回收的界限不明，一些较为严格的分类并非为同学们所熟悉；第三是回收的可信度，常常会遇到这样的情况，被分类的垃圾在环保人员清理的时候往往是一股脑的倒在一起，根本起不了垃圾分类的效果。

It is necessary to find a new method for garbage disposal. Compared to existent methods, landfill method of garbage block has its characters, which includes classification throwing, collection and predispose of garbage that make garbage disposal classification; use of reclaimable street collection that make garbage disposal resource; shatter,dehydration and press packing of garbage street collection that make garbage disposal decrease; disinfection and classification stack that attribute to classification administer and supervise of garbage field and make garbage disposal harmlessness; recycle, compost, burning and landfill that make garbage disposal synthesis; exploitation and use of garbage field that make garbage disposal environmental protection.

与已有的垃圾处理方法比较，垃圾块体填埋法有自己的特点，以社区为单元的垃圾源头分类投放、收集和预处理，能使垃圾实现分类化处理；通过垃圾中可回收废物的回收利用，能使垃圾最大限度资源化；通过垃圾分类粉碎、脱水、压缩成块体，使垃圾有效地减量化；经过消毒、分类堆砌有助于垃圾填埋场地的分类管理和安全监控，使垃圾处理基本无害化；回收、堆肥、焚烧、填埋，使垃圾处理综合化；填埋场的复垦与开发利用，使垃圾处理环保化。

The test result shows:(1) Concentration after grind finely, multi product configuration, regrind and reconcentratipn of sulphide iron ore, and firstly recovering tin and removing sulfide ore as possible as are available metholds to improve the grade and recovery of tin concentrate, simplify technology flowsheet and reduce production cost;(2) Intensifying the recovery of single stage concentration table is the key to concentration to concentration after grind firely and improving index. The recovery of fine tin is sure to further improve index;(3) Regrind and reconcentration of ferro-sulphur ore may recovery some tin.

试验研究结果表明：(1)细磨入选，多产品结构，硫化铁矿物再磨再选，能拿早拿、能丢早丢，预先脱出硫化矿物是提高锡精矿品位和回收率，简化工艺流程，降低生产成本的有效途径；(2)强化一段摇床的回收是细磨入选，提高指标的关键，细粒锡石的回收是进一步提高指标的根本保证；(3)硫铁矿物再磨再选也可回收部分锡金属。

The utility model relates to a recoverer of vibrating drying apparatus, characterized in that the recoverer (1) is directly fixed at the body (2) and the recoverer (1) is arranged in channel (3) of tail gas of the drying equipment.

一种振动式干燥设备回收装置，回收器（1）直接固定于振动主体（2）上，且该回收器（1）布置于干燥设备的尾气流道（3）中。

The actuality of domestic packaging wastes,problems in recovery of packaging wastes,the characters of reverse logistics ,and the model of reverse logi.

论述了国内包装废弃物的现状，包装废弃物回收利用中存在的问题以及回收逆向物流特点，并就包装废弃物回收逆向物流模型的建立和模式进行探讨。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
