排放

The feasibility analysis of lead chrome yellow production technology showed that the concentration of total lead in the wastewater was 0.018 mg/L and the concentration of chrome was 4.160×10^(-8) nig/L, which both accorded with the discharge standards.

结果］铅铬黄生产工艺的可行性分析表明，废水中的总铅浓度为0.018 mg/L，铬的浓度为4.160×10^(-8) mg/L，均符合排放标准。

The experimental result shows that, when 200～400 g/t hydroxylapatite adsorbent is used and the stirring time is longer than 60 minutes at normal temperature, the mass density of Pb 2+ in chrome yellow wastewater is reduced to lower than 0.5 mg/L, which comes up to the standard of industrial drain water (1.0 mg/L).

羟基磷灰石吸附剂对铬黄废水中Pb2 +吸附的间歇实验结果表明：当每吨废水中吸附剂用量为 2 0 0～ 4 0 0g时，常温搅拌 6 0min后，在弱酸性或中性废水中，铅离子质量浓度由2 。74mg/L降至 0 。5mg/L以下，完全符合GB8978- 1996工业废水排放标准 1.0mg/L。

After the wastewater was treated by using lead chrome yellow production technology in fact, the concentration of hexavalent chromium was 0.361 nig/L, pH value was 6.24, the concentration of total chromium was 0.963 mg/L and CODer was 67.200 mg/L. The standard exponents of all indices were all teas than 1, so the standard-attainment discharge could be realized.

采用铅铬黄生产工艺实际治理污水后，6价铬浓度为0.361 mg/L、pH值为6.24，总铬浓度为0.963 mg/L，CODcr为67.200 mg/L，各项指标标准指数均小于1，可以实现达标排放。

Circular economy is an important measure of changing economical growth model and strengthening environmental protection,as well as an effective way of adjusting industrial structure.

1循环经济的产生背景、基本概念、基本原则1.1循环经济的产生背景我国是一个人口密度大、人均资源匮乏的国家，生态环境相当脆弱。目前我国仍是"高投入、高消耗、高排放、不协调、难循环、低效率"的粗放型经济增长方式。

They would jeer whenever they saw one of those alien visitors in their clapped-out cars that would jerk to a halt in the market place and issue copious amounts of soot and smoke in the process.

那些外来的观光客乘着陈旧的老爷车来到市场内猛然刹停，这期间排放了大量的烟尘废气。当地人只要与之一照面，就会加以冷嘲热讽，一个也不会放过。

Exhaust wastes:3 times filtration (special filtrate wick, prevent fire cotton, Stainless steel), so that it's cleanlily and keep circumstance.

粉尘尾气排放：特制进口滤芯、阻燃过滤棉及不锈钢三重过滤，既干净又环保

Conversely, when the circle to the right to regulate for clockwise rotation, the position of lower pressure to discharge pressure and the back seat will be higher.

反之，当使调节圈向右作顺时针方向旋转时，其位置降低，排放压力和回座压力都将有所升高。

During the experiment the paper observed that temperature of water close-by orifice decrease , water froze and the ice layer continually gain in by a period of continued drain time.

本文在实验过程中观察到经过一段持续的排放时间后，近管口水域的温度降低，出现水域冻结并冰层不断增长状况。

The breakthrough came after the lander spent days vibrating a screen over its onboard Thermal Evolved Gas Analyzer in hopes that the clumpy soil would break loose and fall into the onboard ovens.

在此之前，"凤凰号"花费了几天的时间震动热与排放气体分析仪上的遮盖物，希望能土块能松散开来掉入携带的高温炉中。

Coal combustion in power plant is a major source of NOx.

火电厂燃煤产生的NOx是排放的主要来源。

The split between the two groups can hardly be papered over.
