Influence of the concentration of Cr in the leachate and quantity of Pb(CH3COO)2 of Pb(NO3)2 on the reaction of synthesizing yellow chrome was also studied. Finally, according to the criterion and standard method in GB3184-82, some yellow chrome synthesized in the experiments was sampled and the concentration of PbCrO4 in these samples was determined. The following conclusion can be drawn from these experiments.

根据中华人民共和国国家标准GB3184-82中的规定铅铬黄颜料的技术质量指标和检测方法，测定了铬黄样品中铬酸铅含量的厂迄回【、矾士牢位论父泅仰yW盯皿'S川mS达标情况，结论如下：门）反应中重铬酸盐的浓度并不需要达到前人所提出的150～2509·L'的范围，在一定条件下低于此浓度时对铬黄生成反应并无不利影响。

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。

Regional development occupies large land, develops lots of contents, relates to multifields including industry, construction, business and civicism, so it is necessary to identify its influence on nature environment such as air, groundwater quality, surface water quality and hydrological condition, sound, soil, plants, topographty and social environment such as population, traffic, economic structure. The countermeasures of carring through circular economy, controlling pollution sources, planning industrial structure scientifically, distributing reasonably, implementing cleaner production and total quantity control should be taken to promote regional sustainable development.

区域开发具有较大的不确定性，并且占地面积大、开发的内容广、性质复杂、建设周期长，通常的区域开发都有可能涉及到工业、城建、商业、人居、市政等多个领域的开发活动，所以区域开发必须结合区域开发的特征，准确识别其可能对区域内及其周边的空气环境、地下水质量、地表水水质及水文条件、声环境、土壤、植被、地形地貌等自然环境和人口、交通、经济结构等社会环境等产生的影响，并采取发展循环经济，减少污染生成的源头控制措施；科学规划产业结构，合理布局的预防性措施；源内达标、区域集中控制的污染治理措施；实施清洁生产、总量控制，推进区域环境与经济的持续发展。

And the existing methods to decontaminate the waste water were with mechanism equipment or by the biochemical engineering, which were both high cost and difficult to reach the national standard.

现有的污水工程处理方法，单靠机械或生化工程设施来治理污水，很难使废水达标排放或处理成本十分昂贵，而且需要投入大笔的工程资金。

Deliquescent oxygen reduced with longer balance time and greater difference from standard occurred. Before balancing,deliquescent oxygen was close to saturation. The results under 20 ℃ met the standard.

结果： 以蒸馏水和纯净水作为稀释水水源，其BOD5都小于0.2 mg／L，均达到标准；平衡时间增长，当日溶解氧量趋于降低，与标准值的差值也逐渐增大，未经平衡的溶解氧量接近饱和；20 ℃时的测定结果达标。

Result: when distilled water and purified water was used as diluting water, no obvious difference of bod5 was found between them, and both the results reached the standard （ below 0.2 mg/l）. deliquescent oxygen reduced with longer balance time and greater difference from standard occurred. before balancing,deliquescent oxygen was close to saturation. the results under 20 ℃ met the standard.

结果： 以蒸馏水和纯净水作为稀释水水源，其bod5都小于0.2 mg／l，均达到标准；平衡时间增长，当日溶解氧量趋于降低，与标准值的差值也逐渐增大，未经平衡的溶解氧量接近饱和；20 ℃时的测定结果达标。

5Hours, the aeration time of deposal of nitrogen is 10minutes, the settlement time is 1hour, and finally draw.
