ZCJ—961工业污水处理剂的应用 总被引:1,自引:0,他引:1
甘敏 《石油化工环境保护》2000,23(4):14-16
气体脱硫装置在停工处理过程中,通常采用传统的失蒸汽吹扫,后用热水冲洗的方法,但是效果总是不理想。为确保停工过程中,各设备冲洗干净,避免发生硫化氢中毒事故,防止出现硫化亚铁自燃等问题,在2000年2月洛阳石化总厂二套催化裂化装置第3周期停工过程中,试用ZCJ-961含硫、氨氮工业污水处理剂对气体脱硫装置进行化学清洗,取得了令人满意的效果。 相似文献

Wastewater irrigation is an environmentally sound wastewater disposal practice, but sewage is more saline than the supplied fresh water and the salts are recycled together with the water. Salts have negative environmental effects on crops, soils, and groundwater. There are no inexpensive ways to remove the salts once they enter sewage, and the prevention of sewage salt enrichment is the most immediately available solution. The body of initiatives presently structured by the Ministry of the Environment of Israel are herein described, with the aim to contribute to the search for a long-term solution of salinity problems in arid countries. The new initiatives are based on: (1) search for new technologies to reduce salt consumption and discharge into sewage; (2) different technologies to cope with different situations; (3) raising the awareness of the public and industry on the environmental implications of salinity pollution; and (4) an elastic legal approach expressed through new state-of-the-art regulations. The main contributor to the salinity of sewage in Israel is the watersoftening process followed by the meat koshering process. Some of the adopted technical solutions are: the discharge of the brine into the sea, the substitution of sodium by potassium salts in the ion-exchangers, the construction of centralized systems for the supply of soft water in industrial areas, the precipitation of Ca and Mg in the effluents from ion-exchangers and recycling of the NaCI solution, a reduction of the discharge of salts by the meat koshering process, and new membrane technology for salt recovery. 相似文献

Specific industrial processes and its waste characteristics should be known for proper management and control of the wastes produced from industries. Some industrial processes and waste characteristics are introduced to explain how to deal with the wastes for waste characterization. Evaluation methods of biodegradability of industrial wastewater were introduced in order for environmental engineers to be able to decide the proper treatment method of the industrial wastewaters. Industrial processes and characterization discussed in this section might be useful for the selection of suitable methods to prevent pollutant discharge from industrial processes. 相似文献

Despite its strong advantages in resource, technology and human resource, China's Northeast Industrial Area is also experiencing problems of unreasonable industrial structure, environmental pollution, and the degradation of ecological condition, etc., which prevent this area from achieving a sustainable devel- opment. Through analyzing the resource problem, the present paper proposed a strategy of circular economy for the prosperity of this are, discussed the theories of circular economy and resource recycling, and finally concluded that improving resource productivity is at the core of circular economy. 相似文献

Here we show that heavy metal geoaccumulation is apparent in the Tinto and Odiel estuary and, at a lower magnitude, in off-shore
sediments. Values above probable effects level (PEL) are recorded for As, Cu, Hg, Pb and Zn in the Tinto and Odiel estuary,
for As and Hg in the associated off-shore sediments and for As in the Guadiana River. Significant correlations were found
between total organic carbon (TOC) and Cr, Cu, Ni and Zn in the Tinto and Odiel estuary, and Cr, Cu, Ni, Pb, Hg and As in
the Guadiana River. PCA analysis differentiated the three studied locations. 相似文献
