Abstract:

In this paper, the cleaning action, efficiency and feasibility of deep purification of biological treatmental water to petrochemical wastewater with the method of land treatment were discussed and studied. The results show that purification effect of land treatment was evident, the quality of regenerated water achieved anticipated standard, the application of this water to make-up the cooling water circulating system have good environmental and economic effects.

Key words: land treatment, petrochemical wastewater, recycling of wastewater, circulating cooling system
