Zhongyuan Petrochemical's ethylene plant boiler water pre-treatment system has two grit filters with a backwash volume of 450 cubic meters per day. During the backwash, this part of the water is drained in vain, wasting water resources. In this project, the backwash water of the sand filter is moderately treated and recycled to the circulating cooling water system as supplementary water for the circulating water. An integrated automatic water purifier is used to remove the suspended solids in the backwash water after the coagulation, precipitation and filtration processes. , turbidity, COD to meet the water quality requirements of circulating water make-up water. The project investment of 980,000 yuan was completed and put into use at the end of June 2007. It has been in operation for more than one year. The results show that the sand filter backwash water is treated by an integrated water purifier, which can meet the requirement of recirculating water and water purifiers. Stability, according to the current recycling capacity calculation, annual sewage reuse 144KT, according to water resource fee 4.0 yuan / cubic meter, one year direct economic benefits of 576,000 yuan. The sand filter backwashing water reuse project greatly reduces the enterprise's water intake, reduces the sewage discharge, saves the sewage charges, and also brings good economic benefits to the enterprise.
The sand filter backwash water recycling project of Zhongyuan Petrochemical's water-saving and emission reduction project has achieved good economic benefits after one year of operation.
