Sinopec News Network reported on April 26 that after half a month of trial operation, the rainwater reuse facility of Zhongke Refining & Chemical Co.
recovered 33,000 tons of rainwater in total.
The operation is stable and good.
It is estimated that more than 800,000 tons of rainwater can be reused annually.
Zhongke Refining & Chemical is located in the east island of Zhanjiang, Guangdong.
It has a subtropical climate with sufficient rainfall throughout the year, which can be converted into fresh water resources for production.
Since the beginning of this year, Zhongke Refinery Co.
has comprehensively coordinated and implemented fine management, put the rainwater reuse facilities on the agenda, strictly controlled the sewage and rainwater line discharge indicators of upstream installations, and adjusted the dosage of chemicals in time through real-time monitoring and carried out biochemical activities.
System air supply optimization, etc.
, continuously improve the processing capacity and processing speed of purified water, minimize the phenomenon of rainwater carrying oil, and ensure the stable operation of the sewage treatment device.
On April 10, the installation technicians added a submerged pump in the rainwater recovery tank to reduce the rainwater recovery level from 2.
6 meters to less than 0.
5 meters, optimize rainwater recovery conditions, and change the condition that only heavy rains in the early stage can be recovered.
The submerged pump transports part of the up-to-standard rainwater to the low-concentration sewage treatment tank for supplementary water treatment in the circulating water field, and the other part to the tank truck in the plant for daily watering and road sweeping to further improve rainwater utilization.
