Abstract:

A new environmentally friendly non-phosphorus water treatment formula is developed. The formula performance is investigated through the static scale inhibition test, rotating coupon corrosion test and dynamic simulation test, respectively. The formula is applied on-site in the circulating water field of the coal chemical plant. The results prove that the treatment effect of the non-phosphorus formula can fully meet the technical requirements of the Code for Design of Industrial Recirculating Cooling Water Treatment(GB/T 50050-2017), and the sewage drainage reaches the first-level discharge standard, specified in the Integrated Wastewater Discharge Standard(GB 8978-1996).
