Microbial preparation for processing transformer oil stains

The invention relates to a microbial preparation for processing transformer oil stains, and a method for removing transformer electroplating wastewater through using the preparation. The method comprises the following steps: carrying out solid-liquid separation to effectively prevent the obstruction phenomenon and apparatus damages appearing in the wastewater conveying process, removing suspensions by using a floater removal device, adding 10g of a flocculating agent to every cubic meter of wastewater, reacting for 30-40min, discharging wastewater to a microbial reaction tank, adjusting the pH value to 7-8, adding 15g of an inoculant to every cubic meter of the liquid, and standing for a weak. The method improves the water treatment capacity and the quality of treated water, reduces the running cost, and promotes standard reaching discharge.
