Calcium enters the printing and dyeing wastewater treatment system in the form of calcium hydroxide as a pH regulator.The paper takes a printing and dyeing wastewater treatment plant in Zhejiang province as an example,and builds a full set of simulated reactors in the same proportion on the basis of its mature process.Through Biolog microplate technology to study the effects of 130 mg/L,250 mg/L of calcium and 500 mg/L on the utilization of microbial carbon sources in aerobic pools,it was found that the utilization of carboxylic acid but the utilization of other carbon sources decreased.
