The invention provides a
water quality detection concentration calculation method and
system, and relates to the field of
water quality concentration detection.The method comprises the steps that after sample injection, quantification, preset
reagent mixing, transferring and centrifugal color development are sequentially executed, photoelectric detection is continuously conducted on a target
water sample for preset times, and the
total phosphorus concentration, the
total nitrogen concentration, the COD concentration and the
ammonia nitrogen concentration for preset times are obtained; determining the actual
total phosphorus concentration of the target
water sample, and determining the actual
ammonia nitrogen concentration of the target
water sample; calculating an actual
total nitrogen concentration matrix according to the initial
total nitrogen concentration matrix and the total
nitrogen implicit
transfer matrix, and determining the actual total nitrogen concentration of the target water sample; and calculating an actual COD concentration matrix according to the initial COD concentration matrix and the COD implicit
transfer matrix, and determining the actual COD concentration of the target water sample. According to the invention, a plurality of different index detections are integrated on the same
chip, the accuracy of the detection results of the total nitrogen concentration, the COD concentration, the
total phosphorus concentration and the
ammonia nitrogen concentration is ensured, the detection time is shortened, and the detection efficiency is improved.
