The invention relates to the technical field of
wastewater treatment, and discloses a heavy
metal wastewater treatment method and
system.The method comprises the steps that the concentration, pH value, temperature and
conductivity data of heavy
metal ions are collected in real time through multiple types of sensors arranged in a
wastewater pipe network and a treatment
station, and standardized treatment is conducted; inputting the standardized data into a prediction
algorithm unit, executing multi-parameter fusion analysis, and generating a
concentration prediction result and a
processing agent dosage; the coagulation reactor and the
sedimentation tank are controlled to operate according to the prediction result, and chemical
sedimentation and concentration of the heavy
metal ions are achieved; the treated wastewater is deeply purified through adsorption,
ion exchange and filtering processes, the final discharged
water quality is obtained, the treatment efficiency is fed back, and closed-
loop optimization control is formed. The
system comprises a
data acquisition and pretreatment module, a prediction and addition control module and a reaction and purification execution module, can realize automatic and intelligent optimization control of the wastewater treatment process, and remarkably improves the
effluent standard-reaching rate and the
system stability.
