Abstract

The invention relates to the technical field of wastewater treatment and particularly relates to a system for intelligently controlling dosing amount in heavy metal wastewater treatment. The system includes, in a successively connected manner, a first water quality auto-analysis device, a first flow sensor, a reaction tank, a second water quality auto-analysis device, a first electric valve and asecond flow sensor, and also includes a backflow bypass connected between the second water quality auto-analysis device and the first electric valve. The backflow bypass is successively provided witha second electric valve and a third flow sensor. The system further includes a reagent metering pump connected to the reaction tank, and an intelligent control system respectively connected to the first water quality auto-analysis device, the second water quality auto-analysis device, the flow sensor and the reagent metering pump through signals. During control of dosing amount, the system can change the dose by fluctuation of heavy metal content in the wastewater, so that on the basis of guaranteeing the effluent quality, waste of the reagent is reduced, and quantity of sludge is reduced, misjudgment rate by manual work is reduced, and high efficiency and manpower saving are achieved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a system for intelligently controlling the dosing amount in wastewater treatment containing heavy metals. Background technique [0002] In the wastewater treatment of the prior art, an online water quality detector for detecting SS, phosphate, and heavy metals is used. However, none of the online water quality detectors in the prior art can detect real-time values ​​in time, and there is a problem of time delay in the detection data. For example, the online TP and heavy metal detection in the prior art are delayed by about 1 hour. The delay of these detection data leads to the inability to immediately guide the adjustment of the dosing amount, and will lead to waste or shortage of chemicals, which in turn will lead to excess sludge or substandard water quality. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies i...
