Problems solved by technology

The disadvantages are: when the dosage is large, it needs to be equipped with flocculant crushing equipment; when the dosage is small, it is difficult to adjust and control the dosage; the mixing uniformity of the agent and water is poor
The disadvantages are: the equipment is complex and occupies a large area; the equipment is easily damaged by corrosion; when the dosage changes suddenly, the adjustment process is longer

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A method for adding medicine to a high-level tank, comprising the following steps: adding medicine into a high-level medicine-dosing metering box 1 through a liquid inlet pipe 3, setting the high and low liquid levels of the high-level medicine-dosing metering box 1, and controlling the amount of the medicine added to be at the high or low level. between the levels; establish a comparison table between the liquid level of the metering tank and the discharge flow rate, and calculate the discharge volume V per unit time with the participation of the liquid inlet process according to the comparison table; compare the discharge volume V per unit time with the expected discharge volume per unit time V' is compared, and according to the comparison result, the action of the liquid inlet valve 2 and the liquid discharge valve 5 is further contr...

Abstract

The invention discloses a method for intelligently adding a chemical agent in a sewage treatment or beneficiation process. According to the method, the opening time of a drain valve is controlled by change of the flow velocity of a drain pipe under different liquid level states of a chemical agent adding box, thus, the chemical agent adding amount is controlled accurately, and purposes of saving the chemical agent and improving the quality of the product are achieved.

Description

technical field [0001] The invention belongs to the field of flotation technology and sewage treatment, in particular to a method and system for adding chemicals for flotation and sewage treatment. Background technique [0002] There are many chemical dosing needs in the flotation process and sewage treatment process. For example, the sewage treatment process reaction flocculation tank needs to add NaOH solution, polyaluminum chloride (flocculant PAC), polyacrylamide (coagulant PAM), polymeric sulfuric acid according to the PH value of the wastewater, the concentration of suspended solids and other indicators and the proportion of water volume. Iron (flocculant PFS), iron-based active agents, sodium sulfide and other agents; foaming agents, flocculants, regulators, etc. need to be added in the flotation process; extraction agents, matrix improvers for extraction, and brighteners used in hydrometallurgical processes , Dispersants, etc. Too much addition will cause waste of ...
