Electroplating wastewater post-treatment system The types and properties are very complex, and the purpose and requirements of processing are also different. Therefore, it is often necessary to combine several processing methods (or unit technology) and reasonably configure their primary and secondary relations and sequence to form an organic whole, so as to achieve the most effective and economical processing tasks. This kind of unit process is reasonably combined into a whole, which is called wastewater treatment system. The graphical representation of the processing system is called processing system diagram or process flow diagram.

Wastewater treatment systems generally consist of several treatment series. A processing series is a series of one or more methods used to complete a specific processing goal. Treatment targets can be classified into various categories. Wastewater treatment targets are usually determined according to the particle size and properties of the removed substances (called particle size spectrum). Manufacturer of electroplating wastewater treatment equipment According to this treatment target, including sludge treatment, the mine wastewater treatment series can be divided into the following four categories:

(1) Granular material removal series. Methods include screening method, gravity separation method, etc.

(2) Suspended particle and colloid removal series. The methods include concentration, clarification, coagulation and sedimentation.

(3) Dissolved material removal series. There are many treatment methods, including chemical precipitation, adsorption, ion exchange, membrane separation, extraction, etc.

(4) Sludge treatment series. The methods include concentration, dehydration (filtration), drying, etc.
