Introduction to Laboratory Sewage Treatment Equipment

1、 Equipment composition:

This small-scale laboratory wastewater treatment equipment mainly consists of four parts: reaction tank body, dosing system, filtration system, disinfection system, and electrical control system.

The main body of the reaction pool is mainly divided intopHRegulating tank, micro electrolysis tank, inclined tube sedimentation tank, clean water tank, ozone disinfection box.

The dosing system is mainly divided intoPACDosing systemPAMDosing system, acid dosing system, alkali dosing system.

The filtration system mainly includes transparent shell filters and their matching pump valve components.

The electronic control system includes manual and automatic control of electrical appliances in the entire processing equipment, monitoring of liquid level signals in the clean water tank, and display and control of various instruments.

2、 Process flow description:

The laboratory wastewater is collected into a collection tank, and the wastewater in the collection tank is quantitatively lifted by a lift pump to a small-scale laboratory wastewater treatment equipment,pHOnline installation in the regulating poolpHDetecting instruments, automatically adding acid and alkali based on instrument signals, andpHAdjust to neutral,Afterwards, the wastewater is passed through a micro electrolysis cell, where countless tiny primary cells are formed between iron carbon electrodes to oxidize iron and produce ferrous coagulants, which have a removal effect on metal ions and other particles with weak negative charges. Afterwards, through the inclined tube sedimentation tank, in conjunction withPACThePAMThe metal ions in the wastewater are precipitated and flocculated, and the sludge water separation is completed in the inclined tube sedimentation tank. Then, the wastewater is sequentially filtered through the filtration system, disinfection system, and deep treatment by the filtration pump to meet the discharge standards.
