Quotation for fully automatic buried industrial sewage treatment equipment

1、 Equipment type

1. Specialized equipment

• Grille slag removerIntercept large suspended particles.

• aeration equipment(such as surface aerators and rotary brush aerators): Increase dissolved oxygen in water and promote microbial degradation.

• Sludge treatment equipment(such as sludge thickening scraper, sludge dewatering machine): deals with the sludge generated during the main treatment process.

• Membrane bioreactor (MBR)Combining biological treatment and membrane separation technology to efficiently remove organic matter and suspended solids.

2. General equipment

• pump(such as sewage pumps, sludge pumps): Transport sewage and sludge.

• fan(such as Roots blower, magnetic levitation fan): Provide the air required for aeration.

• Valves and instruments(such as electromagnetic flow meters, pH meters): Control flow and monitor water quality.

3. electrical equipment

• Motor and switchgearDrive the device to operate.

• Substation and Distribution EquipmentProvide power support.

2、 Process flow

1. preprocessing

• Remove large particle impurities and suspended solids to reduce the subsequent processing load.

• Common equipment: grating, sedimentation tank, regulating tank.

2. Main processing

• Biological treatmentUsing microorganisms to degrade organic matter (such as activated sludge process, biofilm process).

• chemical treatmentRemove heavy metals and suspended solids through precipitation by adding medication.

• physical treatmentLike air flotation to remove oil and fine particles.

3. deep processing

• Further remove recalcitrant organic matter, nitrogen and phosphorus nutrients.

• Common techniques: activated carbon adsorption, ozone oxidation, reverse osmosis.

4. sludge treatment

• Concentrate, dehydrate, dry or incinerate to reduce the volume of sludge and achieve harmless treatment.

3、 Application Fields

• Machining: Treat emulsified oily wastewater.

• petrochemicalTreatment of refinery wastewater and mixed wastewater of oil and fat suspended solids.

• Electroplating industryRemove heavy metal ions (such as chromium, nickel, copper).

• printing and dyeing industryReduce the color and organic content of wastewater.

• pharmaceutical industryDealing with high concentration and difficult to degrade wastewater.

• food processingRemove high concentrations of organic substances (such as juice wastewater).

• animal husbandryTreat aquaculture wastewater to reduce water pollution.
