Product Description

Types of wastewater treatment equipment

Industrial wastewater vapor-liquid separation treatment equipment

Industrial wastewater gas-liquid separation equipment is mainly used to remove volatile pollutants from wastewater in dissolved or mixed forms. Its core process alters the system equilibrium through heating, depressurization, or gas stripping, efficiently transferring pollutants from the liquid phase to the gas phase, thus achieving the dual purpose of wastewater purification and pollutant concentration and recovery. This technology is widely applicable to the pretreatment of high-concentration organic wastewater in industries such as chemical and pharmaceutical manufacturing.

Removal Rate:	High-quality equipment should achieve a removal rate of over 99%, effectively removing pollutants such as COD and ammonia nitrogen from wastewater.
Peak Processing Capacity	The equipment must possess good load-bearing capacity to cope with fluctuations in wastewater generation during production.
COD, BOD	Record the COD and BOD concentrations of the influent, effluent, and intermediate units; calculate the removal rate; and evaluate the removal effect of organic matter.
SS	Record the SS concentrations of the influent, effluent, and sedimentation tank effluent; and evaluate the removal effect of suspended solids.
Ammonia Nitrogen, Total Nitrogen, Total Phosphorus	Record the ammonia nitrogen, total nitrogen, and total phosphorus concentrations of the influent, effluent, and biological treatment tank; and calculate the nitrogen and phosphorus removal efficiency.
Heavy Metals	Record the heavy metal concentrations of the influent and effluent to ensure compliance with discharge standards.

1.High-Salinity Wastewater Evaporation Crystallizer

For the treatment of high-salinity wastewater, evaporation and crystallization technology is key to achieving zero emissions and resource recovery. Common evaporation crystallizers include:

Forced Circulation Evaporator:

MVR Evaporator: 

Triple-Effect Evaporation Crystallizer:

This uses a pump's powerful circulation action to force wastewater through the heating tubes at a high velocity, making it suitable for treating high-viscosity, scaling-prone wastewater.

This utilizes mechanical vapor recompression technology to compress and heat secondary steam, which serves as a heating source, significantly improving thermal energy efficiency.

This utilizes multiple-effect evaporation technology to utilize secondary steam generated in the first effect as a heat source in the next effect, reducing steam consumption.

2.Biological Wastewater Treatment Equipment

Aerobic Biological Treatment Equipment:

Anaerobic Biological Treatment Equipment:

Aeration Tanks: Aeration devices are used to oxygenate the tank, allowing microorganisms in the activated sludge to rapidly multiply and degrade organic pollutants.
Biological Contact Oxidation Tanks: Microorganisms attach to the surface of the filler to form a biofilm. As wastewater flows through the biofilm, organic pollutants are broken down.
Membrane Bioreactors (MBRs): Combine membrane separation technology with biological treatment technology to achieve efficient sludge-water separation, resulting in excellent effluent quality.

UASB Reactors: Wastewater rises from the bottom of the reactor, where it comes into contact with anaerobic granular sludge, degrading pollutants and producing biogas.

IC Reactors: An internal circulation system increases the agitation intensity of the water flow and biogas, further improving sludge concentration and reaction efficiency.

3.Chemical Treatment Wastewater Treatment Equipment

Neutralization Reactor:

Sedimentation Tanks:

Coagulation Reactor:

Function: Adjusts wastewater pH to an appropriate range by adding acid/base regulators.

Features: Equipped with an automatic dosing system and an online pH monitor for precise control of acid/base dosage.

Ozone Oxidation Equipment: Utilizes ozone's strong oxidizing properties to rapidly degrade non-biodegradable organic pollutants while also providing sterilization and decolorization.
Fenton Reactor: Efficiently degrades persistent organic pollutants through the generation of hydroxyl radicals from hydrogen peroxide and ferrous salts.

Function: By adding a coagulant, fine suspended particles and colloids in the wastewater are aggregated into large flocs, facilitating subsequent sedimentation or filtration.

4.Wastewater Treatment Equipment for Advanced Treatment and Reuse

Filtration Equipment:

Desalination Equipment:

Quartz Sand Filter: Removes suspended matter and particulate matter from water.

Activated Carbon Filter: Removes odor, color, organic matter, and heavy metal ions from water.

Precision Filter: Removes tiny particles and colloids from water, protecting subsequent membrane separation equipment.

Reverse Osmosis (RO) Equipment: Utilizing the selective permeability of a semipermeable membrane, water is forced through the membrane under high pressure, while impurities such as salt are retained. Desalination rates can exceed 99%.

Electrodialysis Equipment: Using an electric field, ions in water migrate toward corresponding electrodes, separating salt from water through an ion exchange membrane.

Selection Recommendations

1.Wastewater Quality and Quantity: Select the appropriate treatment process and equipment based on wastewater indicators such as COD, BOD, salinity, pH, and suspended solids concentration.
2.Treatment Objective: If wastewater reuse is required, advanced treatment equipment (such as MBR or reverse osmosis equipment) is required. If compliance with discharge standards is required, equipment with appropriate treatment accuracy should be selected in accordance with local environmental standards.
3.Economics and Stability: While ensuring treatment effectiveness, prioritize equipment with low operating costs, easy maintenance, and a low failure rate.
4.Intelligence and Automation: Selecting equipment equipped with online monitoring and automatic control features can reduce manual operations and improve treatment efficiency and stability.
