Product Description

 

Scope of application

Petrochemical industry, natural gas extraction and processing, industrial parks, landfills, sewage treatment plants.

Technical Type	Working Principle	Advantages and Disadvantages	Application Scenarios
Multi-Effect Evaporation (MEE)	Utilizes the secondary steam generated by the previous-effect evaporator as the heat source for the next effect, connecting multiple evaporators (2-6 effects) in series to improve thermal energy utilization.	Low energy consumption (about 30-50 kg steam/ton water), moderate equipment investment; large floor space required, suitable for stable heat sources (e.g., power plant steam).	Large-scale leachate treatment (>100 tons/day) in scenarios with steam resources.
Mechanical Vapor Recompression (MVR)	Increases the temperature and pressure of secondary steam through a compressor, recycling it as a heat source with almost no external steam consumption.	Low energy consumption (about 80-120 kWh/ton water), small footprint, high automation; 30%-50% higher initial investment than MEE.	Medium-scale treatment (20-200 tons/day) in scenarios with sufficient power but no steam resources.
Falling Film Evaporation	Wastewater flows in a film-like manner along the inner wall of heating tubes, evaporated by external heating, featuring high heat transfer efficiency.	High heat transfer coefficient (about 1,500-3,000 W/M2·K), low energy consumption; prone to scaling, requiring regular cleaning.	Leachate with fewer suspended solids or used as a pretreatment unit.
Plate Evaporation	Employs plate heat exchangers as evaporation elements, with high heat transfer efficiency and compact structure.	Small footprint, easy to clean; high corrosion resistance required, suitable for low-salinity wastewater.	Pretreatment or small-scale devices.

 

 

How it works

I. Definition based on equipment functions and application scenarios
1.Core functions
The main role of leachate wastewater evaporation devices is to treat high - concentration organic wastewater (such as landfill leachate, industrial wastewater, etc.) through evaporation technologies (such as multi - effect evaporation, MVR mechanical vapor recompression, etc.). Through evaporation and concentration, the amount of wastewater is reduced, reusable clean water is separated out or the concentration of pollutants is reduced, so as to meet the discharge standards or achieve the purpose of recycling.
2.Typical application scenarios
1.Waste treatment field: Treat leachate generated from domestic waste landfills and incineration plants. This type of wastewater contains high - concentration organic matter, ammonia nitrogen, heavy metals, etc., with complex components, and requires deep treatment through evaporation devices.
2.Industrial wastewater treatment: For high - salt wastewater and high - concentration organic wastewater generated in industries such as coal chemical industry, petrochemical industry, and pharmaceutical industry, evaporation devices can be used as an end - treatment process to achieve wastewater reduction and resource utilization.
3.Hazardous waste treatment field: Treat leachate generated during the incineration or landfilling of hazardous waste to meet strict environmental protection discharge standards.

II. Definition based on technical principles and equipment classification
1.Type of technology involved
It belongs to evaporation concentration technology equipment. Its technical principle is based on the physical process of liquid evaporation - condensation. By heating, the water in the wastewater is evaporated, and pollutants are left in the concentrated solution, thus achieving water purification. Common types of evaporation devices include:
1.Multi - effect evaporation (MEE) devices
2.Mechanical vapor recompression (MVR) evaporation devices
3.Falling - film evaporation devices
4.Plate - type evaporation devices, etc.
2.Equipment classification and attribution
In the environmental protection equipment system, it can be classified as:
1.Wastewater treatment equipment: Directly serving the wastewater purification process, it belongs to end - treatment or deep - treatment equipment.
2.Resource utilization equipment: In some scenarios, the condensed water generated by evaporation can be reused in the production process to realize the circular utilization of water resources, so it also belongs to one type of resource recovery equipment.

III. Association and differences from other equipment

1.Relationship with leachate treatment systems
Leachate wastewater evaporation devices are usually the core unit in leachate treatment systems and need to be used in conjunction with pre - treatment equipment (such as equalization tanks, filtration devices) and post - treatment equipment (such as membrane treatment, biochemical treatment) to form a complete treatment process.
2.Differences from general wastewater treatment equipment
1.High pertinence: Designed for high - concentration, hardly degradable wastewater such as leachate, with higher treatment load and technical requirements than ordinary domestic sewage treatment equipment.
2.High energy consumption: The evaporation process requires the consumption of heat energy or electric energy. Therefore, the equipment is usually equipped with energy - saving designs (such as MVR technology to recover steam energy) to reduce operating costs.

 

IV. Attribution to industry standards and specifications
In industry classification, leachate wastewater evaporation devices can refer to the following standards:

·Classification of environmental protection equipment: According to the "Classification and Naming of Environmental Protection Equipment" (HJ/T 11 - 1996), it belongs to the subclass of "physical and chemical treatment equipment" among "wastewater treatment equipment".
·Attributes of special equipment: If the equipment involves high - pressure steam or pressure vessels (such as in high - temperature evaporation scenarios), it needs to comply with the relevant regulations in the "Regulations on the Safety Supervision of Special Equipment" and belongs to the management category of pressure vessel equipment.

V. Typical application cases
Case 1: Landfill leachate treatment
A 500 - ton - per - day landfill adopts the "pre - treatment + MVR evaporation" process. The COD of the condensed water is < 50 mg/L and is reused for greening; the concentrated solution is landfilled after solidification.
Case 2: Coal chemical industry leachate treatment
A coal chemical enterprise adopts the "multi - effect evaporation (3 - effect) + crystallization" process to treat high - salt leachate (TDS > 10,000 mg/L). The condensed water is reused in the circulating water system, and the concentrated solution is crystallized to obtain industrial salt.

 

VI. Trends in technology development

·Energy - saving: The MVR technology has gradually become the mainstream due to its low energy consumption. Combined with photovoltaic power, the operating cost can be further reduced.
·Intelligentization: Optimize evaporation parameters (such as temperature, pressure) through AI algorithms to achieve adaptive control and reduce manual intervention.
·Zero - discharge integration: The combination of evaporation and membrane technology (such as RO) to achieve "zero discharge" of wastewater, but the cost and feasibility need to be comprehensively considered.
