Product Advantages of SINOKLE Landfill Leachate Treatment Equipment
SINOKLE landfill leachate treatment equipment centres on homogeneous and heterogeneous multiple catalytic oxidation technology, integrating the CDFU, CDOF proprietary processes and key technologies such as ozone microbubble generation. Tailored to the high salinity, high COD, high organic load, complex composition and poor biodegradability of landfill leachate, it shows all-round advantages over conventional equipment in technical performance, pollutant removal, operating economics and equipment adaptability. Its technical features are as follows:
Core catalytic technologies work synergistically, with industry-leading oxidation capacity
The equipment is built around homogeneous and heterogeneous multiple catalytic oxidation technology, combining the advantages of homogeneous catalysts that generate hydroxyl radicals efficiently with heterogeneous catalysts based on multiple active metal oxides, rapidly producing hydroxyl radicals, superoxide radicals and other active species. Combined with ozone microbubble generation, ozone utilisation is greatly improved and ozone oxidation performance is more than 6 times higher. The efficiency of active species generation and the oxidation capacity far exceed those of single-catalyst technologies, tackling at the root the industry pain point of poorly degradable macromolecular organics in landfill leachate.
Efficient and thorough pollutant removal, suited to complex leachate water quality
Given the high salinity, high organic load, high colour and strong odour of landfill leachate, the equipment degrades pollutants efficiently in stages: homogeneous catalysis rapidly attacks the chemical bonds of macromolecular organics, breaking them into readily degradable small molecules, while heterogeneous catalysis deeply oxidises the small-molecule intermediates through its highly porous structure, ultimately converting them into harmless substances and preventing toxic accumulation.
It also efficiently removes difficult pollutants such as dissolved oil and benzene series compounds, achieving exceptional removal of colour and odour. It overcomes the inhibition of catalytic reactions by salt ions and maintains stable oxidation activity in high-salinity conditions. COD removal rises from 42% with conventional processes to 88%, and benzene series removal reaches 98%, with strong shock resistance to fluctuations in landfill leachate quality.
Greatly improved treatment efficiency, with reaction time far below conventional equipment
Relying on CDOF proprietary process design and high-porosity microporous forming technology, the equipment provides ample reaction interfaces for catalytic reactions, extending contact time between pollutants and active species and greatly improving mass transfer efficiency. The effective reaction time of the core oxidation unit is only 15 minutes - one tenth of conventional processes - enabling rapid on-site compliant treatment of landfill leachate and solving the low efficiency and long reaction cycles of conventional equipment. Capacity reaches up to 200 m3/h, suiting leachate treatment needs of different scales.
Lower energy consumption and cost, with outstanding industrial operating economics
The efficient hydroxyl generation of homogeneous catalysis reduces oxidant dosing, while the high activity and stability of the heterogeneous catalyst further lowers the proportion of homogeneous catalyst required, cutting overall oxidant consumption by more than 50%. Ozone microbubble technology greatly improves ozone utilisation and avoids chemical waste. In addition, the heterogeneous catalyst undergoes hydrophilic modification and anti-fouling treatment, extending its service life to more than 6 years (industry average 2-3 years) with no frequent replacement. Together with fully automatic operation, this substantially reduces labour and maintenance costs, bringing overall operating cost to just one third of conventional equipment and optimising both energy and consumable costs.
Integrated skid-mounted design: small footprint and flexible deployment
The equipment uses a highly integrated, skid-mounted design with a greatly simplified process flow, occupying only one fifth of the footprint of conventional leachate treatment equipment with no large-scale civil works. Custom manufacturing is supported, with equipment parameters adjusted to actual project needs to suit on-site leachate treatment in different scenarios. Shipping and installation are convenient, enabling rapid project delivery and greatly shortening construction and commissioning cycles.
Stable, anti-fouling operation with low maintenance frequency and easy management
The heterogeneous catalyst uses hydrophilic modification and anti-fouling, anti-clogging technology, greatly reducing adsorption and scaling of leachate pollutants on the catalyst surface and preventing catalyst deactivation and equipment clogging. The synergistic catalytic system is little affected by water quality fluctuations, and the equipment operates stably at up to 50 C and 0.1 mPa. Equipped with a fully automatic control system, it runs under pressure in a fully enclosed mode, supporting remote monitoring and unattended operation and greatly reducing manual operation and maintenance frequency.
Green and eco-friendly with no secondary pollution, meeting stringent discharge standards
There is no metal leaching throughout the process, and effluent meets the heavy metal discharge requirements of the Integrated Wastewater Discharge Standard (GB 8978-1996). A full-volume, membrane-free process is used, producing no concentrate and greatly reducing sludge volume, preventing secondary pollution at the source. Pressurised fully enclosed operation means zero leakage and no odour diffusion - a green, eco-friendly treatment process suited to the ecological requirements of waste treatment sites.
Mature technology with broad adaptability, with application results proven in practice
The equipment incorporates multiple patented technologies, with core processes internationally leading and unique in China. It provides tailored solutions not only for landfill leachate and press liquid but also for pre-treatment and advanced treatment of refractory wastewater in the pharmaceutical, metallurgical and oilfield industries, as well as upgrades at wastewater treatment plants. Multiple landfill leachate treatment projects are already running successfully with stable compliance and strong owner recognition, giving reliable assurance of technical maturity and practical performance.
Summary: SINOKLE landfill leachate treatment equipment centres on homogeneous and heterogeneous multiple catalytic oxidation technology and integrates multiple proprietary processes and key technologies to deliver a customised solution for the complex water quality of landfill leachate. The equipment performs excellently in oxidation capacity, pollutant removal and treatment efficiency, while featuring low operating cost, a small footprint, flexible deployment and stable, easily managed operation. It is green and eco-friendly with no secondary pollution throughout, with mature core processes and broad adaptability. With treatment results proven stable and compliant in real projects, it is an excellent choice for landfill leachate treatment.
