Where is the best DTRO membrane when treating landfill leachate?


  Landfill leachate is one of the more difficult wastewater to treat. In recent years, with the improvement of related treatment demand, the market of landfill leachate treatment has a considerable growth space。

  As we all know, the main methods of domestic waste treatment are incineration, composting, mechanical treatment and landfill。A large amount of landfill leachate will be produced in the process of garbage stacking, transfer, extrusion, transportation, burial or incineration。The content of landfill leachate is affected by many factors, such as the composition of garbage, landfill years, climatic conditions and landfill design。The characteristics of landfill leachate water quality can be summarized as follows:

  1, many types of pollutants, complex composition, high concentration。Most of the organic compounds in the landfill leachate are difficult to biodegrade, such as phenols, heterocyclic, heterocyclic aromatic and polycyclic aromatic compounds, accounting for more than 70% of the organic components in the leachate.High concentration of organic matter, COD and BOD5 high concentration。

  2, water quality, water quantity changes complex。The composition and yield of landfill leachate also change with different hydroclimatic conditions, geological conditions, geographical location, structural mode and landfill time。Moreover, the biodegradability decreased gradually with the increase of landfill age。

  3. Imbalance of nutrition ratio。The content of ammonia nitrogen in leachate is high, the C/N value is often misadjusted, and p is lacking, and the proportion of micronutrients can not meet the requirements of water treatment。

Landfill leachate treatment

  From the above description, we all know that after untreated landfill leachate flows through the surface or penetrates into groundwater, it will destroy the ecological balance of surrounding soil and cause serious secondary pollution to soil or water。In order to solve this processing dilemma, DTRO membrane technology came into being。DTRO membranes are specially designed for the treatment of difficult wastewater membranes with the following advantages in the treatment of landfill leachate:

  1, mature process, stable and reliable, high treatment efficiency, stable effluent water quality, compact structure, easy to maintain and manage。

  2. DTRO membrane has strong anti-fouling and blockage, effluent water quality is up to standard, and system operation cost is low。

  3, the use of DTRO dish tube reverse osmosis membrane, the system is reliable, can withstand high operating pressure, so that the concentration rate is greatly improved。

  4, disc tube reverse osmosis DTRO membrane elements can be operated under the conditions of 40 to 160bar, high operating pressure will make the concentrated liquid into the membrane, to achieve high concentration, reduce the concentration of water。

  5, DTRO membrane is a form of reverse osmosis, is specially used to treat high concentration of sewage membrane components, even in the case of high turbidity, high COD, high SDI, high salt, can also be economically effective and stable operation。

  DTRO membranes are used in addition toLandfill leachate treatmentIn addition, it also has important applications in the fields of high difficulty organic wastewater treatment, high salt content wastewater treatment, high difficulty chemical wastewater treatment, high difficulty metallurgical wastewater treatment, and high difficulty electroplating wastewater treatment。
