Technical Field
The utility model relates to a landfill leachate handles the field, especially relates to an extract humic acid's extraction element from landfill leachate.
Background
At present, the landfill leachate is treated by a treatment method combining biochemical treatment and membrane treatment, but the landfill leachate is treated by a concentrated solution. The concentrated solution of the landfill leachate has the following characteristics: (1) chemical Oxygen Demand (COD) is high and difficult to degrade; (2) the biodegradability is poor, organic matters in the concentrated solution of the landfill leachate are difficult to degrade, and a nutrient source is difficult to provide for microorganisms; (3) has stronger odor. Therefore, the concentrated solution of landfill leachate needs to be further treated to avoid environmental pollution.
At present, the treatment or solution of the concentrated solution of the landfill leachate at home and abroad has two general methods:
Firstly, directly recharging the concentrated solution of the landfill leachate to a landfill. When the method is adopted, the salinity and the conductivity of the leachate of the refuse landfill are obviously increased, the refuse landfill is seriously polluted, and the treatment effect is not ideal.
And secondly, collecting the concentrated solution of the landfill leachate, and evaporating the concentrated solution by a mechanical compression evaporation process. When the method is adopted, the removal effect on ammonia nitrogen and total nitrogen in the concentrated solution of the landfill leachate is very little, the ammonia nitrogen and the total nitrogen in the concentrated solution of the treated landfill leachate still cause environmental pollution, and the treatment effect is not ideal.
Further research shows that almost all organic matters in the effluent of biological treatment are humic acid which is extremely difficult to degrade and is the main reason for difficult treatment of leachate, and the humic acid has a certain positive effect on the growth of plants, but the leachate simultaneously contains toxic substances such as inorganic salts, heavy metals, toxic organic matters and the like, so that the leachate can inhibit the plants after being directly applied for a long time and even cause the death of the plants. The humic acid in the fertilizer needs to be treated so as to be applied to industry and agriculture.
