Analysis of the important position of deodorant in the process of treating the foul odor of garbage infiltration liquid
Author: Want source: http://fatheroye.com date: 2019-12-04 Clicks:
At present, the main anaerobic biological treatment processes include aerated stabilization ponds, traditional activated sludge processes, and biofilm processes. The anaerobic method includes anaerobic sludge bed, anaerobic biological filter, mixing reactor and anaerobic pond, etc. It has the advantages of low energy consumption, simple operation, low investment and operating costs.
In the process of treating garbage, more common methods include incineration, landfill, and so on. Because landfilling is beneficial to management and transportation, and the cost of waste disposal in this way is relatively low, landfilling has become one of the main methods of waste disposal. However, during the landfill process, leachate will be generated. Leachate is a high-concentration organic liquid, which will cause more serious pollution to the soil under the landfill and the surrounding environment, and it will have a long pollution. duration.
The deodorant uses plant extraction technology to extract effective ingredients from the roots, stems, leaves and flowers and fruits of various plants. It generates forces under the action of rays, improves the activity of plant liquids, and can rapidly polymerize with various harmful and odorous molecules. , Chemical reaction such as substitution, replacement, adsorption, etc., the product is neutral, and it is an environmentally friendly product that effectively removes exhaust gas, odor and odor.

The high concentration of ammonia nitrogen in the leachate will have a strong inhibitory effect on the activity of microorganisms. Therefore, the pretreatment of the leachate to remove a part of the ammonia nitrogen is of great significance for the smooth progress of subsequent biological treatment. At present, the researches on the pretreatment of leachate have the advantages of free air pretreatment and lime pretreatment, which are effective. In addition, there are chemical precipitation and adsorption methods to remove ammonia nitrogen, which have achieved different degrees of removal effect.
In the northern area, the components of garbage are mainly inorganic, and the moisture content of the garbage itself is relatively low. The generation of leachate mainly comes from precipitation. The yield and concentration of leachate are greatly affected by seasonal changes. A commonly used method is to set up a leachate adjustment tank, which increases the processing capacity during the rainy season, and reduces the processing capacity and saves energy consumption during the dry season through natural evaporation and leachate recharge. Since the leachate mainly comes from rainfall, its organic matter concentration is low.
At the same time, the carbon dioxide generated when the garbage is degraded makes the leachate appear acidic, thereby further destroying the carbonate in the garbage and causing a dissolution reaction in the finance therein. Because there are relatively many water quality components that affect the leachate, the pollution concentration and types of pollution in the leachate are also diversified. Therefore, the corresponding treatment process should be adopted for the actual situation of the leachate.
