What should pay attention to the application of garbage leachate treatment equipment Work Author:? Leachate treatment equipment for landfill must have a system, we need to understand some of its applications during long-term use in the process of landfill leachate treatment equipment Precautions to standardize the operation and maintenance of equipment. Let's take a look at the editor below to understand what should be paid attention to when using landfill leachate treatment equipment? Seasonal changes in water volume and water quality The water volume and quality of landfill leachate treatment vary with the seasons. Generally speaking, the rainy season is from May to October, and the dry season is from November to April. The amount of water in the rainy and dry seasons has almost doubled, and the concentration of pollutants in the rainy season is much higher than that in the dry season. Different water quantity and water quality change response plans should be formulated during operation. Anaerobic system If the UASB process is used in the anaerobic system of landfill leachate equipment, large water volume and water load should be avoided during operation to ensure the stability of the UASB process system. At the same time, attention should be paid to the phenomenon of water effluent and timely monitoring of anaerobic Dispose of water in time. Supplementary carbon source As the emission standard is the 'Pollution Control Standard for Domestic Waste Landfill Sites' (GB 16889-2008), the total nitrogen emission standard is less than 40mg/L. Therefore, this project has designed and operated a secondary biochemical system. According to the actual influent water volume and water quality, timely adjust the carbon source replenishment and reflux ratio to ensure that the total water output of the system meets the standard. Membrane system is running. Landfill leachate membrane system mainly includes ultrafiltration system, nanofiltration system and reverse osmosis system. According to the water quality, membrane operating pressure and other parameters, the system can be repaired and maintained in time, cleaned and maintained regularly, and the system can run stably for a long time. Safe operation The main treatment unit of the landfill leachate treatment station should be equipped with a detection and alarm device for the concentration of toxic and harmful gases (methane, hydrogen sulfide), and a warning sign should be hung. The regulating tank and anaerobic system should be equipped with methane and hydrogen sulfide. The alarm device and sludge dewatering room should be equipped with hydrogen sulfide detection and alarm devices, and related detection and alarm devices should be checked regularly.
