1, structural composition is different: waste leachate treatment DTRO process flow is simple and compact, standardized equipment sets, DTRO two-stage process set of devices integrated for pretreatment sand filter system, security filters, used for reverse osmosis separation of the membrane module, high-pressure pumps, circulating pumps, used for the cleaning of the system cleaning tanks, as well as power supply for the equipment and the control of MCC cabinets and PLC cabinets. etc.
The PT/ST membrane modules used in the STRO system have the advantages of low membrane contamination, high packing density, low salt passage rate and the ability to realize built-in standard cleaning and maintenance. At the same time STRO system has a reverse osmosis unit can be disassembled, the system is simple to install and maintain, the equipment occupies a small area and can be placed in the container mobile and so on. It is very suitable for small-scale waste leachate treatment.
2, the respective performance points are different: waste leachate treatment DTRO process process stability, simple maintenance, low energy consumption DTRO membrane module to effectively avoid membrane fouling, membrane contamination is reduced, so that the reverse osmosis membrane life extension.
The use of STRO process leachate treatment, the system operating efficiency and stability, the ammonia nitrogen removal rate of 99.2% -99.5%, the COD removal rate of more than 99.5%, the conductivity removal of 92% -95%, the effluent is not detected SS, combined with the concentrate back to the irrigation to realize the zero discharge of pollutants.
Extended information:
The nature of the leachate varies with the operating time of the landfill, which is mainly determined by the process of stabilization of waste in the landfill. This is mainly determined by the stabilization process of the waste in the landfill. The landfill stabilization process is usually divided into five stages.
These are the Initial
adjustment phase, the Transition phase, the Acid phase, the Methane fermentation phase and the Maturation phase. Maturation phase.)
Waste leachate is the sewage that leaches out of the landfill due to fermentation, rainfall, and surface and groundwater soakage during the landfill and landfill process. There are four main sources: the water contained in the garbage itself, the water produced by the garbage biochemical reaction, the reverse osmosis of underground diving and atmospheric precipitation, of which the atmospheric precipitation is concentrated, short-lived and repetitive, accounting for most of the total amount of leachate.
Leachate is a kind of high-concentration organic wastewater with complex composition, the nature of which depends on the composition of the garbage, the particle size of the garbage, the degree of compaction, the climate of the site, hydrological conditions and the time of landfilling, and other factors.
