Abstract

A modularized non-exhaust landfill leachate treatment system and treatment method, the treatment system includes: a temporary storage pool, a treatment pool, and an emergency pool, wherein a plurality of modular planting boxes are evenly arranged in the treatment pool, and each treatment pool The same number of first plants are planted in the boxes. The first plants in each planting box are plants of the same age. The treatment pool includes N first plants of different ages. The number of first plants of different ages is roughly equal. The age of the first plant is arranged, and further, the planting box also contains the second plant; the treatment system disclosed in the present invention is economical and low-cost, has good treatment effect, is adaptable to various weather environments, has stable treatment capacity, and the treated leachate Internal circulation, without any external emissions. The treatment method is carried out by using the treatment system, and the first plant of the highest age is replaced with the first plant of the youngest age every year, so that a relatively stable treatment capacity can be maintained, so that it does not change greatly with time.

Description

technical field [0001] The invention relates to the field of landfill leachate treatment, in particular to a modularized landfill leachate treatment system and a treatment method without external discharge. Background technique [0002] At present, the mainstream landfill leachate treatment process at home and abroad is pretreatment + biochemical treatment + membrane system. Pretreatment includes primary pretreatment and secondary pretreatment. Biochemical treatment is mainly MBR process, and membrane system is generally two-stage DTRO, or DTRO+RO. For leachates with lower salinity and poor biodegradability, the MBR process can be omitted. The purification effect of the process system is good, the effluent is stable, and the effluent can meet the standard of Table 2 of the Pollution Control Standard for Domestic Waste Landfills (GB16889-2008). However, this process system has the disadvantage of low water yield. The designed water yield is generally 60% or higher, but with...
