Abstract

The invention discloses a rubbish percolation liquid disposing technique and system based on film biological reactor-nanometer filter film technique, which comprises the following steps: A. proceeding primary physicochemical disposal for rubbish percolation liquid; removing large particle and heavy metal material in the rubbish percolation liquid; forming front disposal water; B. adopting film biological reactor to do filter film disposal; generating hyperfiltration membrane water; C. filtering hyperfiltration membrane water through nanometer filter system; generating and outputting clean water. The system contains at least reacting pond, sediment pond and relative pump equipment to dispose primary physicochemical disposal, which also concludes nanometer filter system to do filtering disposal for water in the hyperfiltration membrane to output clean water.

Description

technical field [0001] The invention relates to biochemistry, in particular to a landfill leachate treatment process and system based on membrane bioreactor-nanofiltration membrane technology. Background technique [0002] Landfill leachate is the product of the gravity flow of liquid in the landfill, mainly from precipitation and the water contained in the garbage itself. There are many factors that may affect the properties of the leachate during the flow of the liquid, including physical factors, chemical factors and Biological factors, etc., so the wastewater quality of landfill leachate varies within a considerable range. Generally speaking, its pH value is 4-9, chemical oxygen demand (COD: Chemical Oxygen Demand) 2000-62000mg / L, biochemical oxygen demand (BOD: Biochemical Oxygen Demand) 60-45000mg / L, ammonia nitrogen (NH3- N) 1000 ~ 3000mg / l, in addition to containing a variety of high concentrations of heavy metal ions and a variety of pathogenic microorganisms, if t...
