Landfill Leachate Toxicity Removal in Combined Treatment with Municipal Wastewater

Table 4

Characteristic of “new” landfill leachate (nondiluted).

Parameter	Unit	Range	Average±SD^∗	Median
TOC	mg/L	1460–2300	1950±350	2010
COD	mg/L	1873–3600	2560±615	2330
BOD	mg/L	150–273	210±55	210
N NH4	mg/L	971–1250	1100±92	1200

^∗SD: standard deviation; number of measurements 𝑛=16; time-dependent variation of parameters value was caused by unstable composition of leachate.
