Results of leachate adsorption by slurry consolidation.

Main components of leachate	Concentration before the test (mg/L)	Concentration after the test (mg/L)	Emission standards (mg/L)	Adsorption rate (%)
Pb	25.02	3.25 × 10^−2	1.0	99.87
Cr	5.83	5.83 × 10^−4	1.5	99.99
Hg	2.68	1.87 × 10^−4	0.05	99.93
NH4-N	703.73	1.12	15	99.84
C16H22O4	8.67	0.163	0.2	98.12

Emission standard is the latest pollutant emission standard of China.
