TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: In the method for processing excess sludge for solar thermal radiation oxygen-enriched fermentation, the dried admixture is crushed clay and the mixture of agricultural waste and garden waste, and the mass ratio of the clay to agricultural waste to garden waste is 5-8:1:5-10. The fermentation material pile (7) exchanges air in the flowing air via a forced channel type air supplying system and a pipe type air leading system; the replaced waste gas is conveyed to a deodorizing system. The laying thinness of the mixed material in step (b) is 60-100 cm. The partial fermentations after step (b) are processed in step (a) to step (c) again. Preferred Processing System: The aerator pipeline systems (8) are arranged at the bottom of the fermentation material pile (7) and the floor of the solar plate thermal radiation region (6); an aerator pipe (9) capable of aerating air and filling air to the fermentation material pile from bottom and blowing out the bad smell in the fermentation material pile; aerator holes (10) are distributed on the aerator pipe (9), and cobbles (11) are filled around the aerator pipe (9); a layer of filtering and adsorbing layer (12) is laid on each of the bottom cobbles and top cobbles of the aerator pipe ditch (8); a high-pressure deodorization sprayer (16) for blowing the bas smell to both ends of the fermentation material pipe and spraying deodorization liquor to remove partial bad smell of the fermentation material pipe is arranged at the position with 0.8-1 m high from the fermentation material pile (7); a jet of the high-pressure deodorization sprayer (16) orients the fermentation material pile (7); a bad smell air absorbing pipe (13) is arranged at 1-1.5 m high from the fermentation material; air absorbing holes (14) are distributed on the air absorbing pipe, and the air outlet end of the air absorbing pipe (13) is connected with an air inlet of a spray deodorization tower for treating bad smell. One or two to three parallel aerator pipe ditches (8) are arranged along the length direction of the fermentation material pile. The aerator holes (10) are distributed at the place inclining to the lower side with 45 degrees at both side walls of the aerator pipe (9); the separated distance of the aerator holes (10) is 5-10 cm.
