Preferably, also comprise the fertilizer collection device with opening for feed, described aerobic compost reactor has the discharge port that is communicated with fertilizer collection device opening for feed.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) incomplete anaerobic treatment (only acidication stage) is processed and combined with aerobic compost, not only overcome the problem that simple anaerobic treatment and simple aerobic treatment exist, also overcome the problem that aerobic treatment exists after first anaerobic treatment, can reduce simple aerobic treatment energy consumption on the one hand, can save on the other hand the long methanation stage consuming time, thereby significantly shorten the treatment cycle of aerobic treatment after simple anaerobic treatment and first anaerobism, reduce the probability that produces stench in anaerobic process.
(2) due in incomplete anaerobic treatment when (only acidication stage), pH value is lower, without ventilation condition and temperature, rise and do not have simple aerobic treatment fast, all is unfavorable for volatilization and the loss of ammonia nitrogen, thereby reduces nitrogen loss, the raising fertilizer efficiency.
(3) not exclusively anaerobic treatment (only acidication stage) can reduce demand and the power consumption of aerobic compost processing to oxygen, thus save energy.
(4) temperature by monitoring organic solid castoff different heights is at specified range, makes the organic solid castoff of same processing batch can carry out more equably anaerobic digestion; By monitoring the pH value of organic solid castoff, thereby can accurately judge the terminal in anaerobic treatment acidication stage.Like this, can successfully anaerobic hydrolysis-acidification be processed with aerobic compost and process and merge.
