The invention relates to a breeding
sewage treatment technology. The breeding
sewage treatment technology comprises the following steps that 1,
sewage drained from a breeding farm is collected through a hoisting shaft; 2, filtering is conducted; 3, anaerobic
fermentation is conducted; 4, an
ammoxidation reaction is conducted for 1 day to 2 days to decrease the
ammonium nitrogen concentration in the sewage; 5, an
aerobic reaction is conducted for 1 day to 2 days at the temperature of 15 DEG C to 25 DEG C, and COD and
ammonium nitrogen in the sewage are degraded through
aerobic bacteria to decrease the COD concentration and the
ammonium nitrogen concentration; 6, the sewage subjected to the
aerobic reaction is delivered into a
biodegradation planting
greenhouse to degrade COD and
ammonium nitrogen in the sewage and purify water; 7, the
purified water is used for farm
irrigation. According to the technology, the concentration of
suspended solids,
ammonium nitrogen and organic pollutants in the sewage can be effectively decreased to the standard level, the whole treatment process achieves full
biodegradation, no secondary
pollution is generated, the removal effect of the
suspended solids is good in the filtering link, the subsequent
sewage treatment difficulty is reduced, the treatment cost is low, filtered
sludge is naturally dried,
dewatering does not need to be conducted through
sludge dewatering equipment, and the treatment cost is low.
