From, rush column water directly mixed with excrement, urine carry out subsequent processing, processing method is usually to be carried out with after methane-generating pit anaerobic fermentation
It is separated by solid-liquid separation, isolated solid portion removes production solid organic fertilizer, and liquid portion is handled simultaneously " row up to standard according to sewage
Put ", the drawbacks of this method be a large amount of nutrients dissolutions in a liquid, the SOLID ORGANIC fertilizer nutrient of production is low, of poor quality；And in liquid
Due to being rich in organic matter and N P and K, COD and ammonia nitrogen concentration are high, and common technology of waste water control is difficult to reach discharge mark
Standard, though according to 400 mg/L of limit value COD in existing livestock and poultry breeding industry pollutant emission standard (GB18596-2001),
8 mg/L of 80 mg/L of ammonia nitrogen and total phosphorus, be respectively urban wastewater treatment firm pollutant emission standard (GB18918-2002, one
Grade A standard) in 8 times, 16 times and 16 times of limit value, so-called " qualified discharge " is really the root for causing water eutrophication
