The invention discloses a livestock waste nutrient recovery and water quality standard-reaching technical method. According to the invention, primary solid-liquid separation is carried out on livestock waste, the separated solid manure slag is taken as an organic fertilizer raw material nutrient for outward transport for sale for benefit-increasing cycle utilization or returning utilization, scientific circulation uses combination of farming and animal husbandry, urine through emission reduction, solid-liquid separating and interception, sewage and domestic water flow into an equalizing tank,a solid-liquid separating biological slag removal apparatus, a black film methane tank, a combination reaction environmental-protection pool, a MBR membrane pool, and a ball algae treatment pool in order for multilevel processing, during a whole process, solid-liquid-gas omnibearing processing utilization is carried out on waste, the method is characterized in that biogas is used for generating orproduction and living, the processed water is subjected to nutrient recovery and returning utilization, the filtered manure slag stockyard is subjected to organic fertilizer recovery or returning utilization, and the energy cycle utilization is realized. The processed reclaimed water through a chemical reaction can reach standard time-limited zero pollution discharge, and the environmental protection performance is good.
