[0142] Implementation method of applying the above-mentioned livestock and poultry manure cleaning, reuse, treatment and resource utilization facilities
[0143] 1 The process flow chart of a facility for cleaning, recycling, and resource utilization of livestock and poultry manure and its implementation method is shown in Figure 8 .
[0144] 2 Implementation method
[0145] The characteristic of the clean reuse mode is that the manure (sewage) after dry cleaning and pen flushing (sewage) is reused and resourced after treatment.
[0146] For the convenience of description, the pen flushing sewage treatment after drying and cleaning the excrement will be described in the front, and the treatment of drying and cleaning the excrement will be described later.
[0147] (1) Pen flushing sewage treatment after drying and cleaning the manure
[0148] The pig manure produced by the live pigs in the pig house every day is cleaned out of the pig house mechanically or manually. After...

Abstract
The invention discloses a livestock manure cleaning and recycling treatment and resource utilization facility and an implementation method thereof. The livestock manure cleaning and recycling treatment and resource utilization facility comprises (1) hutch washing sewage treatment after manure is dried and collected, and (2) treatment of the dried and collected manure including 1/3 of fresh manureis conveyed to a fly larvae breeding greenhouse 11 through a shaftless screw conveyer 10, 2/3 of the fresh manure is conveyed through a mixing and homogenizing pond 12 and a screw extrusion separator13, and separated liquid manure is conveyed to an up-flow type solid anaerobic reactor 14 and a biogas slurry harmless treatment unit 15. The livestock manure cleaning and recycling treatment and resource utilization facility is innovatively characterized in that livestock breeding waste treatment is implemented according to the ideas of cleaning and recycling treatment and resource utilization, 1/3 of the fresh manure is applied to larva breeding, 2/3 of the fresh manure is processed through solid-liquid separation, manure residues are applied to producing bulk organic fertilizers and carbonrods for burning, biogas slurry is processed through harmless treatment and then involved into a water-fertilizer integrated facility, and the liquid manure is processed through sewage treatment and then applied to the water-fertilizer integrated facility for field irrigation/drop irrigation.
Description
technical field [0001] The invention belongs to the field of livestock and poultry manure treatment and resource utilization, and further refers to a livestock and poultry manure cleaning and reuse treatment and resource utilization facility and implementation method. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the demand for livestock and poultry products has increased year by year, and livestock and poultry breeding has become the most active growth point and main supporting industry in my country's rural economy. Then, with the increasing scale and intensification, livestock and poultry farming has become a non-negligible source of pollution. [0003] In the past, tens of thousands of households scattered farming, pig manure, points and other waste soybeans digested by themselves, but the current intensive and large-scale farming has led to the problem of centralized sewage d...
