Milk cow and live pig culturing farm manure low-cost high-efficiency fermentation processing system

Abstract

The invention provides a milk cow and live pig culturing farm manure low-cost high-efficiency fermentation processing system. The milk cow and live pig culturing farm manure low-cost high-efficiency fermentation processing system comprises a primary anaerobic pond and a secondary anaerobic pond; the primary anaerobic pond comprises a pond body a, gas storage black membrane, impermeable membrane, aheating coil pipe, and a water distributing system; the water distributing system is arranged on the upper part of the bottom of the pond body a, and is composed of pipelines; the pipelines are provided with water spraying nozzles; the pipelines are combined, and are connected with a water inlet pump; stainless steel wires are fixedly arranged on the upper part of the pond body a; biological filling material strips are fixedly arranged on the stainless steel wires; the heating coil pipe is arranged to be close to the pond wall; the secondary anaerobic pond comprises a pond body b, gas storageblack membrane, and impermeable membrane. The milk cow and live pig culturing farm manure low-cost high-efficiency fermentation processing system is beneficial for uniform mixing of sewage, is capable of ensuring the temperature needed by fermentation, is capable of realizing full contact of biological filling material with sewage, is provided with the secondary anaerobic pond, so that sewage fermentation efficiency is increased, and complete sewage fermentation is realized.

Description

technical field [0001] The invention relates to a low-cost and high-efficiency fermentation treatment system for cow and pig farm feces, belonging to the technical field of wastewater treatment. Background technique [0002] In recent years, my country's animal husbandry has continued to develop steadily, and the level of large-scale breeding has been significantly improved, ensuring the supply of meat, eggs and milk. However, a large amount of breeding waste has not been effectively treated and utilized, which has become a major problem in rural environmental governance. [0003] Shandong is a large livestock and poultry breeding province. In 2016, the province's total output of meat, eggs and milk was 14.74 million tons, accounting for nearly 10% of the national total. The total output value of animal husbandry was 254.1 billion yuan, ranking among the top in the country for many years. At the same time, with the rapid development of large-scale breeding, livestock and pou...

AI Technical Summary

Problems solved by technology

The structure of this utility model is relatively simple, but there is no warming measure, and due to seasonal restrictions, the sewage treatment effect is not good in cold seasons; there is no stirring and water distribution device, the sewage treatment effect is not good; and the contact area between the biological filler and the sewage is small, resulting in Fermentation effect is not good
