Embodiment 1

[0030] A new method for the harmless treatment of breeding manure, the treatment process includes the following steps:

[0031] (1) Mixing: Mix pig manure and farm sewage evenly in the proportion of 250 parts of pig manure and 800 parts of farm sewage;

[0032] (2) Blending: blend the high-temperature industrial waste liquid and the mixed material in the adjustment tank at a ratio of 500 parts: 1050 parts to increase the temperature of the material to above 40°C;

[0033] (3) Adjust pH: adjust the pH of the fermentation broth to 6.8-7.2;

[0034] (4) EGST temperature-controlled anaerobic fermentation: Pump the material after pH adjustment into the EGST anaerobic reactor, inoculate biogas engineering strains, the inoculation amount is 3-5% of the material mass ratio, temperature-controlled fermentation, the fermentation process Stir continuously in the reactor, and ensure that the pH in the reactor is between 6.8 and 7.2, and collect biogas;

[0035] (5) Collect biogas residu...

Abstract

The invention discloses a new method for harmless treatment of livestock feces. By the method, biogas anaerobic fermentation is performed on the livestock feces first and then a solid-liquid coexistent two-step fermentation process is performed on the livestock feces to prepare an efficient organic biofertilizer, so that feces in a pig farm is efficiently treated and up-to-standard discharge and high-value comprehensive utilization are achieved. The method has the advantages as follows: 1, recycle of the livestock feces in the pig farm is achieved, a recycling industrial chain of farming, feces, biogas, an organic fertilizer and planting is formed, and a huge demonstrating role and a significant leading role are played in aspects of structural adjustment, quality improvement and efficiency increase of agriculture and animal husbandry industries; 2, high-temperature industrial waste liquid generated during agricultural product processing is innovatively used for heating fermenting raw materials, so that warm fermentation in a biogas project is guaranteed, the first industry, the second industry and the third industry are integrated together, and thus a typical demonstrating role in modern circular economy is played; 3, the method adopts the solid-liquid coexistent two-step fermentation process, so that a separate control way in the conventional treatment process is reduced, the treatment cost is reduced and the efficacy of a product is improved.

Description

technical field [0001] The invention relates to a new method for harmless treatment of breeding manure, belonging to the technical field of environmental protection treatment. Background technique [0002] With the development of social economy and the adjustment and optimization of rural industrial structure, the pig breeding industry has developed rapidly, and the scale of large-scale and intensive pig farming has continued to expand, gradually replacing traditional decentralized farming, which has become an inevitable trend in the development of animal husbandry. In recent years, my country's livestock and poultry industry has developed rapidly, and pig breeding has become an important way to increase agricultural efficiency and farmers' income. However, with the development of animal husbandry, a large amount of breeding manure has polluted the environment. The pollution of the environment and the impact on its own sustainable development have become the main factors res...
