Problems solved by technology

If the high-concentration pig-raising sewage is directly discharged without effective treatment, it will cause serious pollution to the water, air, and soil in the surrounding area, and even cause significant harm to the health of the surrounding residents.
[0003] At present, domestic large-scale pig farms often use anaerobic-aerobic combined process to treat pig sewage, but this mode has many disadvantages such as long reaction time, large structure volume, and difficulty in meeting ammonia nitrogen standards, and high investment and operating costs in practical applications. , bringing a greater economic burden to farmers
In addition, the essence of the anaerobic-aerobic combined process to treat pig sewage is to convert the organic matter in the sewage into carbon dioxide and nitrogen and discharge it into the atmosphere. This process not only consumes a lot of energy, but also does not effectively recover the carbon source in the sewage. use

Abstract

The invention discloses pig farm sewage treatment packing and multi-element coupling process and a system. The process comprises the following steps: collecting pig farm sewage generated in the breeding process of a pig farm, and separating solid wastes and wastewater in the sewage of the pig farm; planting water hyacinth and laying honeycomb briquette shaped packing in a step-shaped ecological packing pond, and constructing ecological corridor steps for treating separated wastewater by using self-made adsorption honeycomb briquette packing in the ecological packing pond; and mixing the separated solid wastes with the water hyacinth planted in the ecological packing pond, and performing composting, thereby obtaining an organic fertilizer. The process has the beneficial effects that organic matters in pig farm sewage can be efficiently recycled, the additional value of the process is increased in an organic fertilizer compensation mode, the sewage treatment environment of the pig farm is beautified, and the discharged wastewater can stably meet discharge requirements of the Discharge Standard Of Pollutants For Livestock And Poultry Breeding.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding pollution control, in particular to a pig farm sewage treatment filler, a multi-component coupling process and a system. Background technique [0002] With the development of the market economy and the improvement of people's living standards, my country's pig breeding industry is rapidly advancing towards intensification and scale. Large-scale farming can effectively improve the breeding technology and epidemic prevention capabilities of livestock and poultry farms, but it also causes excessive concentration of manure in pig farms, which greatly exceeds the carrying capacity of the natural environment. Relevant studies have shown that a pig farm with 10,000 heads produces 100-150m of sewage every day 3 around, while pig sewage is a typical high-concentration organic sewage, COD, TP, NH 3 -N can be as high as 20000, 300 and 1500mg / L. If the high-concentration pig-raising ...
