Problems solved by technology

[0003] Traditional biogas digesters are generally monolithic structures built with reinforced concrete structures, which are costly and difficult to construct, and there are the following problems in the process of use: (1) Digestive residues are difficult to clean and block the biogas digesters, affecting the normal use of the biogas digesters; (2) ) liquid surface "crusting", which affects the normal gas production of the biogas digester and also creates potential safety hazards
[0004] CN101045901 discloses a conjoined biogas digester, the purpose of which is to treat sewage, and to leave as much sludge as possible in the biogas digester, which will cause blockage of the fermentation tank due to long-term accumulation, and the purpose of the conjoined biogas digester is to expand the volume; CN104328035 discloses a The biogas digester system mainly produces biogas fertilizer, and the soft biogas digesters are connected by sludge pumps, which requires high energy consumption and large investment in equipment

Embodiment 1

[0059] A method for ecological treatment of pig farm manure liquid, comprising the steps of:

[0060] 1. Separation of the source of the barn and water saving: the rain and drinking water are separated, and the rain and drinking water are discharged to the ditch outside the barn instead of being mixed into the feces and urine. Water-saving flushing of the barn, mechanical scraping of manure or manual dry cleaning Manure, at the source of the barn, rainwater and drinking water will not be mixed into the manure and urine, so as to minimize the amount of manure and urine. Clean the barn with a high-pressure water gun or even high-pressure air, mechanically scrape the manure or manually dry the manure to clean it out The pig manure is subjected to high-temperature aerobic fermentation to produce solid organic fertilizer 403, and the pig manure and flushing water are transported to the regulating tank 201;

[0061] 2. Mesophilic anaerobic fermentation of manure liquid:

Embodiment 2

[0075] A method for ecological treatment of pig farm manure liquid, comprising:

[0076] 1. Separation of the source of the barn and water saving: the rain and drinking water are separated, and the rainwater and drinking water are discharged to the ditch outside the barn instead of being mixed into the excrement. At the source of the barn, rainwater and drinking water are not mixed into the feces and urine to minimize the amount of feces and urine. Cleaning the barn uses high-pressure water guns or even high-pressure air. 201;

[0077] 2. Mesophilic anaerobic fermentation of manure liquid:

[0078] (1) open solenoid valve 506d, tap water replenishes water to low-temperature heat preservation water tank 504 automatically, open solenoid valve 506f, low temperature heat preservation water tank 504 utilizes height difference under the control of detection control system 106, automatically replenishes water to high temperature heat preservation water tank 503, opens solenoid valve...

Abstract

A manure and sewage liquid ecological treatment system for a livestock and poultry farm, comprising a source separation-supporting water-saving enclosure (101), a pollution control factory (102), a feed factory (103), and a supporting planting land (107). The pollution control factory (102) comprises the source separation-supporting water-saving enclosure (101), a high-temperature aerobic solid fermentation system, a medium-temperature anaerobic liquid fermentation system (104), a heating and heat balancing system (105), and a measurement and control system (106). A regulation pool (201) is connected to a feed port of the medium-temperature anaerobic liquid fermentation system (104) via a feed pump, biogas generated by the medium-temperature anaerobic liquid fermentation system (104) is transferred to the heating and heat balancing system (105), and the heating and heat balancing system (105) is connected to a heating coil (304) of the medium-temperature anaerobic liquid fermentation system (104) through a pipeline. The system uses a liquid organic-inorganic compound fertilizer (404) and a liquid microbial fertilizer (405) produced by the pollution control factory (102) for watering and drip irrigation of crops grown on the supporting planting land, and forage grass is used as a feed raw material for the feed factory, reducing cost for breeding, improving a nutritional level of feed, and promoting the harmonious development of farming and the environment.

Description

technical field [0001] The invention belongs to the field of environmental protection technology, and in particular relates to a system and method for ecological treatment of excrement liquid in livestock and poultry farms. Background technique [0002] In recent years, the aquaculture industry has developed rapidly towards intensification and scale. While providing the market with rich and high-quality livestock and poultry products, it also brings a large amount of pollutants such as feces and urine. cause serious pollution. [0003] Traditional biogas digesters are generally monolithic structures built with reinforced concrete structures, which are costly and difficult to construct, and there are the following problems in the process of use: (1) Digestive residues are difficult to clean and block the biogas digesters, affecting the normal use of the biogas digesters; (2) ) liquid surface "crusting", which affects the normal gas production of the biogas digester, and also...
