Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the specific embodiments.

[0023] First, the fresh cow dung is separated by dry-wet separator or natural sedimentation method. The specific method depends on the scale of the dairy farm. Large-scale farms can use dry-wet separator for separation, and small farms can use non-powered The method of natural precipitation separation; the cow dung and feces pollutants (sewage) obtained after the above steps are put into the secondary sedimentation tank, and the liquid after the secondary precipitation is injected into the fermenter of the unpowered fermentation system, and an appropriate amount of fermentation bacteria is added , EM composite bacterial agent, HEM composite bacterial agent, VT composite bacterial agent or EM, HEM and VT mixed composite bacterial agent, but it should be determined according to the specific temperature. If the temperature is low, it can be added in an appropriate...

Abstract

The invention discloses a method for producing environment-friendly liquid state compound fertilizer by using cattle excrement waste water, and relates to the fields of environment pollution treatment and waste cyclic utilization in animal husbandry, as well as new resource development and the like. The method solves the pollution of breeding industry on the environment and simultaneously provides a new resource substance, namely the environment-friendly liquid state compound fertilizer. The environment-friendly liquid state compound fertilizer uses the excrement waste water obtained by carrying out dry-wet separation or precipitation on fresh cattle excrement as raw material, and finally carrying out the steps of secondary precipitation, fermentation, concentration, filtration, packaging and the like. The method changes the use manner of a cattle excrement waste water resource in prior art, reduces the pollution on environment and simultaneously increases economic benefits.

Description

technical field [0001] The invention belongs to the fields of animal husbandry environmental pollution control, waste recycling, new resource development and the like. Background technique [0002] With the rapid development of the scale and intensification of the dairy farming industry, the problem of environmental pollution caused by the concentrated discharge of dairy cow manure has become increasingly prominent. It has been proven that the pollution of manure from the breeding industry is the biggest pollution to the earth and the air by humans. At present, the number of dairy cows and beef cattle in my country (Including improved dairy cows and large-scale beef cattle farms) there are more than 10 million heads, and each cow produces 35Kg of manure per day, and the annual output of manure is more than 120 million tons. The dry-wet separation method is to use a large amount of water to dilute the cow dung and then separate the particles in the manure. Although this method ...
