Dry-cleaning type comprehensive feces treatment method for district type dairy farm with more than 500 livestock on hand

Abstract

The invention discloses a dry-cleaning type comprehensive feces treatment method for a district type dairy farm with more than 500 livestock on hand. The dry-cleaning type comprehensive feces treatment method comprises the dry-cleaning type feces treatment technology; sewage is collected by a concealed pipe and enters an anaerobic tank to ferment, the fermented sewage is aerated and denitrified in an aerobic tank, parts of the treated sewage can be used for backwashing milking parlors, the rest can be mixed with clean water according to a certain proportion in an return irrigation tank, and the mixture can be utilized in the planting industry; in non-irrigation seasons, the liquid in the aerobic tank can enter multi-stage biological purification storage pond so as to perform deep treatment, finally, reclaimed water in the return irrigation tank is mixed with clean water according to a certain proportion, and the mixture is adopted in irrigation in the planting industry. In the dry-cleaning type comprehensive feces treatment method, classified collection and classified treatment of feces are simultaneously taken into account, the method has seasonal adaptive capacity, a certain storage and deep purification capability, and the combination of planting and breeding is realized.

Description

technical field [0001] The invention relates to a technology for comprehensive treatment of manure and sewage in dairy farms, in particular to a method for comprehensive treatment of manure and sewage in dry-cleaned dairy farms with more than 500 cows. Background technique [0002] According to the Ministry of Agriculture's "National Advantageous Agricultural Products Regional Planning and Layout 2008-2015" statistics, at present, my country's per capita dairy product consumption is only equivalent to 1 / 4 of the world's average level and 1 / 12 of that of developed countries, and there is broad room for development. In recent years, with the increase in the demand for dairy products and driven by the cow-dominant areas, my country's dairy industry has continued to develop at a high speed, and a number of star enterprises and well-known brands have emerged, achieving remarkable results. According to statistics from the Animal Husbandry Yearbook, the national breeding volume in ...

Problems solved by technology

The vast majority of farms, especially small and medium-sized farms, mainly use the dry manure cleaning process. Compared with the manure production and discharge of water flushing dairy farms, the manure is mainly collected in the form of solids. The amount of aquaculture wastewater is relatively small, and the organic matter content in the wastewater is low. However, if it is not treated and discharged randomly, it will also cause serious environmental pollution. It is necessary to develop an economical, applicable and targeted manure treatment process. is the key problem to be solved in the present invention
