Abstract

The invention discloses a solid-liquid separating device used for ecological pig breeding and an ecological breeding system based on the same. The solid-liquid separating device comprises a solid-liquid separating device body, wherein the bottom part of the solid-liquid separating device body is provided with an inclined dung receiving floor; the interior of the solid-liquid separating device body is provided with a baffle plate which separates the area enclosed by the dung receiving floor and four side surfaces of the solid-liquid separating device body into a urine discharge ditch and a dung receiving area; a urine discharge gap is remained between the edge of the bottom part of the baffle plate and the dung receiving floor; the edge of the inner side of the urine discharge ditch is provided with a urine outlet; one end of the dung receiving area is provided with a dung scraping plate capable of moving along the dung receiving floor and the baffle plate; and the rear end of the solid-liquid separating device body is provided with a dung outlet. The solid-liquid separating device provided by the invention realizes successful solid-liquid separation of a hog house; meanwhile, through the overall design of the ecological system, the purpose of zero discharge and recycling utilization of breeding wastes (wastes from pig breeding are utilized for pig breeding) is achieved.

Description

technical field [0001] The invention belongs to the technical field of pig farm breeding waste treatment, and in particular relates to a solid-liquid separation device and an ecological breeding system for pig ecological breeding. Background technique [0002] my country is the world's largest pig raising country and a big pork consumer. In 2014, my country had more than 50 million reproductive sows and more than 700 million live pigs. The per capita pork possession reached more than 40 kilograms, and the annual output value of live pigs and related industries reached 2 The trillion yuan of RMB has become an important pillar industry to ensure the quality of life of the people and increase the income of farmers. With the rapid development of the livestock and poultry breeding industry, while bringing positive benefits to economic development, it also brings inevitable negative impacts on the environment. The large amount of manure produced in the breeding process has caused a...
