Apparatus for preparing ecological fertilizer using animal-bird feces

Abstract

The invention relates to a device to make biology fertilizer from livestock dejection. It includes material intake, material outlet, gate valve, marsh gas control valve and jar. The main technology is that: the identity cavity is separated into anaerobic cavity and aerobic cavity, the outlet pipe end of returning pump extending into anaerobic cavity and connecting to gas nozzle, the output end of sludge pump extending into identity anaerobic cavity and connecting to spray pipe, top part of identity aerobic cavity is set light-passing board, and the output end of burst device connects to burst pipe of aerobic pipe. The invention has the advantages of high intention, super thin, electric energy saving, low running cost, and could effectively improve producing efficiency and quality of biology fertilizer.

Description

technical field

[0001] The invention relates to a harmless treatment device for livestock and poultry manure, in particular to a device for preparing ecological fertilizer from livestock and poultry manure by anaerobic biological method, the by-product of which is biogas, which is also suitable for chemical industry and urban sewage governance. Background technique

[0002] At present, with the rapid development of animal husbandry, the stacking of livestock and poultry manure in farms and the discharge of livestock and poultry manure sewage have brought serious environmental pollution. Therefore, prevention and control of pollution, elimination or reduction of pollution sources have become the primary issues that must be solved in current farms. Livestock and poultry manure from farms, the sewage content is large, it is in the form of colloidal fluid, it is difficult to dehydrate, and the smell is foul, but it is rich in nitrogen, phosphorus, potassium, trace elements and ...
