Process and facility for the treatment of livestock waste

Abstract

The invention discloses a process and facility for the treatment of livestock waste. The invention provides an efficient system for treating livestock waste, particularly waste from cattle or pig farming. The new facility and method employ special transfers of slurry streams through ASBR, SBR, and a unique pretreatment reactor, resulting in treated water, quality compost, and biogas.

Description

Processes and equipment for treating livestock waste technical field The present invention relates to the treatment of livestock waste. More specifically, the present invention relates to systems and processes for converting livestock waste into compost, treating water, and energy. Background technique Waste disposal is a key issue in most developed countries since waste, especially livestock waste, can cause serious environmental and economic problems. Large farms - 10,000 animals and more - can stress ecosystems and create intractable short- and long-term problems. In order to prevent ecological catastrophe, various countries have enacted laws to limit the amount of livestock waste that can be spread per unit of surface per year. For example, in Europe, dispersal restrictions based on waste nitrogen content have recently been introduced, effectively limiting the size of pig farms. Traditionally, microbial action has been utilized to treat organic matter containing ex...
