Fujian Pig Farm Composting Tank Project

Pig Manure Composting System, Fujian

Project Overview

Location: Fujian Province, China

Industry: Large Pig Farming Operation

Project Scale: 4 Phases

Installed Equipment: 12 sets of 150 m³ JinDi Closed Aerobic Composting Tanks

Application: Pig manure → Biogas → Solid–liquid separation → Aerobic composting → Organic fertilizer

Process Flow

Pig Manure Collection & Anaerobic Digestion
Raw pig manure first enters the biogas digester for anaerobic fermentation, producing renewable biogas energy for farm use.

Solid–Liquid Separation
The digested slurry (biogas liquid) and biogas residue are sent to a solid–liquid separator for efficient separation.

 Aerobic Fermentation in JinDi Composting Tanks
The separated biogas residue is fed into JinDi fully enclosed aerobic composting tanks.
Under high temperature, continuous aeration, and intelligent automatic control, the material undergoes deep aerobic fermentation.

7–10 Days Rapid Fermentation
After 7–10 days, pig manure is fully decomposed and converted into stable organic fertilizer base material.

Curing & Land Application
The composted base fertilizer is further cured and then returned to farmland, achieving:

Harmless treatment

Reduction of waste volume

Resource recovery

This project enables the farm to transition to a green, circular livestock farming model.
