A Comprehensive Guide to Species-Specific Conversion Technologies

1. Poultry Manure Conversion Process
High-Temperature Aerobic Fermentation

Processing Workflow:
① Raw Material Preparation
Collect fresh manure (moisture 50-60%) with bedding materials

② Primary Fermentation

• Use groove-type turners for daily agitation
• Maintain 55-65℃ for 10 days
• Achieve 30-40% volume reduction

③ Secondary Maturation

• Static pile curing for 15-20 days
• Microbial community stabilization

④ Granulation

• Mix with binder (2-3% lignosulfonate)
• Form 3-4mm pellets via rotary drum granulator

Key Parameters:

• C/N ratio adjustment: 25:1 to 30:1
• Germination index: >80%
• Organic matter: ≥45%

2. Ruminant Manure Treatment System
Mechanical Dehydration & Composting

Processing Stages:
▷ Phase 1: Solid-Liquid Separation

• Screw press separator reduces moisture from 75% to 28-32%
• Recover 60-70% liquid for biogas production

▷ Phase 2: Windrow Composting

• Form 1.5m high x 2m wide windrows
• Weekly turning with wheel-type equipment
• Add 5% zeolite for odor control

▷ Phase 3: Bio-enrichment

• Inoculate with phosphate-solubilizing bacteria
• 15-day curing enhances P availability

Output Specifications:

• NPK content: 4-3-3 standard
• Moisture: <15%
• PH value: 6.5-8.0

3. Swine Manure Upcycling Method
Co-composting with Carbon Amendments

Step-by-Step Processing:
✓ Pre-treatment

• Crush straw amendments to 2-3cm fragments
• Mix swine manure with amendments (3:1 ratio)

✓ Thermophilic Phase

• Crawler turner operation every 3 days
• Temperature monitoring (60-70℃ maintained)

✓ Curing & Screening

• 20-day maturation period
• Rotary screener removes >4mm particles

✓ Value-Added Processing

• Optional humic acid extraction
• Pellet coating with beneficial microbes

Quality Benchmarks:

• Humic acid: ≥25%
• Cellulose decomposition: ≥75%
• Heavy metals: Below EU 2019/1009 limits
