With stricter environmental regulations and farming standards, manure treatment has become a key part of ranch construction and daily operation. Proper manure management ensures compliance and enables resource recycling.

Dairy ranch waste mainly consists of cow dung, urine, flushing water and sewage from daily feeding. Improper disposal leads to water pollution, odor and excessive soil nutrient load. Ranches should select suitable treatment technologies based on scale, manure collection mode, land absorption capacity and local environmental rules.

Common solutions include solid-liquid separation, anaerobic digestion, composting, stabilization ponds and land application. Solid-liquid separation reduces downstream treatment pressure; anaerobic digestion produces biogas for energy recovery; composting converts solid manure into organic fertilizer.

From an ecological cycling perspective, manure treatment should be integrated with on-farm planting. Treated biogas slurry and compost can be applied to farmland and forage bases, forming a closed loop: forage planting – dairy farming – manure return to field – ecological circulation.
