What is trough composting? What are its advantages and disadvantages?

Trough composting is a composting method in which compost mixture is placed in a long trough structure for fermentation. The oxygen supply of tank compost depends on the mixer, which moves along the longitudinal axis of the tank and stirs the compost during the movement. The stacking depth in the composting pond is 1.2 ~ 1.5m, and the composting fermentation time is 3 ~ 5 weeks.

The advantages of trough composting are: large amount of manure treatment; The fermentation period is short; Generally, it is carried out in a greenhouse, which can collect and treat odor without polluting the air. Because tank composting needs to purchase mixing equipment, and the mixing equipment has high power, high investment cost and high operation cost; The contact part between the mixing equipment and the pile body is easy to wear when rotating at high speed, and it is easy to corrode when it is in direct contact with the fecal mixture, so it needs maintenance and replacement.

Trough compost is suitable for a large number of manure compost.
