Technical Field

The invention relates to the technical field of aquaculture solid waste treatment processes and devices, in particular to a conditioning stirring kettle and a conditioning method for mariculture solid waste.

Background

At present, the total salt content of mariculture solid waste is far higher than that of livestock and poultry culture solid waste, and if the salt content is high, the activity of microorganisms can be limited if aerobic fermentation/aerobic composting is carried out directly, so that the fermentation process cannot be started, and therefore, the process of desalting firstly and fermenting secondly is adopted.

At present, the dehydration and desalination by a physical method are more effective than the desalination by using a desalination agent, because the desalination agent can greatly reduce the pH value, the subsequent experiments find that the microbial activity is also inhibited, partial salt can be removed by dehydration, and then normal fermentation can be carried out by adding wheat straws and microbial agents. In order to realize the dehydration and salt adjustment of seawater solid waste, a screw auger squeezing method, a mesh screen draining method and an inclined scraper lifting method are common methods. The inclined scraper is utilized to lift the sludge and dewater at the same time, and the method causes higher water content after dewatering, so that certain specific working condition requirements cannot be met; partial dehydration can be carried out by using a mesh screen draining mode under the assistance of vibration, the water content is still not low, and the situation that the water is still on the upper surface due to the fact that mud is heavier at the lower side and blocks meshes is often found; the water content can be well controlled by using the auger for dehydration, but the power required for matching is larger.
