Description

Technical Field

[0001] The utility model belongs to the technical field of organic waste composite dehydration, in particular to an organic waste composite dehydration system. Background Art

[0002] According to data released by relevant departments, my country generates nearly 6 billion tons of various organic wastes in production and life every year, and most of them have a moisture content of more than 70% to 80%. The solid matter in organic wastes that has resource utilization value is basically the solid matter. Therefore, it is necessary to utilize these organic wastes with high moisture content as resources and make them "turn waste into treasure and turn waste into use". The key is to reduce the moisture content of organic wastes efficiently and at low cost.

[0003] In production practice, commonly used organic waste dewatering technologies and equipment include belt filter presses, plate and frame filter presses, screw presses, centrifuges, and vacuum filters, which operate based on mechanical and physical principles, and tank and tower fermenters, which operate based on biological fermentation dehydration. The former generally limit their dehydration efficiency to reducing the moisture content of organic waste from approximately 80% to approximately 60%, which falls short of resource utilization requirements, but further reduction is difficult and significantly increases costs. While the latter can reduce the moisture content of organic waste from approximately 60% to below 40%, they require the addition of a significant proportion of auxiliary materials. In particular, organic wastes such as municipal sludge, which have relatively low nutrient content, require the addition of large amounts of high-energy organic auxiliary materials to adjust the carbon-nitrogen ratio for proper fermentation, significantly increasing treatment costs. Furthermore, there is currently no integrated deep dehydration equipment on the market that combines mechanical and physical dehydration with biological fermentation dehydration. Consequently, most organic waste, particularly municipal sludge, which has a high moisture content and relatively low organic matter and other nutrient content, cannot be effectively treated and utilized in an environmentally friendly manner.

[0004] Based on the actual production needs for environmental protection treatment and resource utilization of organic waste, an innovative integrated equipment integrating mechanical physical dehydration and biological fermentation dehydration has been developed. Without relying on other organic auxiliary materials or greatly reducing dependence on other organic auxiliary materials, it can directly and deeply dehydrate organic waste with a moisture content of about 80% or even higher to a moisture content of less than 40% at high efficiency and low cost, meeting the index requirements of resource utilization. It will be of great benefit to promoting the level of environmental protection management and resource utilization of organic waste in society and promoting the smoother realization of my country's "dual carbon" goals.
