What is the impact of food waste dehydrator on waste treatment?

Food waste has the physical and chemical characteristics of fixed source, large quantity, high organic content, high water content, high oil and salt content, rich nutrition, less toxic and harmful substances, etc. Food waste is produced in the daily life of residents. Food waste has a high content of organic matter. Research shows that the organic matter content of food waste accounts for the majority of its dry matter. The water content of food waste is generally more than 70%, which brings great difficulties to its collection, transportation and treatment. Food waste contains high levels of oil and salt. The research shows that the crude fat accounts for a large proportion of food waste, and the content of NaCl is high. The content of nitrogen, phosphorus, potassium and other nutrient elements is high, and the fertilizer utilization value is high. In addition, compared with other wastes, food waste contains less toxic and harmful substances, but it is easy to rot and smell, breed bacteria, and cause disease transmission.

Goal of kitchen dehydrator: The goal of kitchen waste treatment is mainly resource utilization and reduction. Different treatment goals require different treatment technologies. The recycling of food waste hopes to obtain products with no impurities and high fertilizer content; The purpose is to reduce the external discharge of food waste. family Food waste treatment Technology often combines the two goals of reduction and recovery, but sometimes the two goals cannot be combined well, resulting in limited application scope of technology.

The food waste dehydrator can be used for anaerobic digestion of food waste, and the equipment investment cost is not high. At present, China has started large-scale implementation from the initial exploration stage. The local classification and treatment of household kitchen waste can not only reduce the difficulty of collection, transportation and treatment of household waste such as community and municipal waste, but also plant and produce organic fertilizers for family balconies and garden gardens. It is widely used in developed countries in Europe and America.

Why promote Food waste treatment equipment Use of?

Dry discharge is to separate the water in the kitchen waste from the solid matter, and then directly discharge it into the municipal sewer to compress the solid matter into blocks for storage and treatment. The dried feed is similar to the crushed feed, which has the characteristics of small floor area, low cost, convenient operation, etc. There are also some shortcomings, which are mainly reflected in: there is no supporting household waste treatment equipment, and the municipal sewage also has the characteristics of high oil content. Food waste has high organic content, low carbon nitrogen ratio and high comprehensive nutrient content, which is very suitable for composting raw materials.
