Abstract

This invention relates to the field of sludge treatment technology, and more specifically, to a biodegradable green sludge dewatering drainage board, comprising: a biodegradable drainage board structure, the biodegradable drainage board structure including: a glue-free straw core board and a biodegradable filter membrane wrapped around the glue-free straw core board; one or more longitudinal grooves are formed on the glue-free straw core board to allow water flow, so that water filtered through the biodegradable filter membrane flows in the drainage channel formed between the longitudinal grooves and the biodegradable filter membrane. Both the glue-free straw core board and the biodegradable filter membrane are biodegradable. The glue-free straw core board itself is a natural material, contains no glue, and can be gradually decomposed by microorganisms in the natural environment, preventing incomplete degradation. In stark contrast to traditional plastic drainage boards, this invention avoids the long-term environmental pollution problems caused by non-biodegradable plastics, conforms to the current concept of environmental protection and sustainable development, and helps reduce soil and water pollution, protecting the ecological environment.
