Abstract

The invention relates to a method for preparing a sludge-straw fibre composite material and application. Municipal sludge, straw fibre and industrial waste slag (desulfurized clinker and steel slag) are used as raw materials to prepare a sludge-fibre micelle copolymer by sludge modification technology and copolymer even stirring technology; the sludge-fibre micelle copolymer is used for ecological protection and restoration of a rock slope, a clay slope and a landfill field slope. The sludge-fibre micelle copolymer prepared by the technology recycles and utilizes sludge and straw fibre which are difficult to process; and compared with various green substrates, the sludge-fibre micelle copolymer does not need to add nitrogen, phosphorus, potassium and organic fertilizer to soil, reutilizes waste and greatly reduces cost. The straw fibre improves the tensile and flexural mechanical performance of the sludge-fibre micelle copolymer and further achieves the mechanical strength index of the slope protection. Grass seeds are mixed to the copolymer; and the hydrological effect of plant and mechanical reinforcement effect of a plant root system are utilized to effectively circulate moisture and achieve the functions of reinforcing the slope and greening environment.

Description

technical field

[0001] The method for ecological slope protection of the sludge-straw fiber composite material of the present invention is generally applicable to the ecological protection and restoration of rock slopes, clay slopes, and landfill slopes, and belongs to the fields of ecological environment, geotechnical engineering, and agriculture. Background technique

[0002] With the accelerated pace of construction of urban sewage treatment facilities and the improvement of the centralized sewage treatment rate, the amount of sludge produced by sewage treatment plants has grown rapidly. According to the national "Eleventh Five-Year Plan", my country will increase its daily sewage treatment capacity by 45 million tons, and the centralized treatment rate of urban sewage will reach 70%. One of the environmental problems to be solved. How to carry out harmless treatment and resource utilization technology of municipal sludge is a problem that governments all over the world a...
