Problems solved by technology

[0003] Traditional vegetation blankets can only play the role of bank revetment, greening and soil consolidation, and have little effect on improving soil quality and water quality. In the end, the vegetation growth in the area will still return to the original level, and the north is dry and cold, which is not conducive to Vegetation growth and reproduction

Embodiment Construction

[0022] Such as figure 1 The composite vegetation blanket of residual sludge matrix from a biologically active urban sewage treatment plant is composed of an upper structural layer 1, a vegetation layer 2, a nutrient layer 3, a protective layer 4 and a lower structural layer 5 from top to bottom.

[0023] Both the upper structural layer 1 and the lower structural layer 5 are grid members woven from hemp fibers produced after recycling waste sacks. The average length of the hemp fiber is 30mm-35mm, and the fineness is 0.4-0.7g / km. The surface meshes of the upper and lower structural layers are square staggered meshes, and the mesh size is 0.5mm×0.5mm.

[0024] The vegetation layer 2 is formed by mixing crushed corn stalks, wheat straw, a small amount of fertilizer and grass seeds. The mass percentages of the components are: corn stalks: 58.5-60.5%, wheat straws: 31.5-33.5%, fertilizers: 4.5- 6.5%, grass species: 1.0-3.0%.

[0025] The nutrient layer 3 is composed of modified ...

Abstract

The invention provides a bioactive urban sewage treatment plant excess sludge matrix composite vegetation carpet and application. The composite vegetation carpet is composed of an upper structure layer, a vegetation layer, a nutrition layer, a protection layer and a lower structure layer; the upper structure layer and the lower structure layer are both woven by hemp fiber of waste jute bags, and grids of the upper structure layer and the lower structure layer are arranged in a square staggered mode; the vegetation layer is obtained by mixing crushed corn stalks, wheat straw, grass seeds and a small amount of fertilizer; the nutrition layer is prepared from modified sludge by spraying a fungicide; the protection layer is located under the nutrition layer and prepared from crushed wheat straw. According to the vegetation carpet, the adopted materials are basically solid waste, the active sludge is selected as the nutrition layer, therefore, nutrients can be provided for vegetation, rainwater and domestic sewage can be purified, the soil fertility and the soil quality can be greatly improved, and the advantages of heat preservation, water retention, soil moisture conservation, structure stabilization and the like are achieved.

Description

technical field [0001] The invention relates to waste recycling and the application field of activated sludge, in particular to a bioactive city sewage treatment plant residual sludge matrix composite vegetation blanket and an ecological restoration method using the composite vegetation blanket. Background technique [0002] Vegetation blanket is a product that converts the remaining biomass resources in the agriculture and forestry industries into ecological restoration products according to the concepts of returning fallen leaves to their roots, returning straw to the field, and improving soil. It can be applied to hillsides, sandy soil, river banks, and roads. Parks, football fields, golf courses, etc. are internationally recognized as one of the most effective, cheapest, and easiest products for soil protection, sand control, and greening and environmental protection. [0003] Traditional vegetation blankets can only play the role of bank revetment, greening and soil con...
