Embodiment 1

[0028] A garden greening nutrient soil prepared by using urban waste, including 46 parts of urban domestic sewage sludge, 12 parts of kitchen waste and biogas residue, 18 parts of greening waste, 3 parts of perlite, 8 parts of vinegar lees, and potassium permanganate 8 parts and 5 parts lime.

[0029] A method for preparing garden greening nutrient soil prepared from urban waste is as follows:

[0030] The greening waste is crushed and the particle size is 20 mesh after crushing;

[0031] Mix 46 parts of urban domestic sewage sludge, 12 parts of kitchen waste biogas residue, and 18 parts of greening waste according to the above weight parts to obtain main mixture A;

[0032] Add 1 part of perlite, 4 parts of vinegar grains, 3 parts of potassium permanganate, and 3 parts of lime to Mix A by weight, control the C / N ratio of the mixture to 20, and stir evenly to obtain Mix B;

[0033] The mixture B is stacked in a stack for aerobic fermentation to obtain a fermentation mixture; the stack ...

Abstract

The invention discloses a landscape greening nutritious soil preparing by using urban wastes and a preparation method thereof. The nutritious soil comprises, by weight, 40-60 parts of urban domestic sewage sludge, 10-20 parts of kitchen waste biogas sludge, 15-20 parts of greening wastes, 2-4 parts of organic culturing mediums, 7-12 parts of vinegar dregs or straw, 4-8 parts of potassium hypermanganate and 2-6 parts of lime. The method for preparing the landscape greening nutritious soil using the urban wastes is a secondary fermentation preparation method. The nutritious soil prepared by thesecondary fermentation method fully utilizes three kinds of wastes and pollutants in a city, organic culturing mediums of perlite, vermiculite and the like are added to allow the prepared landscape greening nutritious soil has good deodorizing effect, the pH is turned to slight acid from neutral, the nutritious soil has the characteristics of water preserving and air permeability, the content of organic matters, nitrogen, phosphorus and potassium is greatly improved, the use of chemical fertilizers is reduced, and ecological cycle development is achieved.

Description

Technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a garden greening nutrient soil prepared by using urban waste and a preparation method thereof. Background technique [0002] In recent years, with the development of cities and the increase in population, the discharge of urban sewage sludge has been increasing. It has become necessary and urgent to use sewage sludge waste generated by urban sewage plants, and urban sludge is rich in The organic matter and nutrients contained in it become the necessary conditions for its use. [0003] With the rapid development of urban greening construction in my country, urban garden greening wastes such as lawn trimmings and street tree buildings are also increasing day by day. Disposal by incineration and landfill will cause environmental pollution and waste of resources. The main chemical components of garden waste are polysaccharides, protein, cellulose, lignin, etc., which is a ...
