Embodiment 1

[0009] A compound bio-growth-promoting agent for repairing polluted river bottom mud, its components and content (weight percentage) are: tourmaline 8%; active zeolite 91%; biochemical fulvic acid 0.8% and CoCl 2 ·6H 2 O 0.2%. Said tourmaline is made of natural tourmaline raw material, which is processed into tourmaline superfine powder by crushing, with a particle size of 800 mesh. The active zeolite is made of natural zeolite raw material first activated at 300°C, and then crushed into active zeolite powder with a particle size of 200 mesh. The above tourmaline, activated zeolite, biochemical fulvic acid and CoCl 2 ·6H 2 O After drying, crushing and mixing, it is a composite biological growth promoter for repairing polluted river bottom mud.

Embodiment 2

[0011] A compound biological growth-promoting agent for repairing polluted river bottom mud, its components and content (percentage by weight) are: tourmaline 10%; active zeolite 89%; biochemical fulvic acid 0.9% and CoCl 2 ·6H 2 O 0.1%. Said tourmaline is made of natural tourmaline raw material, which is processed into tourmaline superfine powder by crushing, and the particle size is 1000 mesh. The active zeolite is made of natural zeolite raw material first activated at 400°C, and then crushed into active zeolite powder with a particle size of 300 mesh. Tourmaline, active zeolite, biochemical fulvic acid and CoCl 2 ·6H 2 O After drying, crushing and mixing, it is a composite biological growth promoter for repairing polluted river bottom mud.

Embodiment 3

[0013] A compound bio-growth-promoting agent for repairing polluted river bottom mud, its components and contents (percentage by weight) are: 12% tourmaline; 87% active zeolite; 0.8% biochemical fulvic acid and CoCl 2 ·6H 2 O 0.2%. Said tourmaline is made of natural tourmaline raw material, which is processed into tourmaline superfine powder by crushing, with a particle size of 1200 mesh. The active zeolite is made of natural zeolite raw material first activated at a high temperature of 400°C, and then crushed into active zeolite powder with a particle size of 400 mesh. Tourmaline, active zeolite, biochemical fulvic acid and CoCl 2 ·6H 2 O After drying, crushing and mixing, it is a composite biological growth promoter for repairing polluted river bottom mud.

Abstract

The invention relates to a complex biological growth promoter used for recovering river bottom sediment, which comprises the following components (by weight percent: 5 to 14 % of electrical stone, 85 to 94% of active zeolite, 0.3 to 1% of biochemical fulvic acids and 0.1 to 0.3% of CoCl2.6H2O, wherein natural electrical stone is used as the raw material of the electrical stone, and the natural electrical stone is crushed into super fine powder with the granularity of 800 to 1200 meshes; natural active zeolite is used as the raw material of the active zeolite, the natural active zeolite is firstly activated at the high temperature of 300 to 600 DEG C and then crushed into active zeolite powder with the granularity of 100 to 500 meshes; and the complex biological growth promoter used for recovering river bottom sediment can be obtained after the electrical stone, the active zeolite, the biochemical fulvic acids and the CoCl2.6H2O are dried, crushed and mixed. The invention has the characteristics of activity preservation, simple production process and low production cost and suitability for large-size application, and is not easy to lose along with water.

Description

Technical field: [0001] The invention relates to a composite biological growth promoter for repairing polluted river bottom mud, and belongs to the technical field of ecological restoration of non-point source polluted water bodies. Background technique: [0002] In recent years, with the rapid development of the national economy, the situation of water pollution in my country has become increasingly severe. Industrial wastewater, agricultural non-point source pollutants and domestic sewage along the river are discharged into the river, which makes the water quality of the river worse, and the bottom mud of the river bed becomes thicker and thicker. Polluted sediment seriously affects the safety of drinking water for residents, the image of water landscape and the ecological environment of surrounding areas. In order to solve the above problems, methods such as sediment dredging and sewage interception are often used, but these methods cannot truly establish a river ecologi...
