Embodiment 1

[0027] Embodiment 1 produces water purification carbon material with activated sludge and landscaping waste

[0028] 1. Activated sludge

[0029] More than 50% of the substances in activated sludge are organic matter, which contains about 60%-70% of crude protein, about 25% of carbohydrates, and only about 5% of inorganic ash. The carbon content in the sludge is relatively high, and its composition can be obtained by molecular formula C 5 h 7 NO 2 Said that the theoretical carbon content is about 53%. Studies have shown that activators such as inorganic salts (such as ZnCl 2 , KOH, H 3 PO 4 etc.) for impregnation and activation treatment, and pyrolysis and carbonization at a certain temperature to obtain activated carbon.

[0030] 2. Pretreatment of garden waste

[0031] Garden waste mainly refers to the plant residues produced by the natural fall of garden plants or artificial pruning, mainly including tree branches, fallen leaves, grass clippings, flower rot, and shr...

Embodiment 2

[0066] Embodiment 2 produces water purification carbon material with activated sludge and landscaping waste

[0067] According to the method of embodiment 1, the water purification carbon material is produced, and the difference is that the raw material formula (by weight) of the water purification carbon material is: 1. black charcoal powder: 12 parts; 2. activated sludge: 80 parts; 3. quicklime: 8 parts.

Embodiment 3

[0068] Embodiment 3 produces water purification carbon material with activated sludge and landscaping waste

Abstract

The invention discloses a water purification charcoal material as well as a production method and application thereof, and belongs to the production field of water purification charcoal materials. The water purification charcoal material is prepared from the following raw materials: black charcoal powder, active sludge and quicklime. The invention also discloses a production method of the water purification charcoal material. The production method comprises the following steps: mixing the black charcoal powder and the active sludge uniformly, then adding the quicklime, then performing covered moistening after mixing, and performing vacuum pugging, extruding granulation, drying and pyrolysis to obtain the water purification charcoal material. According to the preparation method disclosed by the invention, garden wastes and the active sludge are used as raw materials for producing the water purification charcoal material, thereby realizing recycling application of the garden wastes and solving the problem of disposal of sludge; the produced water purification charcoal material not only can remove organic substances in water but also can remove inorganic pollutants including heavy metal ions and the like in water, and can be applied to river course water purification, sewage treatment and lake or wetland water body purification to realize treatment of wastes with processes of wastes against one another.

Description

technical field [0001] The invention relates to a water-purifying carbon material, and also relates to a method for producing the water-purifying carbon material by using activated sludge, belonging to the production field of the water-purifying carbon material. Background technique [0002] Activated sludge is a general term for microbial groups and the organic and inorganic substances they are attached to. Microbial groups mainly include bacteria, protozoa and algae. Activated sludge is characterized by high water content, perishability, strong odor, and contains a large number of pathogenic bacteria, parasite eggs, heavy metals such as chromium and mercury, and toxic, harmful and carcinogenic substances that are difficult to degrade such as dioxin. Without effective treatment and disposal, it is very easy to cause secondary pollution to groundwater and soil, directly threaten environmental safety and public health, greatly reduce the environmental benefits of sewage trea...
