Abstract

The invention relates to a plant extract composite biological flocculant and a preparation method thereof. The biological flocculant comprises the following ingredients in parts by weight: 3-5 parts of pomegranate bark extract, 6-8 parts of persimmon extract, 3-5 parts of pumpkin extract, 1-2 parts of radix astragali extract, 20-30 parts of chitosan and 54-62 parts of polyaluminum ferric chloride.Through a large number of studies, in the biological flocculant, plants with a function of flocculation, adsorbing metal ions and antibacterial plants are selected, and flocculation ingredients, adsorbing ingredients and antibacterial ingredients are extracted by a specific extracting process, so that the best effect of the biological flocculant can be achieved; the polyaluminum ferric chloride is compounded with the flocculation ingredients, the adsorbing ingredients and the antibacterial ingredients, so that the function of the flocculant can be effectively improved, the quality guarantee period of the flocculant is prolonged, and the dosage of the flocculant is reduced.

Description

technical field [0001] The invention relates to a plant extract composite biological flocculant and a preparation method thereof, belonging to the field of water treatment agents. Background technique [0002] Water treatment agent is an important class of fine chemical products, which play an important role in the purification and treatment of industrial sewage and domestic wastewater. It is said that the large-scale use of water treatment agents not only provides humans with a large amount of clean drinking water, industrial and agricultural water, greatly alleviates the harm of polluted water to the environment, but also effectively maintains the balance of the ecosystem. Specifically, water treatment agents are mainly used to remove suspended solids in water bodies, deodorize and decolorize, inhibit bacteria, sterilize, soften water quality, reduce scale formation, and reduce damage to equipment caused by raw water, etc. Therefore, according to their functional characte...
