Abstract

The invention discloses a water treatment agent and a preparation method of the water treatment agent. The water treatment agent is prepared from the following raw materials in parts by mass: 18 to 24 parts of modified albizia, 7 to 11 parts of herba conyzae canadensis and 12 to 16 parts of pygmy waterlily leaf; preparation of the modified albizia comprises calcining treatment and modification treatment; a modifying solution is prepared from the following components in parts by mass: 8 to 14 parts of sodium polyacrylate, 12 to 17 parts of volcanic soil, 3 to 4 parts of ground quartz, 5 to 7 parts of aluminum oxide powder, 5 to 8 parts of ferrous nitrate and 45 to 50 parts of de-ionized water; the preparation method of the water treatment agent comprises the following steps: washing the herba conyzae canadensis and the pygmy waterlily leaves; chopping, mixing and filtering to obtain filter dreg and juice for later use; adding water into the filtering dreg and immersing; boiling and extracting for two times and mixing with the juice; adding the modified albizia and uniformly mixing; carrying out microwave drying until a mixture is dried; controlling the temperature in a range of 135 DEG C to 140 DEG C and cooling to obtain the water treatment agent. According to the water treatment agent, the dosage is less and the removing rate of phosphorus in phosphorus-containing water source water or sewage reaches 97 percent or more.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water treatment agent and a preparation method thereof. Background technique [0002] Eutrophication refers to excessive discharge of phosphorus and nitrogen-containing compounds into the water body, destroying the original ecological balance, causing algae to multiply rapidly, and the growth cycle is short. After the death of algae and other plankton, they are decomposed by aerobic microorganisms, which continuously consume dissolved oxygen in the water, or are decomposed by anaerobic microorganisms, and continuously produce hydrogen sulfide and other gases, which continuously deteriorate the water quality from two aspects, causing fish and other aquatic organisms mass death. During the decay process of algae and other plankton residues, nutrients such as nitrogen and phosphorus are released into the water for a new generation of algae and other organisms to use. Exc...
