Abstract

The invention discloses plant dip dyeing liquid used for purifying a nitrogen and phosphorus polluted water body and a preparation method thereof. According to a formula, the plant dip dyeing liquid is composed of the following raw materials of, by weight, 10-50 parts of calamus, 10-50 parts of water spinach, 1-10 parts of a potassium permanganate solution, 100-200 parts of allyl monomers, 60-150 parts of clay, 10-30 parts of auxiliary raw materials and 500-1000 parts of sterile water. The calamus and the water spinach are used as the plant raw materials, extracted and combined with the two materials of the allyl monomers and the clay, the nitrogen and phosphorus treatment degree is improved, the plant dip dyeing liquid is low in cost, and only swells instead of being dissolved, the mass transfer resistance to an adsorbent in the adsorption process can be reduced to enable an adsorption system to rapidly reach adsorption equilibrium, and the using range of the plant dip dyeing liquid prepared from the calamus and the water spinach through dilution is enlarged.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a plant liquid for purifying water body nitrogen and phosphorus pollution and a preparation method thereof. Background technique [0002] With my country's industrial progress and social development, water pollution has become increasingly serious and has become a difficult problem in environmental governance. According to monitoring by the environmental department, at least 100 million tons of untreated sewage is discharged directly into water bodies every day in cities and towns across the country. The water quality of more than half of the country's seven major water systems is polluted, 1 / 3 of the country's water bodies are not suitable for fish, 1 / 4 of the water bodies are not suitable for irrigation, 90% of urban waters are seriously polluted, and 50% of urban water sources are not suitable for drinking water standard. These statistics continue to grow as ...
