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.
