The present invention discloses a water treatment agent composition, which contains an amino acid having a scale inhibiting and corrosion inhibiting effect, a macrolide antibiotic having a sterilization effect, and an enzyme cooperating with the amino acid and the antibiotic and providing a synergy effect. The present invention further discloses applications of the water treatment agent in water treatment. According to the present invention, the performance evaluation results of the water treatment agent show that the calcium carbonate scale inhibiting rate is more than 99%, the corrosion rate of the dynamic simulation test is 0.023 mm / a, and the number of the 72 h heterotrophic bacteria can minimally achieve 1.5*10<2> / ml; and the composite agent has characteristics of low use amount, no phosphorus, strong scale inhibiting capacity, good corrosion inhibiting performance, excellent sterilizing effect, and long lasting time.

The invention relates to a high-stability compound chlorhexidine iodohydrin solution. The high-stability compound chlorhexidine iodohydrin solution comprises the following components in parts by weight: 0.2-1 part of 10% of PVPI (Polyvinylpyrrolidone Iodine), 0.1-1 part of chlorhexidine acetate, 0.01-0.23 part of iodine, 50-70 parts of ethanol, 0.01-0.3 part of KI (Potassium Iodide), 0.1-2 parts of surfactant, 0.1-2 parts of humectants and 29.36-42.69 parts of water, wherein the pH value of the solution is regulated to 2-4 by phosphoric acid. The invention further relates to a preparation method of the high-stability compound chlorhexidine iodohydrin solution. The high-stability compound chlorhexidine iodohydrin solution disclosed by the invention is delicate in design, broad-spectrum in sterilizing effect, quick to become effective, capable of preventing drug-resistance bacteria from generating, quick to dry, more stable and longer in continuous sterilizing time, so that not only can effective content of sterilizing agent iodine in the product be satisfied, but also the iodine loss is reduced and the cost is lowered. Meanwhile, the high-stability compound chlorhexidine iodohydrin solution is capable of enabling the product to be more stable without stained yellow and capable of forming a protective film at the periphery of the wound without causing local infection, easy to clean and suitable for large-scale popularization and application.

The invention discloses a phosphorus-free water treatment agent composition. The composition contains a benzamide bactericide, a sulfonic group-containing phosphorus-free copolymer and a corrosion inhibitor, and the corrosion inhibitor can be one or more of borate, gluconate and silicate. The invention also discloses an application of the phosphorus-free water treatment agent composition in water treatment. A result of evaluation of the scale inhibition, corrosion inhibition and sterilization performances of the phosphorus-free water treatment agent composition in water treatment shows that the phosphorus-free water treatment agent composition has high calcium carbonate scale inhibition rate, high zinc scale inhibition rate, high sterilization rate and low carbon steel sheet corrosion rate on the premise that no phosphorus treatment agents are contained. The phosphorus-free water treatment agent has the advantages of environmental protection and excellent water treatment effect.
