Embodiment 1

[0032] In this example, a kind of green environment-friendly chemical agent for circulating water treatment, the weight percentage of its components is as follows: 25 parts of scale inhibitor, 5 parts of flocculant, 18 parts of corrosion inhibitor, 1 part of defoamer and cleaning agent 10 parts, the rest is deionized water, a total of 100 parts.

[0033] Wherein, the scale inhibitor is composed of polyaspartic acid, acrylic acid and sodium benzotriazole in a mass ratio of 8:5:1.

[0034] Wherein, the flocculant is composed of polysilicate aluminum sulfate and aluminum sulfate with a mass ratio of 5:3.

[0035] Wherein, the corrosion inhibitor is composed of triazine polycarboxylic acid and sodium benzotriazole in a mass ratio of 1:1.

[0036] Wherein, the defoamer is a polyether modified silicone oil defoamer.

[0037] Wherein, the cleaning agent is ethylenediaminetetraacetic acid.

[0038] Wherein, the preparation method of the green environmental protection agent is proce...

Abstract

The invention relates to the technical field of water treatment, in particular to an environment-friendly agent for circulating water treatment. The environment-friendly agent comprises the followingcomponents in parts by weight: 25-33 parts of a scale inhibitor, 5-10 parts of a flocculating agent, 18-20 parts of a corrosion inhibitor, 1-5 parts of a defoaming agent, 10-15 parts of a cleaning agent and the balance of deionized water. The invention aims to provide the environment-friendly agent for circulating water treatment. The agent can achieve better scale inhibition and corrosion inhibition effects in the water treatment process.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a green environmental protection agent for circulating water treatment. Background technique [0002] With the rapid development of the world economy, the global water resource shortage and water pollution problems have been seriously faced by people. Domestic urban industrial water accounts for about 80% of the total urban water consumption, while industrial cooling water consumption accounts for about 2 / 3 of industrial water consumption, and cooling water consumption in the petroleum and petrochemical industry accounts for a larger proportion, accounting for about 2 / 3 of industrial water consumption. 80% -90% of that, so saving industrial cooling water is very necessary. Reasonable use of water treatment chemicals to increase the concentration of circulating water not only solves the energy problem of energy saving and water conservation, but also solves the environmen...
