Problems solved by technology

Most of the water treatment chemicals currently on the market are phosphorus-containing and non-biodegradable, which are environmentally unacceptable pollutants; there are also some water treatment chemicals that are phosphorus-free and environmentally friendly, although these water treatment chemicals have no pollution. Phosphorus has the advantages of being environmentally friendly and biodegradable, but compared with the commonly used phosphorus-containing water treatment agents on the market, its scale inhibition performance is still low, which limits the practical application of these scale inhibitors; In technology, when chemical agents are used alone for scale inhibition, the amount of agents added is relatively high, the cost is high, and the impact of large amounts of agents on the environment is relatively large; if physical water treatment methods are used alone, such as electrostatic, magnetic field etc., the anti-scaling effect is not very good
However, there is no related technology that combines static electricity, magnetic field and chemical agents.

Abstract

The invention discloses a static, magnetic filed and chemical dosing united water treatment novel method. The method comprises the following steps: firstly, treating raw water by virtue of a static water processor for a period of time to obtain static water; in the process, carrying out static water treatment by using different static water treatment time, different water flows by the static water processor and different static voltages; and then, treating the static water by utilizing a water magnetizer, magnetizing the water by using different magnetizing time, different magnetizing water flows and different intensities of the magnetic fields, and then, adding different ESA / AMPS copolymers for scale inhibition test research to calcium carbonate and calcium phosphate. The scale inhibition rate of the ESA / AMPS copolymer obtained is the scale inhibition rate coordinated by static, magnetic filed and ESA / AMPS copolymers.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a new method for water treatment combined with static electricity, magnetic field and chemical dosing. Background technique [0002] There are two methods of industrial circulating cooling water treatment: chemical dosing and physical water treatment. Among industrial water treatment chemicals, scale inhibitors are commonly used in the largest amount, which is of great significance to prevent scale inhibition of equipment, reduce energy consumption, prolong equipment life, and ensure safe operation of equipment. Most of the water treatment chemicals currently on the market are phosphorus-containing and non-biodegradable, which are environmentally unacceptable pollutants; there are also some water treatment chemicals that are phosphorus-free and environmentally friendly, although these water treatment chemicals have no pollution. Phosphorus has the advantages ...
