Problems solved by technology

Therefore, in order to reduce scaling and pipeline corrosion, it is often necessary to treat the supplementary water of cooling water. During the water treatment process, it is often necessary to introduce disinfectants for disinfection and sterilization. On the one hand, it will also affect the water quality, causing corrosion of the air-conditioning circulating cooling water system and causing scale

Abstract

The invention discloses a water treatment method for make-up water of cooling water of an air conditioner, which comprises the following steps: S1, introducing water to be treated into a comprehensive regulating tank, carrying out water quality equalization, and then carrying out filtering treatment to obtain first effluent water; s2, performing cation exchange treatment and anion exchange treatment on the first effluent to obtain second effluent; s3, a disinfectant is put into the second effluent, and third effluent is obtained after treatment; and S4, carrying out adsorption treatment on the third outlet water by taking modified zeolite as an adsorbent, then conveying the third outlet water to a water supplementing water tank, and supplying water to an air conditioner cooling tower by the water supplementing water tank. By adopting the method, the water replenishing quality can be ensured, and the problems of corrosion and scaling can be reduced.

Description

technical field [0001] The invention relates to the technical field of air-conditioning water supply systems, and in particular, to a water treatment method for air-conditioning cooling water supplementary water. Background technique [0002] At present, the cooling water of the central air-conditioning water system is mostly an open system. The cooling water is stored in the cooling tower. The cooling water in the cooling tower is continuously evaporated and concentrated. The heat exchange efficiency of the host decreases, and the daily performance is as follows: after the host is turned on, the temperature cannot be lowered to a suitable temperature in a short period of time; the working time of the host is prolonged, the number of boots increases; the host alarms and other faults. Therefore, it is necessary to replenish water to the cooling tower in time. In the process of replenishment, tap water is often used to replenish water. However, the quality of tap water varies ...
