Embodiment

[0036] A certain salinization plant used brackish water as industrial cooling circulating water (adopting three-dose method to process) before, and now local facilities are adopting the method trial operation of the present invention, and the operating procedures are as follows:

[0037] 1. The factory is located on the original calcium chloride water. Originally, fresh water was used to flush toilets. However, due to the high water level in the shallow underground water layer in this area, the sewer network system leaked, resulting in the drainage water quality becoming brackish water. The brackish water contains bath water, canteen water, workshop flushing water and septic tank water. After treatment, the effluent reaches the water quality standard and is used as supplementary water for the cooling circulating water storage tank.

[0038] 2. The main parameters of domestic sewage treatment process are as follows:

[0039] Capacity: 200m 3 / day,

[0040] Hydraulic retention...

Abstract

The process of treating brackish water for use as industrial circular cooling water includes the following steps: 1. cleaning apparatus with corrosion and scaling in the cooling system with detergentand draining the treated waste water to domestic sewage treating system; 2. storing brackish water in landscape pond for natural settling; 3. taking the upper layer of clear water from the settling pond, oxidizing with active carbon and ozone, sterilizing, killing algae, decomposing organic matter and using as the circular cooling water source; 4. treating sewage of the step 1 for replenishing thecircular cooling water; 5. filtering, detecting and replenishing ozone before the water is replenished to the cooling system; and 6. circulating the cooling water. The present invention has the functions of saving water and protecting water source.

Description

technical field [0001] The invention provides a treatment method for using brackish water as industrial circulating cooling water. The method is to use ozone instead of adding corrosion inhibitors, scale inhibitors and bactericidal algicides to solve the problems of system corrosion prevention, scaling, and sterilization. , Algae killing technology. Background technique [0002] my country is a water-deficient country and is listed as one of the 13 poorest water-poor countries by the United Nations. Coupled with the uneven spatio-temporal distribution of freshwater resources, uneven population distribution and social development in China, freshwater resources are in serious shortage in some areas. According to statistics, at present, about 80% of urban water is industrial water, and about 80% of industrial water is industrial cooling water. Using brackish water as industrial cooling water instead of fresh water as industrial water is one of the important ways to solve the ...
