Abstract

The invention relates to a treatment system for boiler feedwater, the treatment system comprises an industrial wastewater discharge tank, a coagulation clarification tank, a coagulation chemical storage and dosing device, a No.1 water tank, a filter, an electric adsorption device, a No.2 water tank and a desalting unit. The coagulation clarification tank is connected to the No.1 water tank, the No.1 water tank is connected to the filter through a No.1 water pump, the clean water outlet of the filter is connected to the No.2 water tank through the electric adsorption device, and the No.2 watertank is connected to the desalting unit through a No.2 water pump. The coagulation chemical storage and dosing device is connected to the coagulation clarification tank, and the sewage outlets of thecoagulation clarification tank and the desalting unit are connected to the industrial wastewater discharge tank. The boiler feedwater utilizes the treatment system of ''coagulation clarification, filtration, electric adsorption device, desalting", cancels the processes of self-cleaning filter, ultrafiltration and reverse osmosis, and has the advantages of small occupied area, low device investmentand operation cost, less industrial wastewater generation and high automation degree.

Description

technical field [0001] The invention belongs to the technical field of industrial water treatment and relates to a treatment system for boiler feed water. Background technique [0002] The power industry is a basic industry of the national economy and an important energy industry. It is a large industrial water user and has great potential for water saving. Under the premise of ensuring the safe and economical operation of the unit, the comprehensive utilization of water resources should be actively carried out to achieve the goals of saving water and reducing emissions, reducing power generation costs, and protecting the ecological environment. In thermal power plants, industrial water mainly includes two parts, one part is circulating cooling water, which is mainly used for equipment cooling; the other part is boiler make-up water, which is mainly used to supplement the normal loss in the steam-water circulation of the thermal system. With the development of high-paramete...
