Treatment system for thermal power plant circulating water blowdown water

Abstract

Belonging to the technical field of reclaimed water reuse, the invention discloses a treatment system for thermal power plant circulating water blowdown water. The treatment system is comprised of a make-up water system of circulating cooling water and a blowdown water pipeline of circulating cooling water. A circulating cooling water pool of the make-up water system of circulating cooling water is in connection with a buffer pool of the make-up water system of circulating cooling water through the blowdown water pipeline of circulating cooling water. According to the invention, the blowdown water of circulating cooling water is led into the reclaimed water buffer pool of the make-up water system of circulating cooling water, and is treated together with the reclaimed water from a municipal sewage treatment plant, so that a set of blowdown water treatment system of circulating cooling water can be saved, with the saved treatment system composed of a circulating water blowdown water buffer pool, a circulating water blowdown water lifting pump, a circulating water blowdown water lime coagulation and clarification pool, a circulating water blowdown water filtering pool and other equipment. Therefore, the system provided in the invention reduces the initial investment cost of a thermal power plant, saves land occupation, and is convenient for centralized arrangement, as well as centralized maintenance and management.

Description

technical field [0001] The invention relates to the technical field of reclaimed water reuse, in particular to a thermal power plant circulating water sewage treatment system. Background technique [0002] Thermal power plants are major users of industrial water and wastewater discharge. In the current situation of water shortage, some cities have begun to reduce the supply of tap water to thermal power plants or limit their use of groundwater. Therefore, in order to ensure the safety of units and water requirements and reduce environmental pollution, power plants have begun to use urban reclaimed water through depth After treatment, make boiler make-up water. Circulating water and sewage is the main water consumption part of thermal power plants, and the reuse of sewage is one of the effective ways to alleviate the crisis of water resources and protect the water environment. [0003] The distribution of water resources in the north and south of my country is uneven. With ...
