Industrial waste gas, wastewater and circular cooling water physical and chemical treatment system

Abstract

The invention discloses an industrial waste gas, wastewater and circular cooling water physical and chemical treatment system. The system comprises a mixed water tank, a filtering device, a circulation water tank and a heat exchanger, pipelines of an industrial water source, waste gas and wastewater are connected to the mixed water tank, the mixed water tank is connected to the front end of the filtering device through a pipeline, outflow water at the rear end of the filtering device is connected to the water inlet end of the circulation water tank, the water outlet end of the circulation water tank is connected to the front end of the heat exchanger, the heat exchanger is circularly connected to the circulation water tank through the first water outlet end behind a water return pipeline,and the second water outlet end is connected to the front end of the filtering device, wherein a water treating device is arranged inside the circulation water tank and / or the water inlet and outlet ends of the circulation water tank, and the water inlet and outlet ends of the circulation water tank are provided with an oxidizing agent injecting device and / or an environment-friendly additive injection device. Wastewater and waste gas can be treated at the same time, the outflow water quality is pure, the system stability is high, the safe and efficient working environment can be provided withthe lowest cost, and discharge of medicament, wastewater, CO2 and the like is reduced.

Description

technical field [0001] This case belongs to the technical field of waste treatment systems, and mainly involves a physical and chemical treatment system for industrial waste gas, waste water, and circulating cooling water. Background technique [0002] Water is the source of life and a necessary condition for the existence of life and economic development. However, with the rapid economic development and population growth, the quality of water resources continues to decline, the water environment continues to deteriorate, and water shortages and accidents due to pollution continue to occur. It not only stops production of factories, reduces agricultural production or even fails to harvest, but also causes adverse social impact and large economic losses, which seriously threatens the sustainable development of society. Waste gas and waste water from industrial production are the main sources of pollution. Therefore, in order to Conserving water resources, protecting the envir...

AI Technical Summary

Problems solved by technology

[0003] The recycling of waste gas and waste water in the prior art can only achieve one kind of waste gas or waste water, and cannot realize the simultaneous recovery and treatment of waste gas and waste water, and the process of recycling will produce chemicals, waste water, CO 2 and other emissions, resulting in secondary pollution
