Blowdown treatment process for thermodynamic system of hot water boiler

Abstract

The invention discloses a blowdown treatment process for a thermodynamic system of a hot water boiler, and the specific manufacturing method comprises the following steps: S1, firstly, uniformly collecting gas generated in the hot water boiler, and then carrying out acid gas removal treatment; s2, carrying out secondary treatment on the waste gas, and carrying out a desulfurization process; s3, uniformly collecting the waste liquid generated by the hot water boiler, and performing acid pretreatment; s4, carrying out alkaline mixing treatment on the waste liquid, and collecting precipitates; and S5, carrying out biological treatment on the wastewater, and recycling available resources. By means of the method, waste gas and waste liquid generated by the hot water boiler can be collected and treated in a unified mode, dust in the waste gas and sulfide in the gas can be effectively reduced, acidification and alkalization treatment can be conducted in the waste liquid treatment process, more calcium and iron compounds can be precipitated and recycled, meanwhile, phosphorus can be treated through a biological method, and the injected ozone can be used for disinfection and sterilization treatment, so that the whole process is relatively comprehensive, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of environmental protection sewage discharge, in particular to a sewage discharge treatment process of a thermal system of a hot water boiler. Background technique [0002] Hot water boilers can be divided into electric hot water boilers, oil-fired hot water boilers, gas hot water boilers, coal-fired hot water boilers, etc. according to different fuels; , what we usually call "hot water boiler" refers to the normal pressure hot water boiler. Due to its safe operation, people mostly use this kind of normal pressure hot water boiler for bathing or heating. The hot water boiler mainly has two types: heating and bathing. use. The hot water boiler circulates the hot water in the thermal insulation water tank through the hot water circulation pump, and heats the hot water in the water tank repeatedly to achieve the purpose of bathing; the hot water boiler circulates the hot water in the heating pipe through the h...
