Description

Incinerator for treating wastewater containing high organic salt

Technical Field

Background

Along with the large scale, centralized and large-scale chemical industry, more and more chemical parks need to carry out wastewater treatment. For different wastewater components, biological, chemical and physical methods are generally adopted for treatment.

The physical method mainly utilizes physical action to separate insoluble substances in sewage; the chemical method mainly utilizes chemical reaction, chemical substances are added into the wastewater, and harmless substances or colloid are generated after the reaction; the biological method mainly utilizes the metabolism function of microorganisms to decompose and oxidize organic matters into stable inorganic matters. Incineration is one of the chemical methods that utilizes high temperature combustion of combustible or inert residual waste, leaving behind dust and non-combustible materials.

Foreign research shows that the high-concentration wastewater with COD more than 100000ml/L and heat value more than 4.1868 KJ/kg is more reasonable than other methods by using an incineration method. Such as: the high-concentration salt-containing dye wastewater contains high-concentration inorganic salt and a considerable amount of soluble and non-degradable organic matters, is difficult to remove by a physical method and a biological method, and is the best choice by an incineration method.
