Purifying treatment device used for high-salinity and high-alkali sewage

Abstract

The invention discloses a purifying treatment device used for high-salinity and high-alkali sewage. The purifying treatment device comprises a crystalizing chamber, a spiral centrifugal chamber, a filtering and absorbing chamber, an electrolyzing chamber and a neutral reaction chamber. A grit filtering layer, an organism filtering layer and an activated carbon adsorption layer are arranged inside the filtering and absorbing chamber sequentially from top to bottom. The electrolyzing chamber is positioned behind the filtering and absorbing chamber. A conduit arranged at the bottom end of the filtering and absorbing chamber is connected with the electrolyzing chamber, liquid is supplied to an electric appliance from the top end of the electrolyzing chamber, and a positive electrode and a negative electrode are respectively arranged inside the electrolyzing chamber. The neutral reaction chamber is positioned behind the electrolyzing chamber, a conduit arranged at the bottom end of the electrolyzing chamber is connected with the neutral reaction chamber, and an acid liquor box and an alkali liquor box are arranged on two sides of the neutral reaction chamber respectively. The purifying treatment device used for the high-salinity and high-alkali sewage has the advantages that soluble substances and insoluble substances in the sewage are treated separately, sewage treatment efficiency is improved greatly, and sewage treatment effect can be guaranteed by means of three treatment manners including biological decomposition, chemical reaction and physical absorption.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a purification treatment device for high-salt alkaline sewage. Background technique [0002] High-salt alkaline sewage has always been a difficult point in the field of sewage treatment. The pollutants in sewage have high concentration and high toxicity, which have poisonous and inhibitory effects on water treatment microorganisms. Many technical processes are difficult to meet the standards. Even if a small number of technical means meet the standards, the treatment cost higher. Wastewater chemical treatment is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer; however, a large amount of chemical reaction substances are required in the process of treatment , In the process of treating sewage, other pollution problems have arisen, the purpose...
