Industrial wastewater physicochemical treatment agent and application thereof

Abstract

The invention relates to an industrial wastewater physicochemical treatment agent and an application thereof. A physicochemical treatment material HB-F001, a physicochemical treatment oxidizing and adsorbing agent HB-F002 and a physicochemical treatment solid-liquid separating agent HB-F003 are applied to industrial wastewater treatment through stirring, adsorbing, reacting, separating, circulating and the like. The industrial wastewater physicochemical treatment agent solves the problems that the iron-carbon bed hardening subsequent treatment efficiency is low, electricity consumption is high, more materials are consumed and more solid wastes are generated during electrolysis, secondary pollution is caused by plenty of salt generated by repeatedly adjusting the Fenton treatment pH value, the application ranges of photocatalysis and ultrasonic waves are limited, ozone is high in electricity consumption and high in investment, ozone is generated unstably and the treatment effects are unstable, and solves the problems of high treatment cost of a wet oxidation process and safety. The industrial wastewater physicochemical treatment agent substantially increases the wastewater pollutant control and pollution factor removal rate, satisfies reuse water biochemical treatment conditions and treatment cost, is sustainable and stable, avoids secondary pollution, is low in cost, has quite high application values, and really achieves the effect of environmental protection.

Description

technical field [0001] The invention relates to industrial wastewater treatment, in particular to a physical and chemical treatment agent for industrial wastewater and its application. Background technique [0002] For the physical and chemical treatment of industrial wastewater, iron-carbon bed, electrolysis, Fenton, photocatalysis, ultrasonic, ozone, and wet oxidation are basically used (due to the high cost of treatment, small amount of water to be treated and safety issues, enterprises do not use this method at present. Technology), etc., add inorganic polymer PAC and another type of organic polymer CPAM or APAM+ biochemical treatment of anaerobic (or hydrolytic acidification) + aerobic + secondary sedimentation and then effluent. This treatment process is currently the most advanced in the country, but it cannot achieve stable operation or stable reuse and discharge in terms of COD, chroma, and safety. In addition, the processing cost is 30-150 yuan / m 3 Not wait, the ...

Problems solved by technology

This treatment process is currently the most advanced in China, but it cannot achieve stable operation or stable compliance with reuse and discharge in terms of COD, chroma, and safety.

In addition, the processing cost is 30-150 yuan/m 3 No wait, the current industrial tap water is 3 yuan/m 3 The cost is too high for the enterprise to accept, and even if such a high cost is spent, the water quality and biochemical requirements of the enterprise cannot be met, and the discharge standards formulated by the country or localities cannot be solved. More importantly, water resources and polluted environment
