Problems solved by technology

Biological method is a method of treating wastewater by using the metabolism and reproduction of microorganisms themselves. However, heavy metals and other substances in high-salt wastewater will destroy the life structure of microorganisms, inhibit their growth and reproduction, and even lead to cell inactivation.
The chemical method is to deal with chemicals, which is costly and will cause secondary pollution
The physical method separates some pollutants from the wastewater system by physical means such as adsorption, flocculation, coagulation, etc. Compared with the above two methods, this method is more feasible, but there are still the following problems to be solved: ① existing technology adsorption or After filtration, it needs desorption or backwashing, so it can only run intermittently. Usually, several parallel processes are set to run alternately. The essence is still intermittent operation, which increases the initial investment and operating costs; ②The quality of the adsorbent is large, which increases the total weight of the equipment. Thereby increasing the operating costs such as power consumption; ③The existing adsorbent has insufficient adsorption effect
As a new type of lightweight material, hydrogel has a good adsorption effect on pollutants, but its application in the field of high-salt wastewater treatment has rarely been reported.

Abstract

The invention provides a drum-type bidirectional flow purification system for high-salinity wastewater. The drum-type bidirectional flow purification system comprises a purification system and a pipeline system nested in the purification system; the purification system comprises six partition plates, a purification area of a hollow cylindrical structure, a cylindrical water distribution bin located at the axis of the purification area, a rotating shaft connected with the six partition plates, a motor driving the rotating shaft to rotate, a fixing support fixedly connected with the motor and used for supporting the system, and a water storage tank; the six partition plates are uniformly distributed in a purification area of the purification system, and the purification area is axially and uniformly divided into six fan-shaped independent purification areas; and the six independent purification areas are filled with hydrogel materials with a water purification effect. According to the system provided by the invention, the motor is utilized to drive the rotating shaft so as to drive each independent purification area in the purification system to rotate at regular time, so that sequencing batch work of each independent purification area is realized, meanwhile, the effect of turning over the filler can be achieved, the filler is convenient to clean, and continuous treatment of high-salinity wastewater can be realized.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a drum type bidirectional flow purification system for high-salt wastewater. Background technique [0002] As the main component of industrial production wastewater, high-salt wastewater has become a major environmental protection problem faced by industrial development and wastewater treatment at the present stage due to its large discharge volume and high difficulty in treatment. Substandard discharge of high-salt wastewater will not only waste salt and water resources, but also cause serious environmental pollution. Since salinity is an important environmental factor in the water environment, it has a direct or indirect impact on aquatic organisms, growth and reproduction. When the salinity of the water environment increases sharply, it will lead to the osmotic balance between the aquatic species and its living environment, causing dehydration of...
