High-salinity wastewater treatment system coupling flow storage purification and flow expansion flushing

Abstract

The invention provides a high-salinity wastewater treatment system coupling flow storage purification and flow expansion flushing. The system comprises a hydrogel loading system and a flow storage different-direction water inlet and outlet system; the hydrogel loading system comprises six partition plates, a wastewater treatment area, a water distribution bin, a rotating shaft, a driving motor and a fixed bracket; the wastewater treatment area is axially and uniformly divided into six fan-shaped independent treatment areas by the six partition plates; the six independent treatment areas are filled with hydrogel materials with the water purification effect, the hydrogel materials permeate into the independent treatment areas one by one through high-salinity wastewater inlet meshes in the surfaces of the wastewater treatment areas, and purified high-salinity wastewater is discharged through a wastewater cleaning water outlet pipe with the same water inlet direction as a cleaning filler water distribution pipe; and then rotating is conducted to a vertically downward six o'clock direction to clean the independent treatment area. According to the system provided by the invention, independent and non-influencing operation of each independent processing area element is realized by utilizing a special structure, the controllability is high, the processing complexity is reduced, and the operation cost and the human input are further reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a high-salt wastewater treatment system coupled with flow storage purification and expansion flow washing. 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. [0003] 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 liv...

AI Technical Summary

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.
