A double-effect air flotation high-algae water treatment equipment and its treatment process

Abstract

The invention discloses a double-effect air-floatation algae-laden water treatment apparatus. A mixing reaction zone and an air-water contact room connected with a coagulation reaction zone are arranged in the front of a pool body, the opening at the upper portion of the air-water contact room is connected with a solid-liquid separation zone at the upper portion of the pool body, an electrolysis zone is arranged below the solid-liquid separation zone, a water collection zone is arranged below the electrolysis zone, a perforation water collection network is arranged in the water connection zone, the perforation water collection network is connected with an outfall sewer, and a mud connection bucket is arranged below the perforation water collection network. The water treatment technology integrates a dosing mixing reaction process with an air floatation process, integrates an dissolved air floatation process with an electrolysis air floatation process and integrates an air floatation treatment process with an electrode oxidation process, so the apparatus integrating the above three efficacies can greatly improve the treatment efficiency of algae-laden polluted source water; and the apparatus has the advantages of high treatment efficiency, operation and adjustment convenience, land occupation saving and low energy consumption, so the apparatus can be widely applied to various difficult industrial wastewater treatments.

Description

technical field [0001] The invention belongs to a water treatment process and equipment thereof, and specifically mainly refers to a double-effect air flotation high-algae water treatment equipment and a treatment process thereof. Background technique [0002] In recent years, the water quality of most lakes and reservoirs in my country has been deteriorating, and high algae occur frequently in spring and summer, and the number of algae in the water often reaches tens of millions / m 3 , even up to hundreds of millions / m 3 , The conventional treatment process of urban waterworks is greatly affected by this pollution, and the quality of effluent water is difficult to meet the standard. Therefore, a pretreatment process must be added before the conventional water treatment process to reduce the algae pollution load, reduce the dosage of algicides for conventional treatment, improve the treatment capacity of conventional processes, and eliminate the algal odor. Algae particles ...

AI Technical Summary

Problems solved by technology

But for tens of millions of algae / m 3 For the above polluted source water, the amount of residual algae remaining after the pressurized dissolved air flotation treatment is still considerable, and it is difficult to remove it by subsequent conventional treatment processes. Handling process is very unfavorable
