High-efficiency combined purification system for algae-containing wastewater treatment

Abstract

The invention discloses a high-efficiency combined purification system for algae-containing wastewater treatment, which comprises a purification container. The system is characterized in that the purification container is sequentially composed of a filter chamber (1), a plasma reaction chamber (2), a flocculating chamber (3) and a water collection chamber (4) from bottom to top, wherein a filter screen is arranged between the filter chamber (1) and the plasma reaction chamber (2); a screen layer is arranged between the plasma reaction chamber and flocculating chamber; the purification container is provided with a water inlet at the filter chamber, and also provided with a water outlet at the water collection chamber. By adopting the integrated combination technique, the system has the advantages of small occupied area, high algae removal efficiency, low reagent consumption and favorable quality of effluent water. By adopting the plasma discharge for oxidization and algae removal, the system greatly lowers the emission of malodorous gas, and reduces the pollution of the malodorous gas to the atmospheric environment. The system has high algae removal rate and favorable removal effect for SS (suspended sediment) and CODcr (chemical oxygen demand).

Description

technical field [0001] The invention relates to algae removal technology, which belongs to the technical field of environmental protection, in particular to a high-efficiency composite purification system suitable for the treatment of algae-containing wastewater. Background technique [0002] In recent years, with the rapid development of social economy, the discharge of a large number of chemical substances has made the eutrophication of the water body increasingly serious, and the algae blooms in large numbers, resulting in a decrease in water transparency, a decrease in dissolved oxygen, and a continuous deterioration of water quality. The bottom of the water body is hypoxic, resulting in Some fish suffocate to death. Among them, some algae can produce algal toxins, which also pose a threat to the safety of drinking water for aquatic organisms and humans and animals. Some algae can produce peculiar smells, which affect the living environment of surrounding residents. [...

Problems solved by technology

Experiments and practice have proved that only relying on a single method, the effect of governance is often unsatisfactory

For example, the direct filtration algae removal method, although the algae removal rate is high, but the removal of nitrogen, turbidity, color, and COD Cr Poor; adding chemical reagents to remove algae will bring secondary pollution, and it is not conducive to large-scale application; although the air flotation method also has a high algae removal rate, it also has its disadvantages: the scum of air flotation is difficult to handle, The air flotation pool usually emits a bad smell, resulting in a poor surrounding environment. In order to ensure the effect of the air flotation, pre-chlorination is required before the air flotation, but this will endanger the safety of drinking water
