Novel rotary drum type hydraulic-biological algae-removing device

Abstract

The invention discloses a novel rotary drum type hydraulic-biological algae-removing device which comprises algae-removing biological incubation chambers, a hydraulic guide wheel, a floating barrel, a rotating shaft and a fixed bracket, wherein the rotating shaft is arranged on the fixed bracket; the rotating shaft passes through the floating barrel and is fixedly connected with the floating barrel; a plurality of algae-removing biological incubation chambers are arranged around the floating barrel; the algae-removing biological incubation chambers and the hydraulic guide wheel are filled with carriers; the hydraulic guide wheel is arranged at the periphery of the algae-removing biological incubation chambers; water through holes are formed between the algae-removing biological incubation chambers as well as between the algae-removing biological incubation chambers and the hydraulic guide wheel; the hydraulic guide wheel integrally adopts a V-shaped cavity structure. The novel rotary drum type hydraulic-biological algae-removing device can transform kinetic energy which enables water to flow into the kinetic energy of the novel rotary drum type hydraulic-biological algae-removing device, can stir a water layer, fulfills the aims of intercepting algae and increasing dissolved oxygen in water, and is particularly suitable for pollution treatment of a flowing landscape water body with few biocenoses.

Description

technical field [0001] The invention relates to a biological algae remover, in particular to a novel drum-type hydraulic biological algae remover, which belongs to the technical field of water treatment. Background technique [0002] Aerobic pollutants are one of the most important pollutants in water bodies. Under the action of microorganisms, oxygen-consuming pollutants decompose in water bodies and consume dissolved oxygen in water bodies at the same time. When the consumption rate of dissolved oxygen in water is greater than its oxygen enrichment rate, the aerobic reaction rate of pollutants will decrease, and gradually transform from aerobic reaction to anaerobic reaction, and ammonia, hydrogen sulfide, etc. will be produced during the anaerobic reaction. Malodorous gas, which is also the main reason why many water bodies turn black and stink. Therefore, in order to control the black and odor problem of water body, it is necessary to ensure that there is sufficient dis...

Problems solved by technology

Due to the poor fluidity in closed and semi-closed water bodies and the slow exchange rate with external water resources, the exogenous pollutants entering the water body and the endogenous pollutants produced in the water body can only rely on the self-purification of the water body to achieve the degradation of pollutants. Once the total amount of pollutants exceeds the self-purification capacity of the water body, the water quality will deteriorate, leading to algal blooms, which will seriously affect the use of the water body.
