Starfish-shaped biological processor

Abstract

A starfish-shaped biological processor is used for landfill leachate, wastewater treatment plant upgrading, township sewage treatment, smelly water, and governance on polluted rivers and lakes. The main body structure is stainless steel, and the aeration diaphragm is made of a high-molecular corrosion-resistant material. A bionic technology is adopted in the structure, which is similar to starfish in shape; and the processor comprises a central device, eight aeration diaphragms and four supporting claws. The central device comprises a thorough cylindrical venturi drainage tube, a perforated closed square tubes with one short corner and four outlet tubes connected with the square tubes and in symmetrical distribution; the ends of the four outlet tubes are respectively provided with two branch tubes; each branch tube outlet is provided with an aeration diaphragm, and the diameter of the pore on the aeration diaphragm is less than the diameter of the pore on the closed aperture square tubes; and the four supporting claws comprise an air inlet pipe and three supporting legs, which are uniformly distributed in the periphery of the venturi drainage tube.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a biological processor used for treatment of garbage leachate, upgrading of sewage treatment plants, township sewage, black and odorous water bodies, and polluted rivers and lakes. Background technique [0002] The traditional disc aerator needs to be connected with a fixed gas pipeline and arranged at the bottom of the aeration tank. The main problems of this traditional aeration device are: first, the pipeline is complex and the auxiliary equipment is bulky and needs to be built separately The fan room increases civil construction costs and land occupation, and the aerator cannot be moved portablely; second, the traditional aerator cannot form a gradient distribution of microbial communities around its treatment area due to its internal mechanism of aeration, and cannot be used for ecological restoration Thirdly, the fixed and rigid installation mode makes the traditional aerators un...

Problems solved by technology

[0002] The traditional disc aerator needs to be connected with a fixed gas pipeline and arranged at the bottom of the aeration tank. The main problems of this traditional aeration device are: first, the pipeline is complex and the auxiliary equipment is bulky and needs to be built separately The fan room increases civil construction costs and land occupation, and the aerator cannot be moved portablely; second, the traditional aerator cannot form a gradient distribution of microbial communities around its treatment area due to its internal mechanism of aeration, and cannot be used for ecological restoration Thirdly, the fixed and rigid installation mode makes the traditional aerators unable to be used for the treatment of rivers and black and odorous water bodies; fourthly, once the traditional aerators used in sewage treatment plants are damaged, the water stations must be shut down and emptied before they can be used. Maintenance, the upgrade of the original old water field cannot be completed without the sewage field being shut down
