Description

Integrated high-efficiency energy-saving sewage treatment device

Technical Field

The utility model belongs to the technical field of sewage treatment, and particularly relates to an integrated efficient energy-saving sewage treatment device.

Background

The sewage treatment technology is generally divided into a physical method, a chemical method, a biological method and the like, wherein an activated sludge method in the traditional biological treatment method is a treatment technology with wider application. The core treatment equipment of the traditional activated sludge method comprises an aeration tank, an activated sludge reflux system, an aeration system and other main systems.

Along with the continuous improvement of sewage treatment technology, the traditional activated sludge method gradually derives a treatment technology with simpler treatment technology, wherein the oxidation ditch technology belongs to one deformation of an activated sludge process system. The traditional oxidation ditch process system has the processes of degradation of organic pollutants, mud-water separation, sludge stabilization and the like, and the main devices of the system comprise aeration and a propeller.

The aeration is used as a core treatment process, compressed air is firstly introduced into mixed liquor of an aeration tank in the form of tiny bubbles through an air diffusion device, so that the mixed liquor is subjected to normal and full activated sludge reaction, organic pollutants in sewage are degraded and removed by activated sludge microorganisms, the sewage is purified, the activated sludge microorganisms are multiplied, and the activated sludge body is increased. Generally, the mixed solution after the reaction of the activated sludge flows out from the other end of the aeration tank, enters the secondary sedimentation tank, is subjected to solid-liquid separation, and is separated from sewage by sedimentation to obtain purified and clarified sewage which is used as a treated water discharge system. And discharging the precipitated activated sludge from the secondary sedimentation tank through concentration, wherein a part of the precipitated activated sludge is used as inoculated sludge, the inoculated sludge is returned to the head end of the aeration tank through a sludge return system, and the rest of the precipitated activated sludge is used as residual sludge discharge system.

The propeller is used as a treatment device of the other core in the oxidation ditch process system and is mainly used for pushing the mixed liquor in the ditch to keep a certain flow velocity to flow forwards, so that the organic substrate and the activated sludge microorganism in the mixed liquor can be fully contacted with each other at a high frequency.

On the premise of urban and rural land use of the current size and the price, how to use an integrated space structure to complete high-efficiency sewage treatment becomes a difficult problem to be solved.

Aiming at the prior oxidation ditch treatment device, the utility model of Li Xiaonan is an integrated oxidation ditch for decentralized domestic sewage treatment, which is disclosed in the patent number CN217676991U, and comprises an oxidation ditch body, a transmission structure, an aeration structure, an exhaust structure communicated with the aeration structure, a impurity removing structure and a collecting structure. The oxidation ditch body comprises an aerobic zone, an anoxic zone and a sedimentation zone. The exhaust structure can enlarge the area of aeration operation, and the impurity removing structure can remove larger impurities.

The Liang Xiaoxian patent number is CN217437861U, and a circulating oxidation ditch with an automatic sewage backflow function is internally provided with a stirring component and a defoaming component, so that the blockage of a water pump during operation is avoided.

Wang Jiajun U, and the like, mainly by arranging a plurality of liftable denitrification biological filler module assemblies, the oxidation ditch treatment device and the wastewater treatment system realize good effluent quality under the conditions of no additional structures and no increase of occupied space.

Wu Xianjin U.S. patent No. CN217230355U, through the end-to-end connection of the reflux area to form a circulating flow, the maintenance and the unmanned intervention of the sewage treatment plant are realized without stopping production all the year round, and the guarantee of the stable and standard discharge of the water discharged all the year round of the sewage treatment plant is further enhanced.

Among them, li Xiaonan utility model's integrated oxidation ditch for decentralized domestic sewage treatment has more structures. When a certain structure of the integrated oxidation ditch breaks down, the treatment effect of the sewage treatment system can be reduced due to untimely maintenance.

Additional components in the Liang Xiaoxian cyclic oxidation ditch can generate additional electricity consumption, so that the treatment cost is increased.

Wang Jiajun and the biological filler module in the wastewater treatment system, the problems of blockage, uneven film formation and the like are caused with the increase of the operation time, and the treatment effect is reduced.

Wu Xianjin and the like are easy to cause the problems of too much sludge blocking the water pump and the like.

Because the rural usable floor area is more loose, can adopt oxidation ditch to handle domestic sewage, oxidation ditch's simple structure is effectual to sewage treatment. Because the management level in rural areas is relatively low, the coping capability of sewage treatment technology is relatively weak, the structure is complex, and the like, certain difficulty is caused to operation, and the problem that the water quality of the effluent of the system is reduced due to untimely solution is solved. The sedimentation area is added in the oxidation ditch, so that the blockage of a water pump and an aeration disc caused by excessive slurry in sewage can be avoided, a large amount of sludge attached to the surface of a flow pushing device can be avoided, and structures in a sewage treatment system can be reduced. The floor area of the planar oxidation ditch is larger, and the floor area of the vertical oxidation ditch can be reduced while the treatment effect is maintained.
