The invention relates to an anti-clogging aerator which comprises an upper bubble rectifying device, a middle bubble cutting device, a lower bubble cutting device and an air intake component, wherein the upper bubble rectifying device comprises a cowling, a rectifying plate and a funneled cowling transitional connection casing; the middle bubble cutting device comprises a middle casing, a middle cutting plate and a middle funneled transitional connection casing; the lower bubble cutting device comprises a lower casing and a lower cutting plate; the air intake component comprises an air inlet pipe, a cover body and a baffle plate. According to the invention, gas is smashed into bubbles through cutting holes in the gas and liquid mixing process, after being cut at each stage, the bubbles become smaller in size and are increased in number, meanwhile, the gas flow rate is lowered so as to enlarge the service area of the bubbles. Blowdown holes are formed in the lower casing and the lower part of the cover body, the cutting holes are formed in the cutting plates and are not blocked easily or required to be cleaned, and the use is not influenced even the cutting plates scale slightly. The anti-clogging aerator is simple in structure and convenient to operate; procedures for cleaning the aerator frequently are reduced, and the production efficiency is improved.

An airlift membrane reactor with external ring flow is composed of main body, airlift pipe, inorganic membrane element, and axial aerating head. Said inorganic membrane used as radial gas distributor and separator is sealed in external-circulation airlift pipe and communicated with compressed air source and vacuum system for continuous aeration and reaction. Its aerating efficiency and stirring efficiency can be respectively regulated.

The invention discloses an urban river ecological remediation system based on waterfront movement upper limb traction device aeration. The urban river ecological remediation system is constituted by connecting an energy transmitting and converting unit, an upper limb traction unit, a microporous aeration unit and a landscape plant restoration unit in sequence, wherein the energy transmitting and converting unit is composed of an outer cylinder, a middle cover, an inner cylinder, a packing cup, a steel ball one-way valve, a hollow base and an inverted-cross-shaped support, the upper limb traction unit is composed of a dual-track pulley, an upper steel wire rope, a lower steel wire rope, a spring fastener, a metal ring and an upper limb traction device, the microporous aeration unit is composed of a three-way unit, an air delivery pipe, an air stopping valve and a microporous aeration pipe, and the landscape plant restoration unit is composed of a fixed rotary shaft, a connecting ring, emergent aquatic plants, a filler string net, a cylindroid frame and a weaving net cover. Mechanical energy generated when the upper limb traction device is utilized is converted into mechanical energyof an aeration device, thus the dissolved content of oxygen in water is increased, and through combination of an ecological remediation floating floor which can move with water current, eutrophic urban rivers are remedied, and the urban river ecological remediation system has the advantages of being environmentally friendly, attractive, simple in structure, economical and practical.
