Integrated Natural Circulation Baffled Reactor

Abstract

The invention provides an integrated natural circulating and baffling reactor, which comprises an agent-water mixing device, a reaction tank and an aeration device, wherein the reaction tank comprises a catalytic oxidation tank, an anaerobic tank and an aerobic tank which are arranged sequentially, the catalytic oxidation tank is connected with the rear end of a tube-type mixer, and up-and-down curved baffling channels are formed between the catalytic oxidation tank, anaerobic tank and aerobic tank; filler layers are separately arranged in the catalytic oxidation tank, anaerobic tank and aerobic tank and used for the catalytic oxidation, anaerobic and aerobic reactions; and wastewater is introduced into the reaction tank after being mixed with added hydrogen peroxide through a wastewater inflow pipe, and under the mating action of the aeration device, the wastewater is sequentially treated by catalytic oxidation, anaerobic and aerobic treatment and then discharged. In the reactor provided by the invention, a natural circulating and baffling manner is adopted and the catalytic oxidation, anaerobic and aerobic processes are integrated; and the reactor has the characteristics of compact structure, small occupation area, less energy consumption, low investment, strong shock load resisting capability, low operating cost and stable treatment effect.

Description

[0001] technical field [0002] The invention relates to a wastewater treatment device, which is especially suitable for treating organic wastewater that is difficult to biochemically degrade. [0003] Background technique [0004] With the development of industries such as medicine, chemical industry, pesticide and printing and dyeing, the amount and types of refractory organic substances in industrial wastewater are increasing day by day. These wastewater are directly discharged into rivers, lakes and seas without treatment, causing serious environmental pollution and ecological damage. Humanity's own health also poses a serious threat. Pharmaceutical, chemical, pesticide and other wastewater is not only toxic and harmful, but also complex in composition, generally composed of aromatic compounds, stable in structure, poor in biochemical properties, and potentially toxic. The treatment of refractory organic wastewater has become one of the hotspots and difficulties in the...

Problems solved by technology

[0006] These organic wastewater treatment technologies and devices generally have disadvantages such as high operating costs, high energy consumption, long action time, poor impact load resistance, large dosage, and large sludge production.

In addition, some advanced advanced oxidation technologies have high requirements for equipment and large investment, and most of them are still in the laboratory stage, so the practicability is poor
