Example Embodiment

[0030] The preferred specific embodiments of the present invention will be described below with reference to the accompanying drawings:

[0031] Such as figure 1 The shown integrated natural circulation baffle reactor is mainly composed of a chemical water mixing device 1, a reaction tank 2 and an aeration device 3. The structure and functions of the components will be further explained below:

[0032] The medicine water mixing device 1 mainly includes a tubular mixer 11, a wastewater inlet pipe 12 and a hydrogen peroxide dosing pipe 13 respectively connected to the front end of the tubular mixer 11, and a water distributor connected to the rear end of the tubular mixer 11 14. A valve 131 is also provided on the hydrogen peroxide dosing pipe 13, and the amount of hydrogen peroxide added is controlled by adjusting the valve 131. After the waste water and the hydrogen peroxide enter into the tubular mixer 11, they are quickly and uniformly mixed in the tubular mixer 11, and the ...

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...
