Embodiment Construction

[0018] Describe in detail below in conjunction with accompanying drawing. It should be noted that the left, right, up, down, etc. mentioned in the following descriptions are all based on the directions shown in the drawings.

[0019] see figure 1 . The bypass purification method of heavily polluted river provided by the present invention, its main structure comprises:

[0020] The secondary effluent of A / O sewage treatment plant (1) is discharged into the river through the submersible pump (3a), and is evenly mixed with the heavily polluted river water through the water diversion stirring device (4); Nitrifying microorganisms inhibit the growth of sulfur bacteria;

[0021] Build an artificial wetland (6) along the river channel to the downstream 10 meter embankment, where the polluted water in the river channel is introduced into the artificial wetland (6) by the submersible pump (3b) and purified, and then discharged by the submersible pump (3c); (COD less than 20mg / L), t...

Abstract

The invention discloses a bypass purification method for heavy polluted rivers. The bypass purification method mainly comprises the following steps: connecting a diversion stirring device of an A / O sewage treatment plant with a heavy polluted river channel, constructing a constructed wetland 10 meters away at the downstream of the river channel along the bank, and introducing a polluted water body inside the river channel into the constructed wetland by using a submersible pump. The invention further discloses a method of the bypass purification method for heavy polluted rivers. The bypass purification method is particularly remarkable in treatment effect on situations such as high content of organisms and nutrient salts and black and odorous water.

Description

technical field [0001] The invention relates to a bypass purification method for heavily polluted rivers. [0002] The invention also relates to a method for treating heavily polluted rivers by using the above-mentioned device. Background technique [0003] At present, most urban rivers in our country have evolved into black and smelly rivers. In many cities in my country, river pollution is widespread and increasingly prominent. Urban sewage is directly discharged into the river, and the river section flowing through the town is seriously polluted. question. [0004] The so-called black odor is due to the water contains a large amount of hydrogen sulfide (H 2 S), the black and odorous state is an extreme state of the water body, and its own characteristics are also very different from other states. The water body has peculiar smell, which is no longer suitable for the survival of aquatic organisms, and the aquatic vegetation is degraded or even extinct. Phytoplankton, zoo...
