Problems solved by technology

[0007] The existing deficiencies of the existing biochemical sewage treatment devices are: the low-temperature environment of the biochemical method has poor treatment capacity:
[0008] In the north, especially in the three northeastern provinces, Inner Mongolia, Xinjiang and other regions, the temperature in winter is -20 degrees Celsius to -30 degrees Celsius for a long time. Even if the sewage treatment equipment takes insulation measures, it rarely reaches the normal operating temperature. Some sewage treatment plants often adopt Stop operation in winter, restart operation in late April or early May, or aerate as usual in winter, but because the water temperature is too low, microorganisms cannot grow and reproduce, the sludge in the biochemical pool loses activity, and the water quality deteriorates, unable to achieve the required The purpose of water purification

Embodiment 1

[0031] Application of domestic sewage treatment:

[0032] The integrated treatment device for biochemical sewage across temperature difference of the present invention can be set above or below the ground, such as Figure 5 As shown: when it is installed below the ground 40, its top is 1 to 2 meters away from the ground, and the sewage enters the cross-temperature difference biochemical sewage integrated treatment device through the water inlet pipe 1, and the treated clean water is stored in the clear water pool 10, and the clear water pool 10 When the liquid level was at a high liquid level, start the clear water outlet pump 19 to discharge the water in the clear water pool 10.

[0033] When the water temperature is above 15°C, the sewage enters the regulating tank 2 of the integrated biochemical sewage treatment device across temperature difference through the water inlet pipe. The sewage and sludge are mixed to make the water quality uniform and easy for subsequent anaero...

Embodiment 2

[0038] Application of industrial wastewater treatment:

[0039] In the application of industrial wastewater treatment, the integrated biochemical sewage treatment device across the temperature difference of the present invention is a section in the whole process. According to the difference in water quality and the difference in water outlet requirements, the front section of the water inlet needs to pretreat the incoming water. Make the water quality meet the requirements of biochemical treatment. Generally, the COD of industrial wastewater is much higher than that of domestic sewage, and its biodegradability is worse than that of domestic sewage. The quality of its effluent generally cannot meet the reuse or discharge standards. Filtration, reverse osmosis, EDI and other systems.

Abstract

The invention discloses a cross-temperature-difference integrated wastewater treatment device capable of biochemical treatment, belonging to the technical field of environmentally friendly wastewatertreatment. The device adopts a process combining a biochemical method and a chemical oxidation method, the overall operation is stable throughout the year, and the treatment effect is good under low temperature environment. The overall structure of the device is a sealed tank or an opened tank or a pot-type tank. The device includes a conditioning tank, an anaerobic device, a front separation device, a chemical oxidation device, an aerobic tank or a front aerobic tank and a rear aerobic tank, a flocculation device, a rear separation device and a clear water tank. When the environment temperature and the water temperature are suitable for biochemical treatment, the biochemical method is adopted to treat wastewater; when the environment temperature and water temperature are too low, activated sludge or biofilm loses its activity, and the treatment is poor in effect or invalid, the chemical oxidation method or combination of the biochemical method and the chemical oxidation method is adopted to treat the wastewater, thus achieving the treatment effect that discharged water of the disclosed device at low temperature meets environment friendly emission or reuse standards.

Description

technical field [0001] The invention relates to an integrated sewage treatment device, which belongs to the technical field of environmental protection sewage treatment, in particular to an integrated biochemical sewage treatment device adapted to temperature changes across temperature differences. Background technique [0002] Biochemical sewage treatment technology is a common treatment method for biochemical domestic sewage and industrial wastewater, mainly including biofilm method and activated sludge method, through the proliferation and metabolism of microorganisms in activated sludge and biofilm to remove pollution in water bodies substances to purify the water body. [0003] The overall structure of the biochemical sewage integrated treatment device is divided into a closed box body or an open box body or a tank type tank body. [0004] Closed box integrated processing device, its upper part is the top plate fixedly connected with the side wall, each inner pool body...
