Embodiment 1

[0095] Example 1: Such as image 3 As shown in the schematic diagram of the non-anaerobic flow of the black and smelly water body, when the treatment station is too close to the residential building, the biogas storage tank 222 has potential safety hazards. The low-temperature and high-concentration sewage in the lower part of the refrigerator 28 exchanges heat with the raw water of the river gushing sewage through the first heat exchanger 24, and becomes normal-temperature high-concentration sewage, which is sent to the aerobic reactor 224 for treatment, and then sent to the sedimentation tank 225. The upper part of the sedimentation tank 225 discharges 0.2 volume of clean water (COD is about 34.5 mg / L, and the removal rate is 85%). The discharged clean water and the normal temperature clean water heated by the condenser 212 are mixed into 1 volume (COD about 11 mg / L) clean water and discharged from the treatment station.

[0096] The COD of the treated effluent is about 11mg / L,...

Embodiment 2

[0097] Example 2: Such as Figure 4 As shown in the schematic diagram of the process of treating black and odorous water in summer conditions, the high-concentration sewage at the lower part of the refrigerator 28 at 0℃ exchanges heat with the raw sewage of the river through the first heat exchanger 24, and becomes 0.2 volume of 23℃ high-concentration sewage (COD About 230mg / L), and then sent to the mud water mixer 218. At the same time, 0.1 volume of 27°C river sludge (COD is about 4000mg / L) is fed into the mud-water mixer 218. The river sludge is first passed through the grit tank 216 and then filtered through the second fine grid 217 to remove larger insoluble Solid matter. The high-concentration sewage and river sludge are mixed in the mud-water mixer 218 to form a 0.3-volume 25°C mud-water mixture (COD is about 1500 mg / L). The mud-water mixture is sent to the auxiliary condenser 219, heated to 36°C by the 40°C refrigerant at the outlet of the heat pump system compressor 2...

Abstract

The invention discloses organic sewage treatment equipment and a method for treating a black and odorous water body by adopting the treatment equipment. The organic sewage treatment equipment comprises a pre-treatment system, a first heat exchanger, a freezing separation system, a biological treatment system and a heat pump system, wherein the pre-treatment system is connected with the first heat exchanger; the first heat exchanger is connected with the freezing separation system through an evaporator of the heat pump system; a low-temperature concentrated sewage outlet of the freezing separation system is connected with the biological treatment system through the first heat exchanger; a low-temperature clean water outlet of the freezing separation system is connected with a clean water outlet of the biological treatment system through a condenser of the heat pump system. According to the equipment and the treatment method thereof, disclosed by the invention, a freezing method and a biological method are ingeniously combined, and the black and odorous water body can be changed into valuable things; the treatment on the black and odorous water body makes profits.

Description

Technical field [0001] The invention belongs to the technical field of water treatment, and specifically relates to an organic sewage treatment equipment and a treatment method thereof. Background technique [0002] The formation of cities is basically built on the river, and most of the city center is on both sides of the river. The rivers flow through the city center and then flow to the main river. However, as the scale of the city continues to expand, the urban population has increased dramatically, and a large amount of domestic sewage and industrial wastewater are discharged into the river without treatment. When the amount of pollutants far exceeds the self-cleaning capacity of the river, black and smelly water bodies are formed. According to the statistics of 2222 monitoring stations in China, 38% of the 138 urban river sections have water quality exceeding Grade V, which has become the worst-hit area in China's water environment pollution. The black and odorous water ...
