Embodiment 1

[0027] An embodiment of the present invention provides a sewage treatment process for a sewage plant to decontaminate with a flocculant, comprising the following treatment steps:

[0028] S1. Pass the treated sewage into the interior of the denitrification filter through the sewage pump for preliminary reaction treatment of the sewage;

[0029] S2. Use the sewage pump to transport the sewage treated by the denitrification filter in S1 to the high-density sedimentation tank. At the same time, put the dry flocculant powder into the flocculant preparation machine, and use the water pump to obtain the configuration water and flocculation from the water source. The dry powder of the flocculant is fully mixed to obtain the stock solution of the flocculant;

[0030] S3. Pass the flocculant stock solution obtained in S2 into the interior of the high-density sedimentation tank, and carry out sedimentation treatment on the sewage;

[0031] S4. After the sedimentation treatment, the sew...

Embodiment 2

[0041] An embodiment of the present invention provides a sewage treatment process for a sewage plant to decontaminate with a flocculant, comprising the following treatment steps:

[0042] S1. Pass the treated sewage into the interior of the denitrification filter through the sewage pump for preliminary reaction treatment of the sewage;

[0043] S2. Use the sewage pump to transport the sewage treated by the denitrification filter in S1 to the high-density sedimentation tank. At the same time, put the dry flocculant powder into the flocculant preparation machine, and use the water pump to obtain the configuration water and flocculation from the water source. The dry powder of the flocculant is fully mixed to obtain the stock solution of the flocculant;

[0044] S3. Pass the flocculant stock solution obtained in S2 into the interior of the high-density sedimentation tank, and carry out sedimentation treatment on the sewage;

[0045] S4. After the sedimentation treatment, the sew...

Abstract

The invention provides a sewage treatment process for removing dirt by using a flocculating agent in a sewage plant, and relates to the field of sewage treatment. The sewage treatment process comprises the following treatment steps: S1, introducing treated sewage into a denitrification filter tank through a sewage pump, and carrying out primary reaction treatment on the sewage; S2, conveying the sewage treated by the denitrification filter tank in the step S1 to a high-density sedimentation tank by utilizing the sewage pump while putting flocculant dry powder into a flocculant preparation machine, calling prepared water from a water source by utilizing a water pump, and fully mixing the prepared water with the flocculant dry powder so as to obtain a flocculant stock solution. According tothe sewage treatment process, the flocculating agent is prepared, so that when the sewage treatment process is used for sewage treatment, efficient precipitation can be completed by using a small amount of the flocculating agent so as to reduce the requirements on secondary pollution to the environment and the cost, and the requirements in use can be met.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment process for sewage plants using flocculant decontamination. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. According to the classification of sewage sources, sewage treatment is generally Divided into production sewage treatment and domestic sewage treatment. Production wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater. [0003] For now, the use of flocculants is often involved in sewage treatment. The use of flocculant...
