Problems solved by technology

[0003] However, the treatment effect of the sewage by the existing methods is not ideal, it is difficult to effectively remove the organic matter in the sewage, and it is easy to cause secondary pollution, and there are many flocs in the sewage. If they are not removed in time, the water body will also be turbid, thus affect water quality

Embodiment 2

[0033] In embodiment 2 of the present invention, a kind of environmental protection type sewage treatment method for textile production comprises the following steps:

[0034] A. Pass the sewage into the filter tube, filter out the large particle impurities and sundries in the sewage through the coarse filter in the filter tube, and then filter out the small particle impurities in the sewage through the fine filter in the filter tube;

[0035] B. Pass the filtered sewage into the adjustment tank, and evenly sprinkle sodium hydroxide into the adjustment tank to adjust the pH value in the sewage to 4;

[0036] C. Pass the sewage in the adjustment tank into the flocculation tank, and configure the following raw materials according to the mass parts: 22 parts of potassium permanganate, 2.7 parts of calcium carbonate, 12 parts of aluminum sulfate and 0.85 parts of polyacrylamide ammonium, mix the above raw materials After uniformity, pour it into the reaction kettle and react for 3...

Abstract

The invention relates to the technical field of sewage treatment, and discloses an environment-friendly sewage treatment method for textile production, which comprises the following steps: A, introducing sewage into a filter pipe, filtering out large-particle impurities and sundries in the sewage through a coarse filter screen in the filter pipe, and filtering out small-particle impurities in the sewage through a fine filter screen in the filter pipe; and B, introducing the filtered sewage into an adjusting tank, uniformly scattering sodium hydroxide into the adjusting tank, and adjusting the pH value of the sewage to 4. According to the method, the sewage treatment effect is ideal, a microbiological degradation mode is adopted, organic matter in sewage is biodegraded, the probability of secondary pollution of water is reduced, flocculates in the sewage can be removed in time, water turbidity is prevented, and therefore the water quality is guaranteed, and the method is high in treatment efficiency and low in input cost, and other pollutants are not generated, so that the method has a certain market popularization prospect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment method for textile production. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields have increasingly entered the daily life of ordinary people. The textile production process will generate more sewage, which needs to be treated before it can be discharged. [0003] However, the treatment effect of the sewage by the existing methods is not ideal, it is difficult to effectively remove the organic matter in the sewage, and it is easy to cause secondary pollution, and there are many flocs in the sewage. If they are not re...
