Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0030] refer to Figure 1-6 , a thermal recycling industrial sewage treatment process, the steps are as follows;

[0031] S1: First, the sewage is pretreated. The pretreatment is carried out by the heat collection box. The sewage enters the device and is fully heated by the heat absorbed by the heat absorbing plate on the outer periphery of the device. After the pretreatment is completed;

[0032] S2: Filter the sewage. When the pretreated sewage flows through the filter, the large impurities in the sewage are filtered out by the filter, so that the sewage flows down through the filter. After the filtration is completed;

[0033] S3: The heat of the sewage is used f...

Abstract

The invention discloses a heat cyclic utilization industrial sewage treatment process. The heat cyclic utilization industrial sewage treatment process comprises the following steps; firstly, sewage is pretreated by a heat collection box, and the sewage enters the device and is fully heated by heat absorbed by a heat absorption plate on the periphery of the device; the sewage is filtered, when the pretreated sewage flows through a filter screen, large impurities in the sewage are filtered out by the filter screen, so that the sewage flows down through the filter screen, and after filtering is completed, a liquid outlet pull rope is pulled through sliding of a sliding plate, so that the liquid outlet pull rope pulls a sealing plate to slide inwards, the sealing plate and a limiting block cannot form a sealing structure, then the liquid tank is opened, treatment liquid in the liquid tank is discharged due to continuous adding of the treatment liquid through a liquid inlet pipe, sufficient adding of the treatment liquid is achieved, the quality and efficiency of sewage treatment are ensured, the efficiency of sewage treatment is improved, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of industrial sewage treatment, in particular to a thermal recycling industrial sewage treatment process. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for 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. [0003] The traditional sewage treatment process basically treats the pollutants in the sewage, and cannot collect and utilize the heat in the sewage, which will cause a waste of resources, increase the cost of sewage treatment, and bring A certain economic burden, so we propose a thermal recycling industrial sewage treatment process to solve the above problems. ...
