Condensation type sewage impurity treatment process

Abstract

The invention discloses a condensation type sewage impurity treatment process and belongs to the technical field of sewage impurity treatment. The condensation type sewage impurity treatment process includes the steps of heat storage and pretreatment of sewage, mixing and blending of sewage liquid, grading filtration of mixed liquid, dehydration of the mixed liquid, accumulation of sewage impurities in dissolution layer and discharge of the impurities by wind pressure; grading and filtration treatment of domestic sewage discharged from residential areas can be realized, meanwhile, the impurities in the domestic sewage can be condensed into solid particles which are blown to the planning area by a blower, and fertilizer of the land in crop planting area is improved; compared with the priorart, the condensation type sewage impurity treatment process has the advantages that domestic sewage treatment process is simplified, treatment time is reduced, and the efficiency in sewage purification is improved; meanwhile, the domestic sewage is reused, the damage of the sewage to the external environment is reduced, and practical guidance for developing new energy in rural areas and promotingsustainable development of rural economy and society is provided.

Description

Technical field [0001] The present invention relates to the technical field of sewage impurity treatment, and more specifically, to a coagulation-type sewage impurity treatment process. Background technique [0002] Sewage usually refers to polluted water discharged from life and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. Such as industrial wastewater, which contains many pollutants and complex components, not only difficult to purify in the water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for most of the pollutants emitted by industry. The pollutants contained in industrial ...

Problems solved by technology

[0008] The existing units that treat domestic sewage generated by residents mostly deal with sewage in a general manner. For example, the composition of domestic sewage is relatively fixed, and the main components contain organic substances such as carbohydrates, proteins, amino acids, fats, etc., which are more suitable for bacteria. growth and become a place for the survival and reproduction of bacteria and viruses, but on the other hand, domestic sewage generally does not contain toxicity, so in order to make this part of sewage treatment to a clean standard, it is necessary to perform multiple filtration and add adsorbents and other treatment methods. It not only causes a waste of chemical reagent resources for sewage treatment, but also takes a long time for sewage treatment
