Domestic sewage solid greasy dirt condensation and separation device

Abstract

The invention discloses a domestic sewage solid greasy dirt coagulation and separation device, and belongs to the technical field of sewage treatment. A plurality of greasy dirt separation balls are put into a sewage storage bin, greasy dirt on the surface of sewage enters an upper oil absorption hemisphere through a through hole, an adsorption pushing ball adsorbs greasy dirt to expand, and a pushing top block separates a pair of connecting magnetic blocks; meanwhile, under the elastic action of a compression spring, a pair of connecting magnetic blocks are far away from each other and are limited at the same time, so that a pair of butt joint plates are far away from each other, adjacent rectangular magnetic blocks are connected with each other, and water and oil stains are effectively separated; then barium hydroxide solution in the reaction bin is in contact with an ammonium chloride solution in the inner cavity to generate an endothermic reaction, and meanwhile, under the elasticaction of the elastic telescopic block and the pushing spring, the plugging block makes contact with the upper inner wall of the butt-joint plate, and the rising column stretches out of the butt-jointplate and the annular telescopic heat conduction column to transfer temperature, so that oil stains are solidified through heat absorption of the rising column and the annular conical block, and therefore the oil stains on the sewage surface are effectively solidified and separated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solid oil pollution coagulation and separation device for domestic sewage. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.). The organic matter present in domestic sewage is extremely unstable and easily rots to produce stench. Bacteria and pathogens reproduce in large numbers using organic matter in domestic sewage as nutrients, which can lead to the spread of infectious diseases. Therefore, domestic sewa...

Problems solved by technology

Due to the high water content, it cannot meet the calorific value requirements of waste incineration, and it is not suitable for direct landfill. At the same time, a large amount of kitchen sewage enters the secondary market, which poses a great potential threat to human health. Therefore, it is necessary to effectively treat the oil in domestic sewage. separate, recycle
