Life sewage treatment equipment is used to deal with domestic sewage, mainly for rural areas, scenic spots, lodging, inns, service areas and other similar water quality decentralized point source sewage treatment project, the sewage treatment of the various districts centralized into a set of equipment, can significantly shorten the project construction cycle, reduce the cost of civil construction.
General small-scale domestic sewage treatment equipment is divided into prefabricated small-scale domestic sewage treatment equipment and integrated small-scale domestic sewage treatment equipment of two kinds, by the sewage conditioning area, solid and debris separation area, oil and water separation area, sewage biological treatment area, clean water area, residual sludge storage area or chemical treatment area, such as a single or multiple areas, its capacity is not very large, usually less than 500m_/day, and the specific treatment capacity depends on the use of the sewage treatment equipment. The specific treatment capacity depends on the amount of sewage treatment required in the field of use.
Two, what are the characteristics of small domestic sewage treatment equipment
Small domestic sewage treatment equipment is mainly to deal with wastewater discharged from daily life, the main treatment method is the use of biochemical treatment technology of contact oxidation, with the following characteristics:
1, the equipment consists of stainless steel parts of the factory carbon steel anticorrosion treatment or on-site splicing, lightweight, easy transportation, easy installation, corrosion resistance, long service life. Convenient installation, corrosion resistance and long service life.
2, reasonable and compact structural design, buried in the ground is conducive to heat preservation, in the cold winter (-30 ℃) can still operate normally, suitable for China's northern and southern vast climate environment.
3, no pollution, no noise, no odor, reduce secondary pollution, part of the small domestic sewage treatment equipment can even be placed in the pond, and the integration of the surrounding environment, reducing the footprint.
4, small domestic sewage treatment equipment, although the treatment capacity is limited, but it has the flexibility to be used individually or in combination, not subject to the limitations of the amount of sewage, if the amount of water is large, can also be grouped into a centralized treatment, the construction of a small sewage treatment plant (station).
5, the equipment has a high degree of automation, low energy consumption, low management costs.
6, sewage treatment effect is good, domestic sewage grease, garbage and so on more, small sewage treatment equipment can be processed and discharge standards.
Three, living sewage treatment equipment to deal with what sewage
Living sewage treatment equipment, as the name suggests, dealing with, of course, is the living sewage, then what is living sewage?
In fact, domestic sewage is the water used in people's daily life, including water discharged from toilets, bathrooms, kitchens, canteens, laundries, etc. It mainly comes from homes, public *** places, institutions, schools, hospitals, stores, entertainment venues and factories in the inter-life part. Domestic sewage contains more organic matter, such as proteins, animal and plant fats, carbohydrates, urea and ammonia nitrogen and other things, but also contains soaps and detergents, etc., as well as pathogenic microorganisms often found in feces, such as parasitic eggs and intestinal infectious bacteria, etc., this type of sewage needs to be treated in order to become a renewable water resource.
