Skid-mounted device of oil-containing sewage

Abstract

The invention discloses a skid-mounted device of oil-containing sewage. The skid-mounted device comprises an installation substrate, an oil-water separator, a dissolved air flotation system, a medicine adding system and a filtering system and is characterized in that the left lower corner of the installation substrate is provided with the medicine adding system, the right lower corner of the installation substrate is provided with the filtering system, an operating floor is arranged between the filtering system and the medicine adding system; the left side of the operating floor is provided with an electric cabinet; a crawling ladder welded with the operating floor is arranged below the electric cabinet; an oil-water separator is arranged above the medicine adding device; a water tank is arranged above the filtering system; the dissolved air flotation system is arranged between the oil-water separator and the water tank. Since the technical scheme is adopted, the skid-mounted device has the beneficial effects that various types of sewage can be processed, and a processing effect of oil-containing complex sewage is very thorough, the effect is good, and a success rate is high, and problems and weaknesses in the technical field can be greatly solved so as to facilitate the healthy and ordered development of the industry.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a skid-mounted device for oily sewage. Background technique [0002] Harm of oily sewage to enterprises. The wastewater containing emulsified oil will settle together with the suspended particles and iron oxide scale in the wastewater in the process facilities and pipeline equipment, forming a viscous sludge mass, which will block the pipeline and equipment and affect the normal production. Environmental hazards of oily sewage. The impact of oily substances on the environment is multi-faceted, such as polluting the water body, forming an oil film on the water surface, which can hinder the re-oxygenation of the water body. Due to the reduction of dissolved oxygen in the water body, the photosynthesis of algae is limited, which affects the normal growth of aquatic organisms. Aquatic animals and plants have oily smell or toxicity, and even make the water stink and destroy the utilizati...

AI Technical Summary

Problems solved by technology

The impact of oil substances on the environment is multifaceted, such as polluting the water body, forming an oil film on the water surface, which can hinder the reoxygenation of the water body, and due to the reduction of dissolved oxygen in the water body, the photosynthesis of algae is limited, affecting the normal growth of aquatic organisms, making Aquatic plants and animals have oily smell or toxicity, and even make the water body smelly, destroying the utilization value of water resources; the oil adheres to the gills of the fish, which can suffocate the fish. When the concentration is 200mg / L, the fish cannot survive; it adheres to the algae , plankton, can kill them; oil will inhibit waterfowl spawning and hatching, and in severe cases, a large number of birds will die; if oily wastewater is used to irrigate farmland, oil and its derivatives will cover the surface of soil and plants, blocking the soil Pores prevent air from penetrating, prevent soil and microorganisms from performing normal metabolism, reduce the quality and practical value of agricultural products, and cause crop yield reduction or death in severe cases, oil migrates downward in the soil, and may cause serious groundwater pollution

[0003] At present, chemical method, air flotation method, filter adsorption method and other processes are mostly used in the treatment of oily sewage. Most of the above-mentioned processes are used in the treatment, and the sewage source is single, and the treatment is not thorough. For complex oily sewage after treatment The result is very unsatisfactory. Affected by complex factors of oil pollution, the density of oil pollution varies, and failure of treatment results often occurs.
