Treatment agent for oily wastewater and preparation method of treatment agent

Abstract

The invention discloses a treatment agent for oily wastewater and a preparation method of the treatment agent. the treatment agent comprises the following raw materials in parts by weight: 6-12 partsof bentonite, 5-10 parts of vermiculite powder, 4-6 parts of polyvinyl alcohol, 1.3-2.8 parts of formamide, 3-6 parts of gelatin, 15-22 parts of viola tricolor, 6-8 parts of nanographene, 3-5 parts ofmagnetite slag, 2.4-4 parts of fruit tannin and 3.5-5 parts of tartaric acid. The treatment agent provided by the invention is wide in source of raw materials, less in dosage by adopting different preparation processes for various raw materials and then carrying out a reaction of the various raw materials in a reaction kettle, good in adsorption, flocculation and sedimentation effect on oil, highin oil removal rate, and capable of meeting use requirements of people.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a treatment agent for oily wastewater. Background technique [0002] With the rapid development of the economy, the protection and rational use of water resources has become an important issue that people generally pay attention to, and urban sewage treatment occupies a pivotal position in urban modernization. Water pollution and water shortage are one of the serious environmental problems facing our country. According to statistics, since 1985, my country's annual sewage discharge has been maintained at around 35 billion to 40 billion m3. my country's urban sewage treatment rate was only 3.3% in 1991, and a large amount of sewage was directly discharged, causing 82% of the country's 532 rivers to be polluted to varying degrees. The direct discharge of a large amount of sewage not only destroys ecology and aggravates water shortages, but also seriously endangers industrial a...

Problems solved by technology

The impact of oil substances on the environment is various, such as polluting the water body, forming an oil film on the water surface, hindering the reoxygenation of the water body, and the reduction of dissolved oxygen in the water body, the photosynthesis of algae is limited, affecting its normal growth and even death, making the water body It will become smelly and destroy the utilization value of water resources; oil will inhibit the spawning and hatching of water birds, and in severe cases will have a major impact on the survival of water birds; oil can adhere to fish gills, suffocate fish, and adhere to algae and plankton If the oily waste water is used to irrigate the farmland, the oil and its derivatives will cover the surface of the soil and plants, block the pores of the soil, prevent the infiltration of air, prevent the normal metabolism of the soil and microorganisms, and cause crop yield reduction in severe cases or die, the oil migrates downward in the soil, and may also cause serious groundwater pollution

[0004] Oil-absorbing materials are currently important materials used to treat oily wastewater, including activated carbon, clay, natural fiber fabrics, polypropylene fibers, etc., but the existing oil-absorbing materials cannot meet the waste oil recovery and oil pollution in terms of oil absorption performance and production capacity. Environmental governance requirements, which brings inconvenience to people's sewage treatment
