Description

The invention relates to the field of treatment of industrial and storm wastewater containing non-ferrous and rare metal ions, suspended particles, oil products, oils and fats, and can be used in non-ferrous metallurgy, in particular when treating industrial and storm wastewater of titanium-magnesium production.
Known apparatuses and installations for treating industrial and storm sewage of the chemical industry (see the book. Wastewater treatment in the chemical industry. - Proskuryakov VA, Shmidt LI - L .: Chemistry, 1977, pp. 377-391 ), including sedimentation tanks and oil traps for the mechanical treatment of wastewater from coarse particles and oil products, flotation plants, filters, apparatus using various types of coagulants and flocculants, adsorbers using active carbon as adsorbents, biological treatment in aeration tanks.
The disadvantage of such plants and apparatus for treating industrial and storm sewage is their low degree of purification, so the wastewater treatment of oil products reaches a residual content of 50-150 mg / l, and the degree of capture of mechanical impurities is 50%. In addition, the proposed apparatus for treating industrial and storm wastewater of various chemical industries do not provide a specific installation for treating industrial and storm wastewater of titanium-magnesium production, in particular, treating wastewater from non-ferrous and rare metal ions.
Known installation for wastewater treatment from petroleum products (RF patent No. 2235692, publ. 09/10/2004). The installation contains sewer pipelines, manholes, an oil trap equipped with hydraulic locks with a vertical pipe, smoothly turning into an ejector cone. In addition, manholes contain immobilized strains of microorganisms. Contaminated wastewater enters the oil trap, then into the mud trap of mechanical impurities, then through the pipeline enter the bioreactor well, into which immobilized strains of microorganisms are introduced to process impurities of a fecal nature. Treated wastewater enters the city sewer.
A disadvantage of the known installation for the treatment of industrial and storm sewage is its low degree of purification, since they purify only mechanical impurities in the oil trap and biological treatment with strains of microorganisms. In addition, the claimed installation is not intended for the treatment of industrial and storm sewage from non-ferrous and rare metal ions present in wastewater at non-ferrous metallurgy enterprises.
A known installation for cleaning storm water from oil products and suspended particles (PM RF No. 115776, publ. 05/10/2012), consisting of a tank divided by partitions with overflow openings into several chambers: a receiving chamber, a settling tank, a stilling chamber and a filter chamber with sorption filler . The tank also contains manholes with hatches, an inlet manifold and an outlet pipe. To reduce the speed of storm drains, the intake manifold of the receiving chamber is made with a conical nozzle. A removable mesh basket with a blind base in the form of a trapezoidal section hopper is installed in the intake chamber on the inlet manifold, the front wall of the basket in contact with the conical nozzle and made of a grating with a larger gap than other walls. In the sump installed inclined coalescent plates. The filtration chamber consists of two sections separated by a perforated partition; removable baskets with vertical flat cartridges filled with an adsorber are installed in the sections. In addition, manholes with hatches of the receiving chamber and the sump are equipped with submersible centrifugal pumps to remove floating oil products, and at the bottom of the installation, a perforated pipe is installed along its axis for washing the chambers.
The disadvantage of the installation for the treatment of storm sewage is the complexity of the hardware design. This leads to high costs for the manufacture of the installation and its maintenance. In addition, the described installation is not intended for the treatment of industrial and storm sewage from non-ferrous and rare metal ions present in the wastewater of titanium-magnesium production.
Known installation for the treatment of industrial and storm sewage non-ferrous metallurgy, as well as apparatus and installations for their treatment (Prince. Cleaning and control of wastewater from non-ferrous metallurgy enterprises. - Baymakhanov MT, Lebedev KB, Antonov VN , Ozerov A.I. - M.: Metallurgy, 1983, pp. 14-48, 74-98, 127-134, 182-188), by the number of common features adopted for the closest analogue prototype. Titanium-magnesium production is based on large water consumption, as a result, a significant amount of industrial and storm sewage is generated, for the treatment of which various treatment options are proposed using various types of separate apparatus and equipment. To do this, industrial and storm sewage is collected in a prefabricated collector and fed to the oil trap for purification by sedimentation to remove oil-tar-oil-containing impurities and suspended solids from the surface of the sewage, either in the ultraviolet disinfection chamber or in a filter chamber with sorption filler, at the same time, wastewater consumption is recorded using a wide range of flow meters. The treated effluents are collected in a prefabricated collector and from it are fed into the recycled water supply network for reuse of treated wastewater.
The disadvantage of the above installation for the treatment of industrial and storm sewage from non-ferrous metallurgy is the low degree of wastewater treatment from pollution. Wastewater of titanium-magnesium production is largely contaminated with oil products (spent emulsions), cyanides, acids, salts, heavy metal ions and other impurities. Due to the tightening of environmental authorities, discharges into wastewater bodies without prior treatment to standards are prohibited. The low degree of wastewater treatment does not allow to discharge effluents into water bodies. In addition, with a low degree of purification, when using contaminated wastewater for use in recycled water supply, the service life of equipment in which recycled water is used to cool the titanium-magnesium production apparatus is reduced.
The technical result is aimed at eliminating the disadvantages of the prototype and can reduce the negative impact on the environment of harmful impurities by increasing the degree of purification of industrial and wastewater of titanium-magnesium production, improve the quality of wastewater used as recycled water for cooling titanium production apparatuses, washing equipment and instruments in manufacturing process for producing titanium and magnesium.
The objective of the technical solution is to increase the degree of purification of industrial and storm sewage from harmful impurities of non-ferrous and rare metals, as well as from petroleum products and suspended solids, to increase the life of apparatus and equipment using wastewater as recycled water.
The technical result is achieved by the fact that the proposed installation for the treatment of industrial and storm sewage of titanium-magnesium production, containing a prefabricated collector, an oil trap, a disinfection chamber with ultraviolet irradiation, a filter chamber with sorption filler, a wastewater flow metering chamber, a collector and a reverse water supply network, in which new is that the cameras are arranged in the following sequence: the oil trap is connected to the ultraviolet disinfection chamber by irradiation with a pipeline passing through the disinfection chamber and equipped with an ultraviolet irradiation device with a wavelength of 250-270 nm, the disinfection chamber is connected to the wastewater flow measuring chamber by a pipe passing through the flow measuring chamber and equipped with an acoustic flow meter, the flow measuring chamber is connected by a pipeline to the filtration chamber with sorption filler, the filtration chamber is connected by a pipeline to a collection collector for treated wastewater, in addition, the installation with abzhena pumping station for pumping the effluent, which conduit is connected on one side with the collecting manifold for the effluent, and on the other - with a circulating water supply network. In addition, the rate of transmission of wastewater through the pipeline through the ultraviolet disinfection chamber, the wastewater flow measuring chamber and the filter chamber with sorption filler is not more than 24 m 3 / h.
In addition, a carbon sorbent of the MIU-C2 type is used as a sorption filler in the filtration chamber.
The installation for the treatment of industrial and storm sewage of titanium-magnesium production in the form of chambers interconnected by pipelines in a certain sequence: from a prefabricated collector to an oil trap, from an oil trap to a disinfection chamber, from a disinfection chamber to a flow measurement chamber, from a flow measurement chamber to a filtration chamber with sorption filler and from the filtration chamber to the prefabricated sewage collector, it allows to achieve the highest degree of wastewater treatment from oil heat products, suspended solids, from non-ferrous and rare metal impurities, reduce the environmental impact of harmful impurities contained in industrial and storm sewage of titanium-magnesium production, improve the quality of recycled water used in cooling apparatus and equipment of titanium-magnesium production.
Placing the pipeline through which wastewater is transferred in the disinfection chamber and installing an ultraviolet irradiation device with a wavelength of 250-270 nm on the pipeline allows the most complete disinfection of storm sewage and thereby allows to achieve the greatest degree of wastewater treatment, reduce environmental impact harmful impurities, improve the quality of recycled water used in the cooling of apparatus and equipment of titanium-magnesium production.
Placing the pipeline with wastewater in the wastewater flow measuring chamber and installing an acoustic flow meter on the pipeline with wastewater allows wastewater to be measured and taken into account in the filter chamber with sorption filler, which makes it possible to evenly use the sorption filler in the filter chamber, and to evenly feed sewage into the water recycling network. This allows to achieve the greatest degree of wastewater treatment from oil products, suspended solids, from non-ferrous and rare metal impurities, to reduce the environmental impact of harmful impurities contained in industrial and storm sewage of titanium-magnesium production, to improve the quality of recycled water used in the cooling of apparatus and equipment titanium-magnesium production.
Providing a pumping station with a pumping station and connecting the pumping station with a pipe on one side with a collection collector for treated wastewater and on the other with a recycled water supply network allows to accelerate the supply of wastewater to the recycled water supply network, and to increase the water flow rate in the recycled water supply network. This allows you to reduce the discharge of wastewater into water bodies and thereby reduce their pollution with harmful impurities.

Figure 1 shows a plant for the treatment of industrial and storm sewage of titanium-magnesium production, consisting of a prefabricated collector 1, oil trap 2, connected by a pipe 3 to a UV disinfection chamber 4 with an ultraviolet irradiation device 5, with a wastewater flow measuring chamber 6 with an acoustic flowmeter 7, a filtration chamber 8 with sorption filler 9, a collection collector 10 for collecting treated wastewater, a pumping station 11, a water recycling network 12.
The industrial applicability is confirmed by the following example of the installation for the treatment of industrial and storm sewage of titanium-magnesium production.
The main sources of pollution of industrial and storm sewage in titanium-magnesium production are industrial transport, water flushes during cleaning of work sites (oil smudges in stuffing box packing of gearboxes, pumps, fans, transformers and other technological equipment), waste water after cooling of hot workshop equipment. Industrial wastewater enters the industrial sewer after using it as recycled water when cooling the separation apparatus upon receipt of titanium, and washing equipment from contamination. In addition, petroleum products enter the washing wastewater when snow melts, during rain flows through the territory of the site for the production of titanium and magnesium. Petroleum products are in solutions in emulsified dissolved form, as well as in the form of a film layer floating on the surface. The amount of dissolved petroleum products in industrial and storm sewage is a significant amount, and the cleaning of petroleum products must be carried out by using a process unit that includes several stages of treatment. At the first stage, floating oil products are separated from the surface of the effluents by mechanical cleaning, then a deeper cleaning of oil products in a dissolved, colloidal state is carried out using natural mineral sorbents. Industrial and storm sewage of titanium-magnesium production by gravity flows into a prefabricated collector 1, from where it flows by gravity to an oil trap 2. Wastewater composition to an oil trap 2: oil products - from 3.3 to 866 mg / dm 3 , suspended solids - from 5.0- 27 mg / dm 3 . The amount of oil products and suspended solids depends on weather conditions associated with the period of active snowmelt. The oil trap 2 with a size of 2000 × 4200 mm and a height of 3200 mm is a monolithic reinforced concrete tank that provides separation and capture of oil and oil products and mechanical treatment of industrial and storm sewage by the settling method. Inside the oil trap 2, a concrete partition with a height of 3000 mm is made. Wastewater enters the oil trap 2 through the inlet pipe and is poured out of the oil trap through the outlet pipe. The wastewater flow rate in the oil trap 2 is 1.6–13 l / s. In the floor slabs of the oil trap 2, there are three inspection manholes with ceramic brick necks closed by cast-iron hatches. In the manufacture of reinforced concrete structures for the walls of the oil trap 2, concrete B15 was used, reinforced with steel mesh of class AIII, embedded products from reinforcement class AI according to GOST 5781-82. Welding of reinforcing bars should be carried out by spot welding according to GOST 14098-91. Periodically, the upper layer of wastewater in the oil trap 2 is pumped through an inspection hole into the tank of the KO-512 sludge settler. Oil-containing wastewater is taken out for processing to a specialized organization that has an appropriate license. Sludge from oil trap 2 is loaded into a sealed container and disposed of at a landfill of production and consumption waste. Wastewater after the oil trap 2 contains oil products from 0.14-3.1 mg / dm 3 (VAT norms are 0.05 mg / dm 3 ), suspended particles from 3 to 9 mg / dm 3 (VAT norms are 7.55 mg / dm 3 ), which does not allow the discharge of waste water into water bodies. Next, the wastewater from the oil trap 2 through a pipe 3 enters the ultraviolet disinfection chamber 4, which is made in the form of a container, through whose walls passes a sewage pipe 3, on which a UVOV-15 type ultraviolet irradiation device 5 with a wavelength of 250-270 is installed nm and the transmission rate of wastewater through the camera 4 ultraviolet irradiation 24 m 3 / h Disinfection is performed with an average dose of water irradiation of at least 30 mJ / cm 2 . The camera capacity is 65 m 3 / h. The number of lamps is 5 pieces, power consumption is 1.8 kW. From the disinfection chamber 4 through the pipeline 3, the wastewater is supplied to the wastewater flow measuring chamber 6. The chamber 6 for measuring the flow of wastewater is made in the form of a rectangular monolithic reinforced concrete tank with a size of 3500 × 2500 mm and a depth of 2500 mm. The wastewater flow rate is measured using an acoustic flowmeter 7 with an integrator ECHO-R-02, which is installed on a pipeline 3 installed in the chamber 6. The wastewater flow measurement chamber 6 is connected by a pipeline 3 to a filtration chamber 8 with sorption filler 9. A filtration chamber 8 sorption with filler 9 is formed as a container size of 7350 × 5650 mm and comprises a free-flow filter type FSB-2 capacity of 24 m 3 / h in complete submersible pump for washing sorption filler 9. as sorption This filler 9 uses a carbon sorbent type MIU-C2 (Miusorb), which is most effective for wastewater treatment from oil products, and also provides wastewater treatment from dissolved iron, copper, zinc, lead, titanium, chromium, nickel, cadmium, ammonium to NDC. The structure of the filler of sorbent type 9 MIU-C2 is associated with many carboxyl, hydroxyl and phenolic groups, the hydrogen atom of which is replaced by cations present in the treated effluents. Prefabricated collectors 1 and 10 are made of a circular shape with a diameter of 1000-2000 mm, made of precast concrete, with necks of ceramic brick and lockable cast-iron hatches. Pumping station 11, using pipelines 3, connects the collecting manifold 10 and the water recycling network 12 and includes two submersible pumps 11 (one standby) of type SLV.65.65.40 / 2/510 with a capacity of 24 m 3 / h and a head height of 20 m. Installation for purification of industrial and storm sewage of titanium-magnesium production consists of successively arranged chambers, mutually connected to each other by pipeline 3, and includes: a prefabricated collector 1 for collecting wastewater - an oil trap 2 - a UV disinfection chamber 4 - a camera 6 eniya wastewater flow - the filtration chamber 8 filled with sorption 9 - collector 10 for collecting effluent - the pumping station 11 - chain 12 circulating water. Thus, the proposed installation for the treatment of industrial and storm sewage of titanium-magnesium production allows to increase the degree of sewage treatment to the following content:
petroleum products - 88.5-99.0%,
ammonia - 89, -92% (there are no excess VAT),
iron - up to 90% (no excess VAT),
titanium - up to 99% (no excess VAT),
chrome - up to 54.5% (there are no excess VAT),
Manganese 43.8% (no excess VAT),
magnesium - up to 2.6% (there are no excess VAT),
suspended solids - 99%.
