Definitions
- the invention relates to techniques for the disinfection of sludges from domestic and industrial wastewater used as the basis for organic fertilizers for agriculture.
- a known method of disinfecting sewage sludge which includes preliminary dewatering of sludge, granulation and heat treatment.
- the heat treatment is carried out in a fluidized bed in two stages when using flue gases supplied with a temperature of 200-400 ° C as a coolant, while at the first stage the temperature in the layer is maintained at 60-80 ° C at a flue gas supply speed of 5-12 m / s , and in the second stage, the temperature is maintained at 120-140 ° C, after which the granules are cooled, and spent waste gases are used to control and maintain the temperature in the layer [RF Patent N ° 2075198 C02F 1/50].
- a known method of disinfecting sewage sludge from pathogens of parasitic diseases by aerobic stabilization In an aerobic stabilizer with a sediment humidity of 94-95%, a solution of an ovicidal preparation made from crushed dry potato seedlings is added at a rate of consumption of a dry preparation of 0.001- OD g / m 3 of sediment and the time of joint exposure to helminth eggs of aerobic stabilization and the preparation for at least 8 hours.
- RF patent N ° 212042 C02F 1 1/00 [RF patent N ° 212042 C02F 1 1/00].
- the disadvantage of this method is the use of thiazone or ammonia water as a disinfecting reagent, which increases the cost of operations and makes recycling products environmentally unsafe.
- Disinfecting waste is crushed, mixed, loaded into the chamber and created in it a sealed volume between the piston and the valve, through which serves air under pressure of 0.4-1.0 MPa for 1-5 minutes, and then create a vacuum of 0.01-0.03 MPa for 1-6 minutes.
- the disadvantage of this method is the length of the disinfection process.
- the method also makes increased demands on equipment and an automatic control system, which is associated with the use of pressure and the need to create alternating pressure and vacuum in the chamber.
- the disinfection process is delayed due to the fact that before starting evacuation, it is first necessary to "bleed” the air under pressure.
- the objective of the present invention is to accelerate the disinfection of sludge from domestic and industrial wastewater and simplify the method in connection with the use of equipment with reduced strength and lower metal consumption.
- the problem is achieved in that in the method of disinfecting wastewater sludge by acting on rarefaction sludge, the vacuum is produced by high-speed vacuum-pulse effects using a receiver, high-speed valves and pipelines with a pulse duration of not more than 1, 0 sec. and residual pressure in the vacuum system of not more than 20 mm RT. Art., to achieve the necessary degree of disinfection.
- sewage sludge is subjected to a high-speed vacuum-pulse exposure in the disinfection chamber, resulting in a sharp decompression of pathogenic bacteria, leading to their destruction and death.
- This allows you to create, in comparison with the prototype, a reduced time disinfection process.
- the exclusion of excessive (increased) pressure in the disinfection chamber makes it possible to use equipment with reduced strength and lower metal consumption. It also eliminates the need to "bleed" the air under pressure.
- the proposed method for disinfecting sewage sludge is as follows.
- Sewage sludge is placed in a disinfection chamber, connected by pipelines to high-speed valves with a receiver, and high-speed vacuum-pulse effects with a pulse duration of not more than 1.0 sec are produced. with a residual pressure in the disinfection chamber of not more than 20 mm RT.
- the inventive method is confirmed by experimental data.
- the proposed method allows you to speed up the process, is economical in time, reliable in the quality of disinfection of sewage sludge, eliminates the need for additional equipment, easy to operate.
