Abstract

The present invention relates to a method for treating waste water by oxygen-containing water reflux type biological activated carbon and a device therefore the device mainly comprises two units: an activated carbon tank and an oxygen supply tank. The amount of pollutants removed by the biological activated carbon waste water treatment method is related to the supplying amount of oxygen dissolved. Usually 1 mg/L of oxygen dissolved can remove about 1 mg/L of COD. In the present invention, the inlet water is introduced into the oxygen supply tank for aeration, and the aerated oxygen-enriched water in the oxygen supply tank is fed to the bottom of the activated carbon tank, and flows upward to swell the activated carbon layer. When oxygen-containing water flows through the activated carbon layer, microorganisms on the activated carbon particles use the enriched oxygen concentration to promote the decomposition of the pollutants (e.g. COD, BOD, TKN, etc.) adsorbed on the activated carbon; this is an improved biological activated carbon system. A majority of the upper clear liquid in the activated carbon tank is fed to the oxygen supply tank for aeration, while a small amount thereof is discharged. The present invention can make a proper treatment on waste water of different properties by controlling the reflux ratio of oxygen-containing water/inlet water and the oxygen supplied from the oxygen supply tank. The invented method is easy to operate, has a simple device and a small reaction tank, as well as is low in wearing of the activated carbon.

Description of the invention α) Field of industrial utilization The present invention relates to a method and a device for treating wastewater using a group of biological activated carbon units and a group of oxygen supply units, and the treated wastewater is pumped to the oxygen supply unit before being discharged. Oxygen-containing water is returned to the biologically active unit to provide sufficient oxygen to the microorganisms on the activated carbon to remove pollutants such as COD, BOD, and TKN from water / wastewater. Its application scope can include secondary treatment of wastewater, advanced treatment, advanced treatment of carcinogenic precursors such as ammonia nitrogen removal from drinking water, and tri-methane. The invention can also be used in combination with the ozone system for further treatment. In order to achieve the goal of final water purification by the conventional technology, the active carbon adsorption unit is connected to the back end of the traditional biological treatment system to remove residual pollutants such as COD, BOD, TKN, etc. It is widely used by general environmental engineering practitioners, but the activated carbon adsorption unit traditionally used may not perform the function of removing pollutants due to adsorption and saturation. Therefore, it must be discarded to renew or regenerate activated carbon to maintain its original function. The operation manpower and cost are increased, and the waste activated carbon needs to be treated separately, which increases the processing burden. In recent years, a biological activated carbon treatment technology has been developed, that is, an appropriate amount of microorganisms are implanted on the activated carbon so that it not only retains the adsorption capacity of traditional activated carbon, but also exerts the function of biological decomposition and removal. Studies have shown that for the same concentration For organic wastewater, the use of biological carbon can delay the adsorption and saturation of activated carbon by about 5 to 10 times (depending on the type and concentration of wastewater). This proves that biological activated carbon has great application space in advanced treatment of waste (sewage) water. In order to allow microorganisms on activated carbon to effectively decompose the pollutants in the flowing water,

Description of the invention (2) A sufficient amount of oxygen is a necessary condition. At room temperature, the saturated oxygen content in water is about 8 mg / L, that is, if the biological activity of the traditional fixed bed type, the system only allows sewage to flow through the biological activated carbon bed. In the case of oxygen supply, the maximum concentration of coD that can be removed by biological action can only reach 8mg / L. This system has a limited application space except for the application of very low concentration of purified water treatment. If the inflow concentration of a certain wastewater reaches (: 〇1) 200mg / L, it must be repeated, and it must be repeated more than twelve times before the pollution value can be successively degraded to the standard of 80 ti release water of the Republic of China. L is small, which will make the volume aj of the reaction tank a force Z, which is insufficient for actual needs. In order to improve this shortcoming, the more commonly used formula / sleeve is used to maintain the dissolved oxygen content in the biological activated carbon tower tank by continuous aeration, in order to remove the chromatin. In addition, in order to obtain a sufficient amount of dissolved oxygen and agitate (fluidize) the active slave to increase the contact with organic matter and oxygen, it is necessary to provide sufficient kinetic energy for the intake air. The particles are lost due to friction caused by friction, so they need to be replenished frequently, and the concentration of suspended particles (SS) in the release water is relatively high. On the other hand, in this kind of biological organism: tongue-type carbon treatment system, the filling rate of activated carbon cannot be too high] the removal rate of pollutants that guarantees the degree of protection, the total amount of activated carbon on Ϊ, this is bound to As a result, the total volume of the reaction tank is increased, and the reaction tank must be maintained at a certain height or higher to set up a precipitation tank. Otherwise, the fluidized activated carbon will drift. The product of j = increase and height must be increased, which will cause the overall engineering costs to be approved, which is a great disadvantage. In order to overcome the above-mentioned shortcomings encountered in the application of the bioactive charcoal system, the present invention adopts an oxygen-containing water reflux method in a traditional bioactive carbon reaction tank 498056. V. Description of the invention (3) In addition to an "oxygen supply tank" In addition, a reflux device is also provided to provide a large amount of air to the influent waste (sewage) water so that it can enter the biological activated carbon tank to supply sufficient oxygen for the microorganisms to break down the pollutants, and depending on the concentration of the pollutants in the flowing water, The flow ratio of reflux and aeration can be set to ensure the treatment effect. In addition, the present invention drives the flow of activated carbon bed with reflux water. In addition to providing sufficient oxygen for biodegradation, it also avoids the problem of direct supply of oxygen caused by the aerodynamic friction of activated carbon caused by the abrasion. Worrying about the disadvantage of having to build a large or extremely high reaction tank due to the drifting of the broken activated carbon particles, which is more economical. OBJECTS OF THE INVENTION The main purpose of the present invention is to provide a new biological activated carbon technology to improve the shortcomings of the above-mentioned conventional technologies, so that this technology can be more effective and economical than conventional technologies for water / wastewater treatment. . The objectives are: 1. To improve the treatment efficiency: use the oxygen-containing water reflux method to increase the amount of dissolved oxygen in the water to improve the removal efficiency of the pollutants; 2. reduce the wear of activated carbon: use oxygen-containing water reflux to flow from the bottom of the activated carbon bed upward It flows out to the top to make the activated carbon layer slightly swell, reducing friction and abrasion between particles. 3. No pre-treatment facilities are needed: Because the activated carbon bed is in an expanded state, the pores between the particles are not blocked by suspended solids. The water / wastewater treated by the sedimentation tank flows directly without the need to set up a pre-filtration treatment facility. 4. Reduce the height of the unit: Oxygen-containing water is used to supply oxygen and puffed activated carbon layers. It is not a gas riser, so the unit height Can be reduced, 5. Increase the activated carbon filling rate: the activated carbon is not lifted by means of a gas riser, so the filling rate can be increased to
