Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a multi-carbon source dosing sewage treatment device. Background Art

[0002] During sewage treatment, there is an oxidation nitrification stage. Under the action of denitrifying bacteria, nitrate nitrogen in the sewage is reduced to gaseous nitrogen. The denitrification reaction is a biochemical reaction completed by heterotrophic microorganisms. Under the condition of extremely low dissolved oxygen concentration, they use the oxygen in nitrate as the electron acceptor and organic matter as the electron donor. Since the amount of organic matter in the sewage, that is, the carbon source, is unstable, the ammonia nitrogen in the water source fluctuates greatly after the reaction, and the sewage treatment effect is not good. Therefore, carbon dosing operation is required. The multi-carbon source is a microecological regulator composed of carbon sources with different molecular weights and structures, supplemented with prebiotics and growth-promoting factors.

[0003] However, there is a problem at present, that is, the amount of carbon source discharged by the automatic dosing device each time is uncontrollable, that is, it cannot be quantitatively discharged according to the data fed back by the water quality detection device. Too much or too little carbon source discharge is not good. Too much discharge is likely to cause redundant chemical agent costs and increase the cost of sewage treatment; while insufficient discharge will lead to poor denitrification and phosphorus removal effects. Summary of the Utility Model

[0004] Aiming at the problems raised in the above background art, the purpose of the present utility model is to provide a multi-carbon source dosing sewage treatment device.

[0005] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:

[0006] A multi-carbon source dosing sewage treatment device includes a support frame, a protective barrel is installed on the support frame, a water outlet is connected to the output end of the protective barrel, a carbon source barrel is rotatably installed on the protective barrel, a barrel cover is hingedly installed on the carbon source barrel, a buckle lock is installed between the barrel cover and the carbon source barrel, a plurality of water delivery pipes are uniformly installed at the bottom of the carbon source barrel in a ring shape, the water delivery pipes are communicated with the carbon source barrel, an upper electric butterfly valve is installed on the water delivery pipes, all the ends of the water delivery pipes are connected to an installation plate together, the installation plate is provided with threaded through holes communicating with the water delivery pipes, the threaded through holes are threadedly connected with metering pipes, the capacity of each metering pipe is different, the lower end of each metering pipe is threadedly connected with an installation pipe, and a lower electric butterfly valve is installed on the installation pipe;

[0007] A motor is installed on the installation plate, and a stirring blade is connected to the output end of the motor, and the stirring blade is placed inside the carbon source barrel.

[0008] Further defined, a control panel and a drag chain are installed on the protective barrel, and cables connecting the control panel to the upper electric butterfly valve and the lower electric butterfly valve are placed inside the drag chain. With such a design, the control panel is used for program input and modification, and the installation of the drag chain prevents the connection wires of the upper and lower electric butterfly valves from getting coiled.

[0009] Further defined, a sealed maintenance door is installed on the protective barrel. With such a design, the replacement of the metering pipe and the maintenance and replacement of components can be realized.

[0010] Further defined, there are at least four water supply pipes. With such a design, the quantity of metering is ensured and the scope of use is expanded.

[0011] Further defined, the upper electric butterfly valve and the lower electric butterfly valve have the same specification model. With such a design, it is conducive to the replacement of spare parts.

[0012] Advantages of adopting the present utility model:

[0013] With the structural design of the present utility model, the capacity of each metering pipe is different. Therefore, by only opening the metering pipe at the corresponding position, the addition of the carbon source contained in the metering pipe can be realized, achieving the purpose of quantification. Further, opening multiple metering pipes can also achieve an additive effect, expanding the scope of quantitative dosing;

[0014] With the structural design of the present utility model, under the effect of the motor, it is ensured that the carbon source in the carbon source barrel will not scale and oxidize, thereby ensuring the use effect. Brief description of the drawings
