Background
With the development of cities, a large amount of sewage is generated in cities, the sewage is conveyed to a sewage treatment plant for treatment, and the sewage and the sludge which meet the standard are obtained after treatment, wherein the discharged water can be directly discharged into ditches, the sludge contains a large amount of pathogenic bacteria and metals, if the sludge is also discharged into the ditches, the metals permeate into the underground water to pollute the water resources, and meanwhile, the bacteria permeate into the underground water to pollute the water resources.
The existing sludge treatment device is adopted to remove metals and pathogenic bacteria in sewage, the treated sludge contains various rich trace elements, and the sludge can improve the soil structure, increase the soil fertility and promote the growth of crops after being applied to farmlands. This kind of sludge treatment equipment is including a jar body, set up in the motor at jar body top, and the output shaft of motor stretches into in jar internal, and output shaft department has the (mixing) shaft through the coupling joint, installs a plurality of blades on the (mixing) shaft, and the bottom of jar body is provided with the sludge discharge port, and the bottom of sludge discharge port is connected with the butterfly valve, and the top of jar body is provided with the mud inlet port and adds the medicine mouth. When the electric stirring machine works, the motor is firstly turned on, the motor drives the stirring shaft to rotate, and the stirring shaft drives the blades to rotate; under the stirring state, sludge is introduced into the tank body through the sludge inlet, meanwhile, the sludge and the agent A are introduced into the tank body through the agent adding port through the agent A, after a certain amount of sludge is introduced, the introduction of the sludge and the agent A is stopped, the agent A and the sludge are mixed through the blades, pathogenic bacteria in the sludge are killed by the agent A, after a period of time, a certain amount of agent B is introduced into the agent adding port, the agent B and the sludge are mixed, the agent B removes metals in the sludge, after a period of time, sludge which can be applied to soil to promote the growth of crops can be obtained, and finally, the butterfly valve is opened to discharge the sludge from the tank body.
However, although this sludge treatment apparatus can treat municipal sludge, the following drawbacks still exist: 1. the blades do single circumferential movement, so that long time is required for uniformly mixing the sludge with the medicament A or the medicament B, pathogenic bacteria and metals are treated thoroughly, and the treatment efficiency of the sludge is reduced. 2. Since the sludge has a large viscosity and a poor fluidity, it takes a long time for the sludge to be discharged from the butterfly valve after the butterfly valve is opened, thereby reducing the sludge treatment efficiency. 3. A large amount of sludge is attached to the inner wall of the tank body, and the volume space of the tank body is gradually reduced along with the long-term use of the tank body, so that the sludge treatment capacity is reduced. 4. The sludge discharged from the butterfly valve is very smelly, and once the sludge is applied to soil, the smell pollutes the surrounding air, which is very environmentally unfriendly. Therefore, there is a need for a sludge treatment system that can improve the efficiency of sludge treatment, increase the amount of sludge treated, and effectively remove odor from sludge.
