Description

[0001] Waste treatment equipment [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waste treatment apparatus for waste treatment such as sludge and food waste generated in the treatment of drinking water of domestic sewage, sewage or industrial wastewater, that is,

Background Art [0002] Various treatment apparatuses have been developed and used for the reduction of resources and the recycling of wastes such as sludge and food wastes generated in water treatment processes such as sewage, sewage or industrial wastewater.

Such a waste treatment apparatus uses a physical or chemical pretreatment apparatus. For example, the sludge reduction is performed by a physico-chemical treatment method and a biological treatment method depending on the characteristics of the wastewater.

The physico-chemical treatment process of the electron is a process to treat wastewater which has a high suspended solids concentration, a low organic matter concentration, and a heavy metal content. The treatment sequence is screen, flow control tank, mixing tank, PH tank, flocculation tank, , Filter paper, adsorption facility, and oxidation facility.

These physicochemical treatment apparatuses are relatively bulky and not economical.

Thus, recently, it is an eco-friendly method that enables biologic treatment using the latter microorganism preparation, including a mixed microorganism capable of decomposing sludge collected in order to prevent water pollution and reduce nitrogen and phosphorus in the water treatment process Biological treatment methods for reducing microbial agents, sewage and various pollutants, and nitrogen and phosphorus in wastewater can be heard.

However, in this biological treatment, waste water with a high BOD is treated, and the treatment process is performed in the following order: screen, flow rate regulator, PH regulator, biological treatment, tea settling, filtration, and discharge.

The complex wastewater treatment process is a case where both physicochemical treatment and biological treatment are performed simultaneously. When there are harmful substances affecting the microorganisms in the wastewater or when the pollution load is very high, biological treatment after primary physicochemical treatment .

Therefore, if FLOC is light according to the water quality of the wastewater, or if there are many N-H extractive substances, flotation tank is adopted and in the opposite case, sedimentation tank is adopted. At this time, the treatment process is carried out in the order of screen, flow rate adjusting tank, mixing tank, PH adjusting tank, flocculation tank, primary settling tank (float tank), biological treatment, secondary settling tank and discharge tank.

After the physicochemical treatment process or the biological treatment process, filtration water and sludge are essentially generated. Since the treatment of sludge having a relatively large amount of water is not easy, it is the main cause of secondary environmental pollution.

Due to such sludge, the cause of the environmental pollution as described above is being increased. Up to now, the technology has not achieved satisfactory treatment efficiency in various kinds of sludge treatment, and thus much research and development are required.
