Garbage wastewater treatment device with self-cleaning function

Abstract

The invention provides a garbage wastewater treatment device with a self-cleaning function. The device comprises a tank body, wherein one ends of a water feeding pipe and a water discharge pipe are fixedly connected to two ends of the tank body close to the upper end; the other end of the water feeding pipe is fixedly connected with a water supply device; the other end of the water discharge pipeis fixedly connected with a water-feeding device; the upper end of the tank body is fixedly connected with a sediment collecting box. Sedimentation in a sedimentation tank can be automatically extracted, securing continuous production, and effectively removing wastewater residual in sediments. After a garbage wastewater sedimentation process is completed and the sedimentation tank is idle, cleaning water is pumped into a cleaning frame through a cleaning water pump box, so that strong cleaning water flow is left along the side wall and the bottom of the sedimentation tank, the cleaning work ofthe sedimentation tank is automatically completed, and the garbage wastewater treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of garbage and wastewater treatment equipment, more specifically, to a garbage and wastewater treatment device with a self-cleaning function. Background technique [0002] In recent years, with the continuous development of my country's urbanization process, urban waste is also increasing at an average annual rate of 8% to 10%, while the growth rate in megacities is as high as 15% to 20%. In 2010, my country's municipal solid waste reached 264 million tons, and it is expected to be 409 million tons in 2030 and 528 million tons in 2050. At present, due to the constraints of economic and technological factors, the garbage disposal in my country still adopts sanitary landfill. As far as big cities are concerned, each city has multiple harmless waste treatment facilities, and landfill accounts for 91%. However, during the landfilling process, garbage and wastewater will be generated that threaten the surrounding water s...

Problems solved by technology

The content of heavy metal ions is high, mainly including more than ten kinds of heavy metal ions such as Fe, Zn, Cd, Cr, Hg, Mn, Pb, Ni, etc. Due to the characteristics of waste water itself, it is difficult to treat waste water

At present, the domestic garbage wastewater treatment process is not perfect and economical and efficient. During the garbage wastewater treatment process, the impurities in the garbage wastewater are easy to form dirt on the side wall and bottom of the treatment device container, especially the sedimentation tank that is often used as a garbage wastewater treatment container. Because a large amount of insoluble impurities are deposited here, the sediment needs to be cleaned frequently, and the inner wall of the sedimentation tank needs to be cleaned after the sediment is taken out. The prior art is mostly used to clean the sedimentation tank manually, which consumes a lot of labor and increases the cost. The cost of waste water treatment is increased, and because the sediment contains a large number of germs and toxic heavy metals, it is not conducive to the health of the staff
