Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] as follows figure 1 As shown, a food waste wastewater pretreatment system includes an oil-separating sedimentation tank 1, a regulating tank 2 and a demulsification coagulation air flotation and slag removal device. One end of the oil-separating sedimentation tank 1 is provided with a garbage fermentation wastewater inlet pipe 4. The other end is connected to the regulating tank 2 through the outlet pipe 5, and an oil slick removal device is arranged in the oil-separating sedimentation tank 1; One end is the water outlet and the water outlet is connected to the demulsification coagulation air flotation and slag removal device through the lifting pump 6 and the water outlet lifting pipeline 7. The water outlet of the regulating pool is also provided with a temperature probe 8 and an outlet water temperature control device. The position of the water inl...

Abstract

The invention discloses a pre-treatment system for kitchen waste water. The system is characterized by comprising an oil separating settling pond, an adjusting pool and a demulsifying, coagulating, air-floating and deslagging device, wherein a waste fermenting wastewater inlet pipe is arranged at one end of the oil separating settling pond while the other end of the oil separating settling pond is connected with the adjusting pool through a water outlet pipe, and the oil separating settling pond is internally provided with an oil slick removing device; one end of the adjusting pool is a water inlet end connected with a water outlet pipe of the oil separating settling pond while the other end of the adjusting pool is a water outlet end which is connected with the demulsifying, coagulating, air-floating and deslagging device through a lifting pump and a water outlet lifting pipeline; a temperature probe and a water outlet temperature regulating device are further arranged at the water outlet end of the adjusting pool. The system disclosed by the invention is designed for particularity of kitchen waste water components and can efficiently and quickly realize pre-treatments, such as deoiling, adjusting and oil slick cleaning, of kitchen waste water, so that the treated sewage can be suitable for subsequent conventional sewage treatment steps, thereby alleviating the demand on subsequent sewage treatment process and improving the final treatment effect of kitchen waste water.

Description

technical field [0001] The invention relates to a kitchen garbage wastewater treatment technology, in particular to a kitchen garbage wastewater pretreatment system. [0002] Background technique [0003] People produce all kinds of waste and garbage in urban life from time to time. Among them, kitchen waste refers to the waste left over from the kitchen processing ingredients, and fruit and vegetable waste mainly refers to all kinds of discarded fruits and vegetables produced in the fruit and vegetable market. Garbage, both types of garbage have the characteristics of mainly organic matter. Since the domestic waste treatment technology is still at a relatively low-level development stage, the existing kitchen waste fruit and vegetable waste is generally not classified, and is transported to the landfill together with ordinary waste. Such treatment will cause great environmental pollution, not only generate The leachate will pollute the groundwater, and the methane and str...
