Embodiment Construction

[0022] A kind of food waste wastewater treatment process, comprises the steps:

[0023] Oil separation and slag separation: the waste oil and waste residue are separated in the separation tank by centrifugation or gravity, and waste water is obtained;

[0024] Pretreatment: The wastewater flows into the pretreatment tank for coagulation, flocculation and neutralization in sequence;

[0025] Sedimentation: the waste water flows into the sedimentation tank for sedimentation treatment;

[0026] Hydrolysis and acidification treatment: the wastewater flows into the hydrolysis and acidification tank for treatment;

[0027] Anaerobic treatment: the wastewater flows into the anaerobic tank for treatment;

[0028] Aerobic treatment: the waste water flows into the aerobic pool for treatment;

[0029] Sedimentation: the waste water flows into the sedimentation tank for sedimentation treatment;

[0030] MBR membrane treatment: use MBR membrane to treat wastewater;

[0031] NR membran...

Abstract

The invention relates to the technical field of wastewater treatment, in particular to a kitchen waste wastewater treatment process and the process comprises the following steps: oil and slag separation: separating waste oil and waste slag in a separation tank under the action of centrifugation or gravity to obtain wastewater; pretreatment: allowing the wastewater to flowinto a pretreatment pool to be subjected to coagulation, flocculation and neutralization treatment in sequence; precipitation: enabling the wastewater to flow into a sedimentation tank for precipitation treatment; hydrolytic acidification treatment: enabling the wastewater to flow into a hydrolytic acidification tank for treatment; anaerobic treatment: enabling the wastewater to flow into an anaerobic tank for treatment; aerobic treatment: enabling the wastewater to flow into an aerobic tank for treatment; precipitation: enabling the wastewater to flow into the sedimentation tank for precipitation treatment; MBRfilm treatment: treating the wastewater by utilizing an MBR film; NR film treatment: treating the wastewater by using an NR film; and emission. The process has the advantage of environmental protection.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, more specifically, it relates to a kitchen waste waste water treatment process. Background technique [0002] Kitchen waste generally accounts for one-third of domestic waste. Although it is organic matter, it contains a lot of water, is not easy to incinerate, and has a large salt content, which makes it difficult to recycle. In particular, it has been accused of being the culprit of odor and leachate, and some landfills even refuse to accept treatment. [0003] However, with the soaring international feed and fertilizer prices, the demand for recycling food waste is gradually increasing. Farmers who have been refusing to use it before have gradually increased their attention to the food waste resource production products. [0004] The food waste resource treatment process generally involves heating, sterilization, drying, and crushing. The traditional method is to use crushers, ...
