Embodiment 1

[0052] This embodiment provides a kind of food waste wastewater treatment system, such as figure 1 As shown, it includes a slurry tank 1, a three-phase separation unit 4, a regulating tank 3, an air flotation tank 5 and a biochemical tank 6 which are connected in sequence.

[0053] The slurry tank is provided with a water inlet 11 , a water outlet 12 and a sludge inlet 13 . The water inlet 11 is to allow the kitchen waste wastewater to be treated to enter the slurry tank, the water outlet 12 is to discharge the kitchen waste wastewater mixed with the activated sludge into the three-phase separation unit 4, and the sludge inlet 13 It is to discharge the activated sludge in the scraping tank 1 into the slurry tank 1. In the slurry tank 1, the kitchen garbage wastewater is fully mixed with the activated sludge, which can remove the odor in the kitchen garbage wastewater and absorb the oil phase in the wastewater.

[0054] The three-phase separation unit 4 can be one of a three-...

Embodiment 2

[0061] This embodiment provides a process for treating kitchen waste and wastewater, using the system provided in Example 1, the specific process is as follows:

[0062] Firstly, the kitchen waste wastewater to be treated is discharged into the slurry tank 1 through the water inlet 11 of the slurry tank 1 . In the initial stage of the process, municipal sludge needs to be added. After the system runs stably, the scraping slag produced in the air flotation tank 5 and the sludge produced in the biochemical tank 6 can meet the demand for the use of activated sludge in the deodorization stage; in the slurry tank 1 Every cubic meter of kitchen waste wastewater is fully mixed with every cubic meter of activated sludge (stabilized sludge produced after domestication of sludge from municipal sewage plants) by stirring.

[0063] The mixed liquid is discharged into the three-phase screw dehydrator through the water outlet 12 of the slurry tank 1 and mixed with 1mg (per ton of water) pol...

Embodiment 3

[0068] This embodiment provides a process for treating kitchen waste and wastewater, using the system provided in Example 1, the specific process is as follows:

[0069] Firstly, the kitchen waste wastewater to be treated is discharged into the slurry tank 1 through the water inlet 11 of the slurry tank 1 . In the initial stage of the process, activated sludge needs to be added. After the system runs stably, the scraping slag produced by the air flotation tank 5 and the sludge produced by the biochemical tank 6 can meet the requirements for the use of activated sludge in the deodorization stage; Every cubic meter of food waste wastewater is fully mixed with every cubic meter of activated sludge (stabilized sludge produced after domestication of sludge from municipal sewage plants).

[0070] The mixed liquid is discharged into the feed port of the screw stack separator through the water outlet 12 of the slurry tank 1 and mixed with 1 mg (per ton of water) polyaluminium chloride...

Abstract

The invention belongs to the technical field of kitchen waste wastewater treatment, and particularly relates to a kitchen waste wastewater treatment system and a treatment process thereof. The system comprises a residue slurry tank, a three-phase separation unit, an adjusting tank, an air floatation tank and a biochemical tank which are communicated in sequence, and the slag slurry tank is used for mixing kitchen waste wastewater to be treated with activated sludge. The residue slurry tank can control odor before the kitchen waste water enters the treatment process and is convenient for dehydration separation, the activated sludge and the kitchen waste water can adsorb the oil phase in slurry after being combined, and the kitchen waste water is mixed with the sludge and a first flocculating agent, so that the dehydration efficiency can be further improved. The system can control the odor in the kitchen waste wastewater, and simplifies the treatment process of the kitchen waste wastewater.

Description

technical field [0001] The invention relates to the technical field of kitchen garbage wastewater treatment, in particular to a kitchen garbage wastewater treatment system and a treatment process thereof. Background technique [0002] With the rapid development of the economy and the continuous increase of the population, the pollution of water resources is also becoming more and more serious. Among them, kitchen waste wastewater is a common type of wastewater, and its annual production is also increasing. Kitchen waste wastewater is mainly wastewater generated from the treatment of food waste. If it is not treated effectively and discharged directly, it will cause serious damage to natural water bodies and society. The environment is seriously polluted, and the quality of kitchen waste wastewater is complex, with the characteristics of high organic matter concentration, high ammonia nitrogen content, high sulfide, etc., making it difficult to treat. [0003] The existing k...
