Problems solved by technology

[0003] Based on the basic characteristics of food waste wastewater, it is almost impossible to use one treatment process alone to achieve the ideal treatment effect. At present, the treatment of food waste wastewater is mostly based on its water quality characteristics combined with the actual treatment engineering, and chooses different technical methods to implement the combination. However, due to the complex composition of food waste wastewater, it is difficult to find a widely applicable treatment system and process. In addition, food waste water is mostly produced in the process of squeezing waste transfer stations, and traditional civil engineering construction is not suitable for environmental protection buildings / structures. Its investment is large and it covers a large area. At present, there is an urgent need for a kitchen waste wastewater treatment system that is easy to install and low in investment.

Embodiment 1

[0069] A modular food waste wastewater treatment process and its system, which is divided into the following units: disc solid-liquid separator 1, regulating tank 2, heating tank 3, oil and slag removal centrifuge 4, neutralization device 5, sludge Dehydrator 6, phosphorus removal integrated device 7, super oxidation device 8, water distribution tank 9, anaerobic tank 10, multi-stage AO-MBR device 11, disinfection and decolorization device 12,. These units are connected by pipelines to form the treatment system of the present invention.

[0070] Specifically, the disk solid-liquid separator 1 is a solid-liquid separation device, which is provided with a water inlet, a water outlet and a slag outlet, and the water outlet is connected to the regulating tank 2 through a pipeline.

[0071] The adjustment tank 2 is a waste water homogenization unit whose size matches the change cycle of waste water. The bottom is provided with a stirring air pipe and equipped with a fan.

Embodiment 2

[0083] The present invention is applied to a leachate treatment demonstration project of a food waste transfer station in Shanghai. The daily treatment capacity is 100t. After treatment, the effluent of the leachate can reach the "Urban Sewer Discharge Standard (GB / T31962-2015)", each process The processing effect of the unit is shown in the table below:

[0084] Table 1 Operational water quality data of a leachate treatment demonstration project in a food waste transfer station

[0085]

[0086]

[0087] Note: The above table is the average value during operation.

[0088] As can be seen from the data in Table 1, the present invention has a good effect on the treatment of kitchen waste and wastewater, and most of the pollutants are removed, all of which can be discharged up to the standard.

[0089] In summary, compared with the prior art, the system and process provided by the present invention have good energy-saving performance, high degree of resource recovery, goo...

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a modular kitchen waste wastewater treatment process and system thereof. Background technique [0002] With the rapid development of my country's economy, the living standards of the people have also been continuously improved, which has brought about a substantial increase in domestic waste. Among them, kitchen waste is an important component of urban domestic waste. According to relevant statistical studies, kitchen waste accounts for Most of the municipal solid waste accounts for more than 50%. Due to the characteristics of eating habits in our country, the food waste has a high moisture content and a large proportion of organic matter. The waste water produced by the food waste is rich in organic matter such as animal and vegetable oils, proteins and amino acids. The characteristics of high concentration, high salinity, various types, and high difficulty in processing have a...
