Problems solved by technology

The disadvantage is: adding water to the anaerobic subsystem, resulting in an increase in processing capacity
Flocculation at the front end, a large amount of flocs are obtained after two times of dosing, causing secondary treatment problems
Chemical agent, using electric Fenton, high operating cost
The use of electric Fenton in high salt water quality produces harmful gas, which is harmful to human health

Abstract

The invention discloses a swill filtrate resourceful treatment system, which comprises a front-section treatment unit, an A2O process, an AB process, a rear-section treatment unit and a resourceful treatment unit. The salt-tolerant composite strains are treated under facultative acid, medium-temperature anaerobic and aerobic alkaline conditions, and generated flocculent sludge is fermented in an anaerobic environment to prepare a decomposed liquid fertilizer, so that resource utilization is achieved. The swill filtrate resourceful treatment system is stable in process and low in operation cost, can effectively solve the potential threat to the body health of people due to improper utilization of the catering swill, utilizes the catering swill to produce the organic fertilizer, turns wasteinto wealth and performs harmless treatment, and creates a new technology taking microbiological treatment as a core for resource utilization of the catering swill in China. The life health of peopleis guaranteed and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of swill water treatment, in particular to a swill water filtrate resource treatment system. Background technique [0002] The urban dining swill filtrate has the characteristics of high salt, animal and vegetable oil content in the kitchen waste. At present, the urban swill filtrate is insufficient in the treatment of the urban swill filtrate, which is lower than the urban swill salt and animal and vegetable oil. Cities that do not separate food waste for separate classification generally use centralized landfill to collect and landfill food waste and domestic waste together. Influenced by the large water content of kitchen waste, in the process of landfill treatment, kitchen waste will produce a large amount of organic wastewater due to fermentation and corruption, which will cause serious harm to the groundwater source and soil environment of the garbage dump. The corruption of kitchen waste will produce...
