Description
Technical field
The utility model belongs to kitchen garbage, waste-water processing technology field, is specifically related to a kind of kitchen garbage, waste-water treatment unit.
Background technology
Kitchen garbage, waste-water, excrement and urine water belong to CODcr and BOD
5content is high, the high concentrated organic wastewater of good biodegradability, and along with the progressively raising of China's resident living level, the wasting phenomenon on dining table is on the rise, changing food waste generation increase sharply [1].Because changing food waste is solidliquid mixture, so while processing, should first liquid kitchen waste water and solid-state meal kitchen be separated, then respectively solids and liquid waste water are processed.At present, Chinese scholars is to the research of changing food waste mainly around the processing of solid-state changing food waste and launch, and the processing of liquid towards kitchen waste water rarely has report.So the efficient processing of liquid kitchen waste water, has great importance for the innoxious and resource utilization of changing food waste.Because fat content in kitchen waste water is higher, and the grease of high-content can cause adverse influence to subsequent disposal.So when it is processed, generally first adopt that certain technology will wherein grease be separated with waste water, isolated grease carries out recycling, and degrease wastewater treatment enters urban pipe network after up to standard.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of kitchen garbage, waste-water treatment unit, has feature simple in structure, that wastewater treatment is simple, processing efficiency is high.
To achieve these goals, the technical solution adopted in the utility model is: a kind of kitchen garbage, waste-water treatment unit, include equalizing tank, equalizing tank is connected with denitrification pond by UASB+ membrane bioreactor, denitrification pond is connected with nitrification tank, nitrification tank is connected with ultra-filtration membrane purifying processor, and UASB+ membrane bioreactor, denitrification pond, nitrification tank, ultra-filtration membrane purifying processor are all connected with the input aperture of mud storage pool, and mud storage pool is also connected with the entrance in denitrification pond with water extracter.
The biogas mouth of described UASB+ membrane bioreactor is connected with methane utilization device.
The beneficial effects of the utility model are:
Waste water after the utility model UASB processes, flooding quantity is pressed 30m
3/ h meter, influent COD cr content is 40000mg/L, and water outlet CODcr content is less than 12000mg/L, and clearance is greater than 70%, water inlet BOD
5content be 24000mg/L, water outlet BOD
5content be less than 7500mg/L, clearance is greater than 70%, water inlet NH
3-N content is 2000mg/L, water outlet NH
3-N content is less than 3000mg/L, and water inlet SS content is 6000mg/L, and water outlet SS content is less than 1800mg/L, and clearance is greater than 70%;
Pass through+Membrane Bioreactor for Wastewater Treatment, flooding quantity is pressed 30m again
3/ h meter, influent COD cr content is 12000mg/L, and water outlet CODcr content is less than 240mg/L, and clearance is greater than 80%; Water inlet BOD
5content be less than 7500mg/L, water outlet BOD
5content be less than 150mg/L, clearance is greater than 80%; Water inlet NH
