Description

A kind of process regeneration application system of food and drink waste water
Technical field
This utility model relates to Restaurant Wastewater Treatment Technology field, is specifically related to the process regeneration application system of a kind of food and drink waste water.
Background technology
Along with the continuous quickening of urbanization process, hotel, hotel, dining room scale expanding day, quantity is increasing, the food and drink waste water amount produced therewith is also increasing, according to incompletely statistics, the undressed waste water of China's annual catering trade discharge reaches more than one hundred million ton, and has ever-increasing trend.According to another document announcement, food and drink waste water discharge capacity accounts for the 3% of city domestic sewage discharge capacity, but its BOD5And CODcrContent but account for the 1/3 of total load, it is seen that Restaurant Industry Wastewater is high density pollution source, is the contaminated one of the main reasons of peri-urban water body.On the other hand, China is as " poor-water country ", and water resources crisis is increasingly serious; and there is the phenomenon that serious distribution of water resources is uneven; cause the shortage of many urban waters, not only limit the development of urban economy, and the living standard of resident is caused strong influence.Therefore, the process of food and drink waste water, regeneration can not only obtain significant environmental benefit, have more great economic benefit and social benefit.
The complicated component of food and drink waste water, content of organics is high, with Organic substances such as starch based, dietary fiber class, Animal fat classes for main component, has that nutritional labeling height, moisture content be high, oils and fats and a feature such as salt content fermentation high, perishable is smelly.Current domestic commonly used " coalescence ", " biological contact oxidation process " and " electrochemical process " etc. science and engineering skill, also has " stiffener plate film biological treatment ", but still there is problems in that
The process equipment adopting " coalescence ", " electrochemical process " etc. to be main body can only remove some materials such as suspension, insoluble silt particle; the hardly degraded organic substances such as the starch, the Animal fat that are dissolved in the water cannot be removed; such recirculated water arises that water quality blackout fouls in use for some time, it is impossible to ensure the stable operation of system.
" biological contact oxidation process " the process equipment of employing easily occurs that filler blocks, and water distribution and aeration are not easily uniform, and the problems such as dead angle occurs in local.It is complicated that filler arranges the structure making oxidation pond, is unfavorable for that equipment is installed and safeguards, and filler selects improper meeting to have a strong impact on treatment effeciency.
There are the following problems to adopt the process equipment that " biological treatment of stiffener plate film " is main body:
(1) pretreatment is higher to the requirement of equipment and materials, it is necessary to high temperature resistant, high pressure, and corrosion-resistant, and therefore cost of equipment is big, and the one-time investment of system is high;
(2) oxidizing process may produce the intermediate product that toxicity is stronger, be unfavorable for follow-up biochemical treatment;
(3) stiffener plate membrane bioreactor packed density is little, and floor space is big;Flat board diaphragm is easily broken, and after flat board diaphragm breakage, whole film must be changed, and repair and maintenance need to set up large lifting equipment when taking out, and hangs out module, operating difficulties.
(4) recycled water can not meet " urban sewage reutilization urban reclaimed water water quality " (GB/T18920-2002) and flushes the toilet regulation in project: colourity (≤30), turbidity (≤5), total residual chlorine (after contact 30min >=1.0mg/L, pipe network end >=0.2mg/L), total coli group (≤3/L) index request.
