The restaurant wastewater treatment device is simple in structure, reasonable in design, convenient for operation and low in manufacturing cost and running cost, ensures the quality of effluent obtained by treating oily restaurant wastewater can meet the regeneration and reuse standard, and can realize the popularization and the application of the restaurant wastewater treatment and reuse technology.
Description
Technical field
The utility model relates to the saprobia chemical treatment and sewage recycling utilizes technical field, is meant a kind of food and drink waste water treatment unit especially, is applicable to waste water on-the-spot disposal such as restaurant, restaurant, dining room, dining room.
Background technology
Food and drink waste water is meant the undressed waste water by the catering trade discharging.Be characterized in containing in the waste water a large amount of colloidal particles and suspended substance, main component is animal-plant oil, inorganic salinity, tensio-active agent and protein etc.According to the statistics made by the departments concerned, nearly hundred million tons of the undressed waste water of the annual catering trade discharging of China, and ever-increasing trend is arranged.General food and drink waste water quantity discharged accounts for 3% of city domestic sewage quantity discharged, but its BOD
5And COD
CrContent but account for 1/3 of total load, the result who catering trade sewage effluent contamination index is detected according to domestic several main big cities shows: COD is 1～4mg/L, BOD is 300～400mg/L, SS is 300～400mg/L, grease is more than 150mg/L, as seen food and drink waste water is the high density pollution source, is the contaminated one of the main reasons of peri-urban water body.These concentration of organic wastewater height, the pre-treatment rate is on the low side, and is unprocessed or handle the below standard urban pipe network that just enters, and will pose a big pressure to the municipal sewage plant.In the supporting incomplete area of pipe network, problem is more serious.Food and drink waste water directly enters near water body, not only influences environment, and harm people's physical and mental health.
The conventional process food and drink waste water has physico-chemical processes, electrochemical process and biological treatment.Physico-chemical processes mainly comprises coarse method, breakdown of emulsion method, Coagulation Method and magnetic adsorption method of separation etc.; exist treatment effect to have than great fluctuation process with change of water quality; processing efficiency is not high, also exists the safety issue of potential chemical medicinal residue thing simultaneously, can't generally promote.
Though the comparatively sophisticated method of electrochemical process, its power consumption is big, and with the increase of waste strength, current consumption also can obviously increase, and instrument and equipment is also had certain corrodibility.
Present biological process mainly contains activated sludge process, biomembrance process, biological contact oxidation process and biological degradation method etc.Activated sludge process is as using sewage disposal technology the most widely, treatment effect is better, easy and simple to handle, but its floor space is big, the mud generation is big, and owing to contain a large amount of tensio-active agents in the food and drink waste water, makes that the situation of sludge bulking is very outstanding, and the expense height has certain restriction on using.
Summary of the invention
At the problems referred to above, the utility model is developed a cover cost-effective food and drink waste water treatment unit-air supporting-BAF method food and drink waste water treatment unit, advantage in conjunction with physico-chemical processes and biological process, under the prerequisite that guarantees treatment effect, overcome sludge bulking, reduce construction investment and working cost.
The utility model is realized by following technical solution:
A kind of food and drink waste water treatment unit comprises air flotation pool, aeration and biological pond, clean water basin, sterilization equipment and blast aeration system composition.
Described air flotation pool is a vertical-flow air flotation pond, adopts the pressurized dissolved air flotation mode.
Described BAF is a rectangle or bulge, inner filtrate and the aerating apparatus installed.
Described blast aeration system comprises gas blower, gas pipe line and aerating apparatus composition.
Described air flotation pool, BAF, clean water basin can adopt integral type to arrange, do not need connecting pipe, save floor space and construction investment.
Described air flotation pool, BAF, clean water basin, sterilization equipment and blast aeration system can adopt sledge dress form, further save floor space and construction investment.
Have suspension microorganism and attached microbial in the described BAF simultaneously, the microorganism total amount is big in the unit volume, and food chain length, bacterial classification enrich, and capacity of resisting impact load is strong, effectively overcomes the generation of sludge bulking.
In the utility model, sewage enters into a large amount of total phosphorus, suspended substance and the oils that air flotation pool removes decontaminated water through water inlet pipe, remove ammonia nitrogen and organism through BAF, enter clean water basin, as buffering and storage, water outlet can be afforested in lavatory flushing and near place by direct reuse after the sterilization equipment sterilization.This technological operation is simple, and floor space is little, convenient management.The utility model adopts air supporting-biological aerated filter process, can effectively remove suspended substance, overcomes ordinary activated sludge process sludge expansible problem, the advantage that has biomembrane process simultaneously, reduce excess sludge production, make the system can steady running, be easy to safeguard.
The utility model has been realized the combination of air supporting, biological aerated filter process, when improving processing efficiency, has realized saving land, the energy-conservation and purpose that reduces discharging.The utlity model has following advantage:
1, structure of reactor compactness of the present utility model, structure is succinct, and operation is simple with maintenance.
2, the utility model adopts integral type sledge assembling structure, has effectively saved floor space.
3, there are microbial film and active sludge simultaneously in the BAF of the present utility model, thereby can improve biomass greatly, for nitrifier, denitrifying bacteria and dephosphorization bacterial provide suitable life condition, and then improve sewerage dephosphorization and denitrification effect, reduce construction investment and working cost.
4, the utility model does not need mixed-liquor return and mud to reflux, and has saved power consumption;
5, the microorganism generation cycle in the BAF long, sludge output is few, has saved sludge treatment equipment, help energy-conservation with save land.
In a word, a kind of food and drink waste water treatment unit of the present utility model adopts integrated sledge installing meter, adopt air supporting+biological aerated filter process, realize the resource utilization reuse of food and drink waste water, not only can improve processing efficiency, and save initial cost and working cost effectively, be a kind of Sewage treatment systems with very high practical value.
