Description
Technical field
The present invention relates to a kind of removable food and drink Waste Water Treatment.
Background technology
Along with the raising of the living condition of people, changing food waste more and more causes very large harm to our living environment, and the Pollutant levels in changing food waste high-concentration waste water are higher, and mainly organism, grease in waste water, protein content are higher, coliform content severe overweight.Changing food waste is after pre-treatment, anaerobic treatment, and in its waste water, concentration of suspension is higher, and COD is up to 20000 ~ 30000mg/L, BOD at 5000 ~ 10000mg/L, and waste strength is high, and intractability is large.
Sewage treatment process is divided into coagulation, second-stage treatment and tertiary treatment.For food and drink waste water, coagulation is generally adopt solid-liquid separation technique to remove suspended substance in sewage and floating matter; Second-stage treatment is main processes, and the general biologic treating technique that adopts removes the toxic substances such as Organic substance in water, generally adopts the technology such as membrane processing method, strong oxidizer to be evolved further by sewage.
Existing food and drink waste water process, process mainly through the fixed wastewater treatment equipment of pipeline transportation to waste water treatment plant, its action method is: the waste water produced at food and drink waste water water source introduces the wastewater treatment equipment of waste water treatment plant by pipeline, then carries out purifying treatment to waste water.The subject matter that this kind of mode exists is: be not suitable for dispersion, waste water water source that blowdown flow rate is little carries out wastewater treatment.
In addition, in food and drink waste water treating processes, coagulation is a very important link.It effectively can remove the solid pollutant in suspension in sewage, makes it sedimentation occurs.Food and drink waste water has suspended substance, fat content is high, and heavy metal ion is many, COD and BOD numerical value is large, water quality and water yield vary within wide limits, and nitrogen, phosphorus compound content are high, in some cases water temperature also comparatively high.The kind of coagulating agent is also varied, selects suitable coagulating agent to carry out process to sewage of different nature and can play certain specific aim and better coagulation effect.
Coagulating agent can promote that colloidal particle and other suspended particle are condensed into unformed coagulum and precipitate, and is chemical reagent necessary in a kind of sewage treatment process.The water quality of present sewage is complicated, and original single flocculation agent is difficult to the requirement meeting water treatment, and therefore compound coagulant has become the focal point of people, and compound coagulant not only remains original advantage, and also enhances coagulation performance due to synergistic effect.Based on the chemical constitution of compound coagulant, compound coagulant can be divided into inorganic-inorganic compound coagulant, inorganic-organic composite coagulant and organic-organic composite coagulating agent.With regard to concrete treatment effect, inorganic-organic hybrid high-molecular coagulant adopting is relatively good.Inorganic polymer coagulant is strong to the water treatment suitability of various complicated ingredient, and cost is low, but it is little to generate flco, and dosage is large, generates sludge quantity large.By contrast, organic polymer coargulator can be with the hydrophilic radicals such as-COO-,-NH-,-OH, can have a various structures such as chain, ring-type, be beneficial to pollutent and enter flco, have institute's expense few, form the advantages such as floc sedimentation is large, residual sludge easily processes, decolourising property is good.Both are combined the result of use that effect is better than single flocculation agent.
