Description
Technical field
The invention belongs to environmental technology field, be specifically related to the method for food enterprise sewage disposal.
Background technology
In food production, the cleaning etc. of various raw materials pretreatment and equipment will produce a large amount of waste water, to environment, so, wastewater treatment is one of main task of food factories design, and China's industrial wastewater discharge standard is that on January 1st, 1974 is tentative, within 1988, is changed to " sewage drainage standard " and replaces GB54-1973(waste water part), within 1996, be again changed to " integrated wastewater discharge standard " (GB8978-1996), on January 1st, 1998 comes into effect.China's industrial wastewater discharge standard regulation:
The water source of tap water and the water quality of landscape excursion district, forbid there is any pollution;
Fishery and agricultural water, ensure the growth conditions of plant, ensures that the remaining toxicity of objectionable impurities in animal and plant body must not exceed food sanitation standard;
The water source of process water, must meet the requirement of industrial process waters.
In emission standard, to the highest permissible discharge concentration containing objectionable impurities in trade effluent, make strict regulation.The highest permissible discharge concentration of objectionable impurities is divided into two classes: the first kind, can put aside in environment or animal and plant body, HUMAN HEALTH be produced to the objectionable impurities of long-range impact, the trade effluent containing this kind of objectionable impurities, at discharge of wastewater mouth place, the emission standard that should conform with the regulations could be discharged.
Equations of The Second Kind, its long-range impact is less than first kind objectionable impurities, that is, in the long run considers, its toxic action is lower than the toxicity of first kind material, and the concentration of narmful substance at its relief outlet place of factory should meet the requirements prescribed, and could discharge.
National sewage comprehensive emission standard not only defines the highest permissible discharge concentration of objectionable impurities in trade effluent, and defines the highest permission water displacement of part industry.
The parameter detecting the pollution level of water quality is as follows:
Detect the pollution level of water quality, except the highest permissible discharge concentration of the one or two class in regulation, also have a lot of indexs, sum up and can be divided into following three classes:
(1) pollution parameters of physics aspect: as transparency, turbidity, color, suspended substance, temperature, stink, taste, evaporation residue and specific conductivity etc.;
(2) pollution parameters of chemical aspect: as pH value, acidity, basicity, hardness, biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved oxygen, total organic carbon, total oxygen demand, oil-contg, nutrient content and harmful and noxious substance content etc.;
(3) pollution parameters of biological aspect: as virus, coliform number, bacterial count, toxicity of fish experiment and aquatic organism analysis etc.
The treatment process of sewage mainly contains following several:
The physical treatment method of waste water:
Physical treatment method utilizes physical action; suspended substance in waste water, oils, solubility salt and other solid are separated; thus protection subsequent disposal facility can normally run; reduce other treatment facility load, the physical treatment method of waste water is divided into two classes: namely every filter (as barrier, screen cloth, filtration, centrifugal etc.) be separated (as precipitated, floating etc.).
The chemical treatment method of waste water: the chemical treatment method of waste water adds certain chemical substance in waste water, utilize chemical reaction to be separated, reclaim some pollution substance in waste water, or make it be converted into harmless material, inorganic or organic (being difficult to biodegradable) dissolved substance mainly in water and waste water of its handling object or colloidalmaterial.Main method has chemical coagulation, neutralization, chemical precipitation and oxidation reduction process etc.
The bioremediation of waste water:
At occurring in nature, there is a large amount of microorganism relying on organism life, they not only can decompose the general organism of oxidation, and are translated into stable compound, and can also transform toxic organic compound.In fact, in the harmless process of trade effluent, not only utilize microbiological treatment organic poison, as phenol, aldehyde, nitrile etc., also for the treatment of the inorganic toxic material that microbial nutrition element is formed, as prussiate, sulfide etc., these materials itself to the toxic effect of microorganism, but form the element of these materials, some is needed for microbial nutrition, therefore they have duality to microorganism, and by the control of concentration, poisonous substance can become nutriment.
Biological treatment is exactly utilize this function of microbial decomposition oxidation of organic compounds, and take certain artificial measures, create and have the environment utilizing microorganism growth, breeding, microorganism is bred in a large number, to improve the method that it decomposes a kind of wastewater treatment of oxidation of organic compounds efficiency, biological treatment is divided into the aerobic and large class of anaerobism two, and Aerobic biological process needs the supply of aerobic, and anaerobic biological treatment then needs to ensure oxygen-free environment.
