Abstract
The invention relates to a method for treating food wastewater, and belongs to the technical field of wastewater treatment. The invention provides a method for treating the food wastewater with simpleoperation, good treatment effect and the effluent can be discharged directly. The method comprises the following steps that: (1) the wastewater enters a bar screen firstly to remove suspended matters; (2) the effluent enters an adjusting tank for storing, homogenizing and adjusting the wastewater; and (3) the effluent enters an anaerobic bio-filter reactor for biological treatment, the wastewaterenters the bio-filter reactor from a lower water inlet and flows through a sludge section, a packing section and a three-phase separation section orderly, methane gas is led out from the three-phaseseparation section, and anaerobic organism strains cultured in the biological treatment process in the anaerobic bio-filter reactor comprise hydrolytic bacteria, acidification bacteria and methane bacteria; and (4) the effluent enters a sedimentation tank to remove the suspended matters, and is discharged after reaching a standard.
Description
Technical field
The invention belongs to technical field of waste water processing, particularly a kind of treatment process of food wastewater.
Background technology
Trade effluent is meant waste water, sewage and the waste liquid that produces in the Industrial processes, wherein contains the pollutent that produces in the industrial production materials, intermediate product and the product that lose with current and the production process.Along with developing rapidly of industry, the kind and the quantity of waste water rapidly increase, and is also extensive day by day and serious to the pollution of water body, threatens human beings'health and safety.The trade effluent classification has following three kinds usually: first kind is the chemical property classification by contained principal pollutant in the trade effluent, and containing inorganic pollutant is the main inorganic wastewater that is, containing organic pollutant is the main organic waste water that is.Second kind is product and the processing object classification by industrial enterprise, as metallurgical waste water, paper waste, coke-oven gas waste water, metal pickling waste water, chemical fertilizer waste water, textile printing and dyeing wastewater, waste water from dyestuff, leather-making waste water, agricultural chemicals waste water, power station waste water etc.The third is by the classification of the main component of contained pollutent in the waste water, as acid waste water, alkaline waste water, cyanide wastewater, chromate waste water, cadmium wastewater, mercury-containing waste water, phenolic wastewater, oily(waste)water, contain organophosphorus waste water and radioactive wastewater etc.Produce the waste water that produces in the food process and just belong to organic waste water.This class wastewater treatment method mainly contains: physics method, chemical method, catalytic oxidation, biochemical process etc., in waste water treatment engineering, adopt traditional biochemical process, mostly as A/O method, A
2/ O method or improved thus technology.Activated sludge process in wastewater biochemical technology is present the most frequently used organic waste water bioremediation.These Technologies are in handling the lower city domestic sewage of organic loading (COD), ammonia nitrogen, obtain remarkable effect, but be applied to then occur in the treatment of Organic Wastewater engineering many insoluble problems----organic loading more much higher than sanitary sewage, the phenol content that bio-toxicity is bigger, exceed the ammonia-nitrogen content of several times even tens of times, this makes numerous design library part editor and reuses be difficult to operation up to standard.
Summary of the invention
The invention provides a kind of simple to operate, treatment effect good and the treatment process of a kind of food wastewater that water outlet can directly be discharged.
The invention provides a kind of treatment process of food wastewater, comprise following step:
(1) waste water is introduced into grid and removes suspended substance;
(2) water outlet enters equalizing tank, to waste water store, homogeneous and adjusting;
(3) water outlet enters anaerobe filter bed reactor and carries out a biological disposal upon, bio-filter bed reactor passes through mud section, packing section, three phase separation section successively by following water-in water inlet upper reaches, draw methane gas in the three phase separation section, the anaerobe bacterial classification that carries out cultivating in the biological treatment process at anaerobe filter bed reactor comprises: hydrolysis bacterium, acidifying bacterium, methanobacteria;
(4) water outlet enters settling tank, removes suspended substance, the water outlet qualified discharge.
The present invention has following beneficial effect: to organic matter removal efficient height, floor space is few, and technology is succinct, and is stable, easy and simple to handle.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
Embodiment
(1) waste water is introduced into grid, and the grid inclination angle is 60 degree, and interval of grid strip is 15mm, and when waste water flow through, the bulk pollutent that is suspended state was held back by grizzly bar and removed from waste water, and grid can reduce the suspended substance protection subsequent disposal facility in the sewage;
(2) water outlet enters equalizing tank, makes water quality and the water yield keep relative stable, guarantees that the subsequent disposal system is stable, with alkali the pH value of waste water is adjusted to 5-6, and temperature regulation is to 34-38 ℃;
(3) water outlet enters anaerobe filter bed reactor and carries out a biological disposal upon, temperature of reaction is controlled at 35-38 ℃, bio-filter bed reactor passes through mud section, packing section, three phase separation section successively by following water-in water inlet upper reaches, draw methane gas in the three phase separation section, the anaerobe bacterial classification that carries out cultivating in the biological treatment process at anaerobe filter bed reactor comprises: hydrolysis bacterium, acidifying bacterium, methanobacteria.
(4) water outlet enters settling tank, removes suspended substance, the water outlet qualified discharge.
Can reach the requirement of GB8978-1996 first discharge standard through the water outlet after the above-mentioned processing.
Claims (3)
1. the treatment process of a food wastewater may further comprise the steps:
(1) waste water is introduced into grid and removes suspended substance;
(2) water outlet enters equalizing tank, to waste water store, homogeneous and adjusting;
(3) water outlet enters anaerobe filter bed reactor and carries out a biological disposal upon, bio-filter bed reactor passes through mud section, packing section, three phase separation section successively by following water-in water inlet upper reaches, draw methane gas in the three phase separation section, the anaerobe bacterial classification that carries out cultivating in the biological treatment process at anaerobe filter bed reactor comprises: hydrolysis bacterium, acidifying bacterium, methanobacteria;
(4) water outlet enters settling tank, removes suspended substance, the water outlet qualified discharge.
2. the treatment process of a kind of food wastewater according to claim 1 is characterized in that: described grid inclination angle is 60 degree, and interval of grid strip is 15mm.
3. the treatment process of a kind of food wastewater according to claim 1 is characterized in that: described equalizing tank, with alkali the pH value of waste water is adjusted to 5-6, and temperature regulation is to 34-38 ℃.
