Abstract
The biochemical sewage treating apparatus has inside structure comprising four parts of soft stuffing, aerator, biological culture device and water inlet and outlet. By means of special method, the present invention forms aerobic area, facultative area and anaerobic area simultaneously inside one pond, so as to raise the treating efficiency on organic pollutant and ammonia nitrogen and reduce produced sludge. The present invention has the features of simple structure, unattended operation, small covered area, low cost, etc. and is suitable for two stage treatment of industrial waste water and domestic sewage.
Description
The present invention relates to a kind of sewage treatment structure, belong to a kind of sewage disposal device.
The aerobe treatment technology is often adopted in the sewage disposal of being rich in the solubility easily biodegradable organics.In the aerobe treatment technology, biological contact oxidation process is a kind of bio membrane process between activated sludge process and biological filter, finds broad application in recent years.
Traditional biological contact oxidation pond is made up of pond body, filler, water-distributing device and aerating system four parts.Generally, packed height is about 3.0 meters in the biological contact oxidation pond, and the water layer height is about 0.5 meter on the packing layer, and cloth pool height is between 0.5～1.5 under the packing layer; Aerating apparatus is located at the filler bottom, adopts blast aeration system, and gas-water ratio is 15: 1; Water-in is located at below the packing layer, the overflow water outlet.The characteristics of this structure are that biomass height, volumetric loading are big, treatment effect is good.But also exist the incubation time of natural microorganisms flora long simultaneously, bacterial classification will pass through the domestication process to the adaptive faculty of water quality; Sludge quantity is big, needs excess sludge is handled; Remove the ammonia nitrogen weak effect; Aeration intensity is big, shortcomings such as working cost height.
The objective of the invention is to research and develop that a kind of floor space is little, treatment effect good, energy consumption is low, convenient management, working cost be low, can handle various sewage, comprise the novel sewage treatment unit of industry sewage such as sanitary sewage, food brewery industry, Animal Product Processing Industry, processing of aquatic products industry, culture fishery.
Biochemical sewage treatment device of the present invention is to have done certain improvement on the basis of biological contact oxidation pond.It is characterized in that device is the rectangle pond body of the sealing of skeleton construction, establishes inspection port above.The pond significant depth is 2～5 meters, and Chi Tichang is 3～5: 1 with wide ratio, and the residence time in single pond is 3～6 hours; The water layer height is 0.5 meter on the packing layer, and cloth pool height is between 0.5～0.8 meter under the packing layer; Aerator is selected oversleeve formula aerator (Φ 60 * 600) or collar plate shape micro-hole aerator (Φ 250) for use, and the aerator spacing is 1 meter, is installed in filler bottom, and mounting height is at the bottom of the pond 0.5 meter usually, adopts blast aeration system, and gas-water ratio is 10: 1; Containers for culturing organisms is placed at the bottom of the pond, and thickness is 0.1～0.3 meter; Entery and delivery port becomes diagonal lines to arrange.
The new technology that the present invention adopts comprises: 1. containers for culturing organisms.It is by the wooden device through special processing, remove and easily cause putrid composition, preserve compositions such as wherein a certain amount of Mierocrystalline cellulose, xylogen, handle through physical method, make it reach the porosity that is fit to microorganism growth required 75%～85%, with the appropriate carrier as microorganism, it is to be produced by Taiwan Jin Yuan biotechnology company; 2. biological liquid agent.It is to belong to more than 80 kind of effective microbe by more than 10 to cultivate the novel microorganism mixture that forms, and also is to be produced by Taiwan Jin Yuan biotechnology company; 3. micro-hole aerator.Not only tiny intensive, the good charging of bubble that aerator produces, and can cover automatically when stopping air feed, prevent that pore from stopping up; 4. provide and be suitable for aerobic bacteria, double oxygen bacterium, anerobe survival environment.Because the special construction of pond body forms aerobic zone, aerobic area and anaerobic zone in the pond, when eliminating organic pollutant, finish the nitrification and denitrification reaction of biological denitrificaion.
Adopt effect of the present invention to be, simple in structure, easy construction, can imbed underground.The volumetric loading of disposing of sewage is 4～6kgBOD
5/ (m
3.d), the residence time is 3～6 hours, and BOD, COD, ammonia nitrogen removal frank are more than 90%.Compare with biological contact oxidation pond, the removal effect of ammonia nitrogen is obvious especially, identical volumetric loading, and aeration rate reduces 30%, can save facility investment, and working cost has bigger reduction.
Fig. 1 is the internal structure synoptic diagram of biochemical sewage treatment device of the present invention.An embodiment of invention is described below in conjunction with accompanying drawing.
Among Fig. 1, the 1st, pool wall, the 2nd, water-in, the 3rd, water outlet, the 4th, inspection port, the 5th, containers for culturing organisms, the 6th, aerator, the 7th, soft-filler.
Treatment sewage enters the pond from water-in 2, adds biological liquid agent (per 2～4m simultaneously in the pond
3The sewage add-on is 1L), be positioned at the microorganism species that yards up on the containers for culturing organisms 5 (want before adding to soak or drench with clear water earlier, take 10～15 days usually) at the bottom of the pond because anoxic and under the competent condition of carbon source realizes nitrated, the denitrification process of ammonia nitrogen; The microorganism species that yards up on the packing layer 7 carries out bio-contact oxidation under the condition of aerator 6 (gas-water ratio was controlled at 10: 1) oxygenation, sewage is through aerobic, hold concurrently oxygen, anaerobic process like this, finish organic degraded in the sewage, treating water is flowed out by rising pipe 3.
