Abstract
The utility model belongs to an aeration biological filter which utilizes biomembranes cultivated and naturalized by the dominant microorganism flora immobilized embedding technology to purify and treat raw water. A closed cell is arranged at the bottom of a filter body, the side of the cell is provided with a water inlet pipe, a back rinsing air pipe, and a back rinsing inlet pipe, a filter head is arranged at the upper end of the cell; the middle part of the filter body is provided with a biological filter material layer, an aeration device is arranged under the biological filter material layer and is communicated with an aerated pipe; and the upper part of the filter body is provided with a water outlet pipe and a back rinsing drain pipe. The utility model simplifies treatment equipment so as to reduce the occupation area of the equipment and the equipment investment, has good and stable effluent quality, high rinsing efficiency of the filter material layer, and stable operation, combines with the dominant microorganism flora immobilized embedding technology, and is suitable for treating high concentration ammonia nitrogen, difficult degradation and oligosaprobic waters.
Description
Technical field
The utility model belongs to a kind of device that utilizes apposition growth to carry out water treatment in the microorganism of the huge specific surface of filtrate, and particularly a kind of microbial film that utilizes the immobilization embedded technology of superior microorganism bacterial classification to cultivate, tame out carries out the BAF of purifying treatment to former water.
Background technology
The existing purification treatment technology that is used for micropollutant water, organic wastewater with difficult degradation thereby, exist the quite complicated defective of handling procedure, generally comprise treatment measures such as biological reaction tank, settling tank, materialization coagulation reaction tank, materialization settling tank, sand filtration or activated carbon filtration, even so, handle back effluent quality especially ammonia nitrogen, COD
Cr, total nitrogen still can not up to standard or stably reaching standard.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of BAF is provided, and in order to handle micro-polluted water or waste water, it has simplified treatment facility, both can reduce occupation area of equipment, can reduce facility investment again; Effluent quality is good, and stable; Filter material layer cleaning efficiency height, stable; In conjunction with the immobilization embedded technology of superior microorganism bacterial classification, be applicable to ammonia nitrogen in high density, difficult degradation and micropollutant water improvement.
The purpose of this utility model is achieved through the following technical solutions: a kind of BAF, it is characterized in that: it is made up of pond body, water inlet pipe, aerating system, aeration tube, backwash tube, filter material layer, cell, rising pipe, back flushing rising pipe and filter, the bottom of said pond body is provided with the cell of sealing, the side arrangement of cell has water inlet pipe, back flushing blast main, back flushing water inlet pipe, and filter is arranged in the upper end of cell; Body middle part, pond is provided with the biofilter material layer, and aerating apparatus is installed in the below of biofilter material layer, and aerating apparatus is communicated with aeration tube; Body top, pond is provided with rising pipe and back flushing water shoot.

Embodiment
Embodiment: as shown in Figure 1, a kind of BAF, utilize apposition growth to carry out water treatment in the microorganism of the huge specific surface of filtrate, this filter tank is made up of pond body 1, water inlet pipe 2, back flushing water inlet pipe 3, back flushing blast main 4, aerating system 5, aeration tube 6, rising pipe 7, back flushing rising pipe 8, filter material layer 9, cell 10 and filter 11, be provided with the cell of sealing in the bottom of pond body, the side arrangement of cell has water inlet pipe, back flushing blast main, back flushing water inlet pipe, and filter is arranged in the upper end of cell; Body middle part, pond is provided with the biofilter material layer, and aerating apparatus is installed in the below of biofilter material layer, and aerating apparatus is communicated with aeration tube; Body top, pond is provided with rising pipe and back flushing water shoot.
Principle of work: former water enters the airtight cell of body bottom, pond by water inlet pipe, enter body top, pond reaction zone through filter, liquid annularly flow from bottom to top in the body of pond, pass through filter material layer, the microorganism that has the filtrate apposition growth of huge specific surface area in the filter material layer with particular purification function, contact with organic pollutant and ammonia nitrogen in the water, hold back, mass transfer and biological metabolism DeR, water quality is purified, water after the purification is discharged from the overflow of body top, pond, the required oxygen of biodegradation process blasts air by aerating system by gas blower in the pond provide, microorganism metabolism increases unnecessary biology by regular gas, the pond body is discharged in the water recoil, and the device long-term stability is carried out.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
