Abstract
一种曝气生物滤池，其特征是它包括集水槽（1）、陶粒滤料（2）、设备本体（3）、曝气主管（4）、曝气支管（5）、曝气进气口（8）、反冲洗进气口（9）、反冲洗进水口（10）和穿孔曝气管（11）。本曝气生物滤池下部或底部增加了曝气系统。根据水流方向其可分为上向流和下向流两种。由于下向流曝气生物滤池的纳污效率不高、易堵塞、运行周期短，因此现在多采用上向流方式(即采用气水同向流)，使布水、布气更加均匀。同时，在水气上升过程中可把底部截留的硫带入滤池中上部，增加了滤池的纳污能力，延长了工作周期。
A biological aerated filter, characterized in that it includes a sump (1), ceramsite filter material (2), equipment body (3), aeration main pipe (4), aeration branch pipe (5), aeration inlet Air port (8), backwash air inlet (9), backwash water inlet (10) and perforated aeration pipe (11). An aeration system is added to the lower part or bottom of the biological aerated filter. According to the direction of water flow, it can be divided into two types: upward flow and downward flow. Since the downflow biological aerated filter has low pollution-holding efficiency, is easy to block, and has a short operating cycle, the upflow method (that is, the air and water flow in the same direction) is now mostly used to make the water and air distribution more uniform. At the same time, during the rising process of water vapor, the sulfur trapped at the bottom can be brought into the middle and upper part of the filter, which increases the dirt-holding capacity of the filter and prolongs the working cycle.
Description
Technical field
The utility model relates to a kind of filter tank, especially a kind of BAF.
Background technology
At present, BAF (biological aerated filter) is compared with conventional activated sludge process, advantages such as having organic loading height, floor space little (be conventional activated sludge process 1/3), less investment (saving 30%), can not produce sludge bulking, oxygen transmission efficiency height, effluent quality are good, but it requires tight (general requirement SS≤100 mg/L to water inlet SS, best SS≤60mg/L), therefore need carry out pre-treatment to water inlet.Simultaneously, its back flushing water yield, head loss are all bigger.
The startup of BAF is identical with the Starting mode of general biomembrance process.Three kinds of modes of general abroad employing: 1. intermittently cultivating also progressively increases flow velocity; 2. under design current velocity or increase flow velocity gradually and carry out cultured continuously; 3. with active sludge inoculation, steady-state operation.Biomembranous growth velocity in three kinds of Starting mode, distribution and the Changing Patterns such as clearance of pollutent are had nothing in common with each other, but it is roughly the same to reach the required time of stable state.
Summary of the invention
The purpose of this utility model is to provide a kind of BAF, and this BAF adopts quick spoil disposal method, has biofilm characteristics rapidly.
The technical solution of the utility model is:
A kind of BAF, it comprises water leg, ceramic grain filter, apparatus body, the aeration person in charge, aeration arm, aeration inlet mouth, back flushing inlet mouth, back flushing water-in and boring aeration pipe, the middle part is provided with ceramic grain filter in the described apparatus body, the apparatus body top is provided with water leg, the aeration inlet mouth is arranged on the apparatus body, the aeration inlet mouth is positioned at ceramic grain filter, and ceramic grain filter connects aeration to be responsible for, and aeration is responsible for and is connected the aeration arm; Back flushing inlet mouth and back flushing water-in are arranged on the apparatus body, and the ceramic grain filter bottom is provided with the boring aeration pipe that is connected with the back flushing inlet mouth.
Described ceramic grain filter below is provided with filter plate, and filter plate is provided with the distribute water and air filter.
Described apparatus body is provided with water outlet, back flushing water port, arranges your drain and hand-hole.
The beneficial effects of the utility model are:
BAF of the present utility model bottom or bottom have increased aerating system.It can be divided into upward flow and following to two kinds of streams according to water (flow) direction.Since down to the stream BAF to receive not high, the easy obstruction of dirty efficient, the cycle of operation short, therefore now upward flow modes (promptly adopting the air water concurrent) that adopt make water distribution, gas distribution more even more.Simultaneously, in the aqueous vapor uphill process, can bring the sulphur that hold back the bottom into the filter tank middle and upper part, increase the water environment capacity in filter tank, prolong the work period.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Fig. 2 be among Fig. 1 A-A to sectional view.
Among the figure: 1 be water leg, 2 for ceramic grain filter, 3 for apparatus body, 4 for aeration be responsible for, 5 for the aeration arm, 6 for filter plate, 7 for the distribute water and air filter, 8 for the aeration inlet mouth, 9 for the back flushing inlet mouth, 10 for the back flushing water-in, 11 for boring aeration pipe, 12 for water outlet, 13 for the back flushing water port, 14 for your drain, 15 of row be hand-hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, Fig. 2, a kind of BAF, it comprises water leg 1, ceramic grain filter 2, apparatus body 3, the aeration person in charge 4, aeration arm 5, aeration inlet mouth 8, back flushing inlet mouth 9, back flushing water-in 10 and boring aeration pipe 11, the middle part is provided with ceramic grain filter 2 in the described apparatus body 3, apparatus body 3 tops are provided with water leg 1, aeration inlet mouth 8 is arranged on the apparatus body 3, aeration inlet mouth 8 is positioned at ceramic grain filter 2, ceramic grain filter 2 connects aeration and is responsible for 4, and aeration is responsible for 4 and is connected aeration arm 5; Back flushing inlet mouth 9 and back flushing water-in 10 are arranged on the apparatus body 3, and ceramic grain filter 2 bottoms are provided with the boring aeration pipe 11 that is connected with back flushing inlet mouth 9.
BAF of the present utility model can be finished functions such as carbonization, nitrated, denitrification, dephosphorization, can carry out the secondary or the tertiary treatment of general municipal effluent or trade effluent with other process combination.
The utility model has adopted quick spoil disposal method, and this method generally is to adopt the active sludge inoculation, discharges supernatant liquor after the vexed for some time of exposing to the sun of ventilate, adds treatment sewage again and continues vexed exposing to the sun for some time, intakes continuously then, air inlet is till steady-state operation.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
