Description
Technical field
The present invention relates to a kind of improvement of tower biological filter, are sewage disposal device, belong to environmental protection, the biology of sewage
The technical field of processing.
Background technique
Biofilter is to carry out by the effect for the microbial film being attached on filling carrier to the sewage containing organic matter
Biodegrade makes to purify the sewage.
Traditional tower biological filter is by tower body（Including grid, tower body, access hole, ventilation hole）Filtrate, water-distributing device（Packet
Include water distributor, water inlet pipe）And drainage system（Including catch basin, drainpipe）Four parts.
Tower body is rounded or rectangular, and 8-24 meters of tower height, 0.5-3.5 meters of diameter, filtrate uses plastics, glass reinforced plastic, ceramics etc.
Various forms of fillers are made in material, it is desirable that voidage is high, and biology easily attachment, filtrate steel grill support, layer height is less than 2.5
Rice, there are certain neutral gear, every layer has manhole to replace filtrate.
There are grids and filtrate to be easy blocking for traditional tower biological filter, and ventilation effect is not good enough, and oxidation efficiency is low, and every layer
There is certain neutral gear, dischargeable capacity does not make full use of, replacement filtrate trouble, especially thin to the sulphur that some growth generation cycles are long
The breeding of bacterium, nitrobacteria etc. is unstable, influences the integrality of biofacies.Because growth cycle is long, grid filtrate easily blocks, and needs
Filtrate, sulfur bacteria are replaced, nitrobacteria just breeds, and forms biomembrane, is destroyed, therefore, to sulfur-bearing, the higher waste water of ammonium
Treatment effect is not good enough.
Biological aerated filter（BAF）Handling sewage is the sewage treatment process developed in recent years, is in American-European and Japan
Prevalence, but it is less in China's research.The feature of biological aerated filter maximum is to integrate biological oxidation and retention suspended solid,
Save final settling tanks.In addition, the process volume load and hydraulic loading are big, occupied area is small, small investment, and oxidation efficiency is high,
The features such as energy consumption operating cost is low, and effluent quality is good, and sludge output is few, but in tradition（BAF）In technology, because use filtering velocity compared with
It is low, so that the oxidation of pollutant and filtering are concentrated mainly at 0.5 meter of the end of reactor, the capacity utilization in entire filter tank
It is low, since gas, liquid, solid three-phase separate reduces treatment effeciency with aeration channel short circuit phenomenon unevenly, is easy to appear in packing layer,
Its process range primary limitation is especially seldom related to trade effluent and high-concentration sewage in city domestic sewage simultaneously.
Summary of the invention
To overcome defect of the existing technology, the present invention provides a kind of new tower biological filter, described new tower
Biofilter has carried out big improvement to traditional tower biological filter, first is that cancelling the steel lattice for supporting filtrate between layers
Grid.Second is that replacing filtrate with foamed cement concrete brick, build by certain interval at cellular ventilating hole channel, third is that foamed cement concrete
Microculture agent and oxidation catalyst are added in brick.
Tower biological filter of the present invention includes tower basin body and tower basin lid, and tower basin body top is provided with wastewater influent
Pipe, tower basin body lower part are provided with air inlet system and drainage system, and the drainage system includes collecting-tank, clear water outlet pipe and sewage
Circulation pipe, tower filter tank lower end are arranged in collecting-tank, and the air inlet system includes the air inlet being arranged at intervals on tower basin body wall,
The intracorporal sewage water inlet pipe lower part of tower basin is provided with the water distributor of rotation, filtrate body, the filter are provided with below water distributor
Material is built by the foamed cement concrete brick interval of several layers setting interlaced with each other, is formed between the foamed cement concrete brick
Cellular ventilating hole channel contains microculture agent and oxidation catalyst in the foamed cement concrete brick.
The microculture agent includes magnesium hydroxide and ammonium sulfate, and the oxidation catalyst includes metallic iron, aluminium and copper.
It is filtrate that working mechanism of the invention, which is using the Cement Concrete brick of foaming, and because Cement Concrete brick is in alkalinity, microorganism is easy
Attachment, Cement Concrete brick gap is high, and the ventilating hole channel for building formation is conducive to gravity-flow ventilation, accelerates the oxidation processes of sewage.
Due to the cancellation of steel grid, the Cement Concrete brick of filtrate foaming and the honeycomb ventilation built by certain gap
Duct avoids the obstruction of filtrate and grid, is allowed to that gravity-flow ventilation is unimpeded, and ventilation effect greatly improves, to improve to pollution
The oxidation efficiency of object can turn out rapidly and have to the sewage since entire filtrate contains microculture agent and oxidation catalyst
The superior microorganism phase of standby adaptability, sulfur bacteria especially long to the growth generation cycle, nitrobacteria etc. breed rapidly.Dimension
The integrality of biofacies is protected, to form the good biological oxidation bed of exclusive performance, the high stability that can degrade rapidly is difficult to degrade
Organic pollutant, due to the honeycomb ventilating hole channel that filtrate is formed, avoids solid, liquid so as to handle high-concentration industrial sewage,
Gas three-phase separate causes aeration channel short circuit phenomenon with uneven, accelerates filtering oxidation rate, improves treatment effeciency.
Tower biological filter of the present invention is the Cement Concrete brick by building foaming in tower body, and contains multiple-microorganism
Nutrient chemical and oxidation catalyst, by the honeycomb ventilating hole channel that certain interval is built, the sewage water inlet pipe being equipped in tower connects cloth
Hydrophone, sewage enter biofilter by water distributor, and tower bottom is provided with the porous foamed cement concrete brick of support, and grid, catchments at screen
Slot and drainage system.
The present invention has the advantage that compared with prior art：1, since honeycomb ventilating hole channel makes the unimpeded raising of gravity-flow ventilation
Oxidation efficiency.2, since filtrate contains microculture agent and oxidation catalyst, it can breed that form exclusive performance good rapidly
Biological oxidation bed can be handled, and can handle industrial wastewater, and can especially degrade high stability, organic pollutant difficult to degrade.3, because
Be gravity-flow ventilation oxidation, filtrate cost and operating cost are low, 4, effluent quality it is good.
