Description
Technical field
The utility model relates to a kind of improvement of tower biological filter, is sewage disposal device, belongs to environment protection, the technical field of the biological treatment of sewage.
Background technology
Biological filter is the effect by the microbial film be attached on filling carrier, carries out biological degradation to containing organic sewage, and sewage is purified.
Traditional tower biological filter by tower body (comprising lattice canopy, tower body, access hole, ventilation hole) filtrate, water-distributing device (comprising water distributor, water inlet pipe) and water exhaust system (comprising water leg, water shoot) four parts.
Tower body is rounded or square, tower height 8-24 rice, diameter 0.5-3.5 rice, filtrate adopts plastics, glass reinforced plastic, the materials such as pottery make various forms of filler, and require that voidage is high, biology easily adheres to, filtrate steel grill support, floor height is less than 2.5 meters, leaves certain neutral gear, and every layer has access opening to change filtrate.
Traditional tower biological filter there is grid and filtrate easily blocks, ventilation effect is not good enough, oxidation efficiency is low, every layer has certain neutral gear, useful volume does not make full use of, and changes filtrate trouble, especially to the thiobacterium that some growth generation cycles are long, the breeding of nitrobacteria etc. is unstable, affects biophasic integrity.Because growth cycle is long, grid filtrate easily blocks, and needs to change filtrate, thiobacterium, and nitrobacteria just breeds, and forms microbial film, is destroyed, and therefore, to sulfur-bearing, water treatment effect that ammonium is higher is not good enough.
It is the sewage treatment process in recent years developed that BAF (BAF) is disposed of sewage, and has been popular, but studies less in China in American-European and Japan.The maximum feature of BAF integrates bio-oxidation and retains suspended solids, saves final settling tanks.In addition, this process volume load and hydraulic load large, floor space is little, less investment, oxidation efficiency is high, energy consumption working cost is low, effluent quality is good, the features such as sludge output is few, but in tradition (BAF) technology, because the filtering velocity adopted is lower, make the oxidation of pollutent and filter, 0.5 meter, end mainly concentrating on reactor, the capacity utilization in whole filter tank is low, due to gas in packing layer, liquid, Gu three-phase maldistribution, easily there is aeration channel short circuit phenomenon, reduce processing efficiency, its process range primary limitation is at city domestic sewage simultaneously, especially industrial sewage and high-concentration sewage are seldom related to.
Utility model content
For overcoming the defect that prior art exists, the utility model provides a kind of new tower biological filter, and large improvement has been carried out to traditional tower biological filter in described new tower biological filter, and one is cancel the steel grid supporting filtrate between layers.Two is replace filtrate with foam cement concrete brick, and build into cellular ventilating hole channel by laying bricks or stones by certain interval, three is be added with microorganism culturing agent and oxide catalyst in foam cement concrete brick.
Tower biological filter described in the utility model comprises tower basin body and tower basin lid, described tower basin body top is provided with sewage water inlet pipe, tower basin body bottom is provided with air inlet system and water exhaust system, described water exhaust system comprises water collecting basin, Graceful water pipe and effluent cycle pipe, lower end, tower filter tank is arranged in water collecting basin, described air inlet system comprises the blast inlet be disposed on tower basin body wall, sewage water inlet pipe bottom in tower basin body is provided with the water distributor of rotation, filtrate body is provided with below water distributor, described filtrate body is built by laying bricks or stones by the foam cement concrete brick interval of some layers setting interlaced with each other and is formed, cellular ventilating hole channel is formed between described foam cement concrete brick, containing microorganism culturing agent and oxide catalyst in described foam cement concrete brick.
Described microorganism culturing agent comprises magnesium hydroxide and ammonium sulfate, and described oxide catalyst comprises metallic iron, aluminium and copper.
Working mechanism of the present utility model utilizes the Cement Concrete brick foamed to be filtrate, and because Cement Concrete brick is in alkalescence, microorganism easily adheres to, and Cement Concrete brick space is high, and the ventilating hole channel of building formation by laying bricks or stones is conducive to natural ventilation, accelerates the oxide treatment of sewage.
Due to the cancellation of steel grid, filtrate foaming Cement Concrete brick and the cellular ventilating hole channel of building by laying bricks or stones by certain gap, avoid the obstruction of filtrate and grid, make it natural ventilation unimpeded, ventilation effect improves greatly, thus improves the oxidation efficiency to pollutent, because whole filtrate contains microorganism culturing agent and oxide catalyst, can turn out rapidly the superior microorganism phase this sewage being possessed to adaptability, especially to the thiobacterium that the growth generation cycle is long, nitrobacteria etc. are breeding rapidly.Maintain biophasic integrity, thus form the good bio-oxidation bed of exclusive performance, to degrade rapidly the organic pollutant of high stability difficult degradation, thus can high-concentration industrial sewage be processed, due to the cellular ventilating hole channel that filtrate is formed, avoid solid, liquid, gas three-phase maldistribution and cause aeration channel short circuit phenomenon, accelerates filtration oxidation rate, improves processing efficiency.
Tower biological filter described in the utility model is by the Cement Concrete brick of building foaming in tower body by laying bricks or stones, and containing multiple-microorganism nutrient chemical and oxide catalyst, by the cellular ventilating hole channel that certain interval is built by laying bricks or stones, the sewage water inlet pipe be provided with in tower connects water distributor, sewage enters biological filter by water distributor, the foam cement concrete brick supporting porous is provided with, grid, screen, water leg and water exhaust system at the bottom of tower.
The advantage that the utility model compared with prior art has: 1, because cellular ventilating hole channel makes that natural ventilation is unimpeded improves oxidation efficiency.2, because filtrate contains microorganism culturing agent and oxide catalyst, can breed rapidly the bio-oxidation bed forming exclusive performance good can process, and can process trade effluent, the organic pollutant of particularly can degrade high stability, difficult degradation.3, because being natural ventilation oxidation, filtrate cost and working cost low, 4, effluent quality is good.
