Specific implementation mode
In order to preferably explain the present invention, in order to understand, below by specific embodiment, present invention work is retouched in detail
It states.
The present invention provides a kind of nitrogenous effluent treatment methods comprising following steps：
Biochemical unit is set, is provided with microbe stuffing in biochemical unit, activated sludge is added in biochemical unit, preferably
Ground first injects tap water in biochemical unit, makes to tame out for handling the micro- of nitrogenous effluent in the microbe stuffing of biochemical unit
Biological bacterium colony.For injection tap water and activated sludge is added without precedence requirement.It is of course also possible to first be added without originally
Water, but recycling microorganism bacterium colony when follow-up addition nitrogenous effluent, but domestication speed and domestication effect be not slightly good enough.
Preposition processing is carried out to nitrogenous effluent, which makes the content of the suspended solid in nitrogenous effluent specific
In value range, make the pH value of nitrogenous effluent in a specific range, and makes in nitrogenous effluent without causing pole to microbe colony
The substance of major injury prevents nitrogenous effluent from keeping microbe colony unbalance.
Preposition treated nitrogenous effluent is injected biochemical unit.
Nitrogenous effluent is handled in biochemical unit, at least partly microbe stuffing during nitrogenous effluent is processed
Vibration is generated by driving.When processing, it can be the water up to standard that marginal not enters that the output of nitrogenous effluent side is handled well, i.e., constantly have new
Nitrogenous effluent is injected, while also constantly having the water up to standard handled well to be discharged；Can also be to contain after injection nitrogenous effluent
Nitrogen waste water stops the regular hour in biochemical unit, the water one up to standard handled well in biochemical unit after a period of time
Play discharge.At least partly microbe stuffing generates vibration by driving, and it can be that whole microbe stuffings are all driven to refer to
Movable property life vibration can also be that a part of microbe stuffing generates vibration by driving, specifically will be explained below.
The water discharge after processing is up to standard.
Based on above-mentioned method and step, nitrogenous effluent treatment method provided by the present invention is handled to nitrogenous effluent
When, activated sludge makes attached microbial bacterium colony on microbe stuffing, microbe colony handle nitrogenous effluent；By using
The means of vibration make the surface boundary layer of the liquid level of water body disturb so that the oxygen in air is easier to dissolve in the table of water body
Face, and the region dissolved oxygen amount that the microbe stuffing of the underclad portion of water body is contacted with biochemical unit is smaller, makes shape in biochemical unit
At aerobic zone, anoxic zone and anaerobic zone, so that nitrogenous effluent is cleaned by the biochemical reaction in three regions, realizes to containing
The processing of nitrogen waste water；Vibration can to form microchannel in microbe stuffing so that microbe colony in microbe stuffing with
Preferably contact occurs for nitrogenous effluent, improves the treatment effeciency to nitrogenous effluent；Vibration can make the water body shape in biochemical unit
At disturbance, the mobility of water body is improved, prevents the appearance of flow dead zone；Due to being not necessarily to setting reflux, line clogging is not had
It happens；Dissolved oxygen amount is improved by way of vibration without setting aerator, meanwhile, compared to aerator, vibration
Energy consumption needed for device is smaller, more energy efficient；Through experiment, in the processing method, it can also stablize fortune without putting into the carbon source system
Row, operating cost are relatively low.
Preferably, the suspended solids content in nitrogenous effluent is made to be not more than 800mg/L in preposition processing, pH value is
5.5-9.5.Adjusting suspended solids content can be handled by putting into the modes such as flocculant or air supporting, and adjusting pH value can lead to
Addition acid-base reagent is crossed to be handled, nitrogenous effluent is processed to meet above-mentioned requirements after, then be input in biochemical unit.Into one
Step preferably pH value is 7.
Preferably, before injecting nitrogenous effluent to biochemical unit, tap water is injected to biochemical unit, Portugal is added in tap water
Grape sugar or sodium acetate；Above-mentioned substance, which is added, can improve the domestication speed of initial stage microbe colony.
Preferably, before injecting nitrogenous effluent to biochemical unit, anaerobic ammonia oxidizing bacteria is added into activated sludge；Addition is detested
Anaerobic ammonium oxidation bacterium can reduce the acclimation period of microbe colony, improve the denitrification ability of biochemical unit.
Preferably, when nitrogenous effluent is handled in biochemical unit, part microbe stuffing is fixed in biochemical unit,
Part microbe stuffing is vibrated by driving.During biochemical unit handles nitrogenous effluent, in fixed microbe stuffing
With by driving vibration microbe stuffing between nitrogenous effluent can be promoted to circulate, so that nitrogenous effluent is more fully located
Reason.
Preferably, the resonant frequency for detecting microbe stuffing makes microbe stuffing be vibrated under its resonant frequency.It can be with
Vibrating data collection device is set in biochemical unit, acquires and calculate the resonant frequency of microbe stuffing, control driving vibration
Vibrating device vibration frequency, the vibration frequency for making vibrating device is consistent with the resonant frequency of microbe stuffing, generate altogether
The consumption of energy can be reduced after shaking.Meanwhile the microorganism for being attached with microbe colony is collected during follow-up operation
After the real-time vibration frequency of filler, the microorganism in current microbe stuffing can be obtained by the real-time vibration frequency conversion
The quantity situation of bacterium colony.
Certainly, the vibration frequency of vibrating device is also not necessarily required to as the resonant frequency of microbe stuffing.According to not
Same situation can adjust the disturbance width of the surface boundary layer of the liquid level of water body by changing the vibration frequency of vibrating device
Degree, to adjust the dissolved oxygen amount of water body.Preferably, vibration is it is required that the upper end dissolved oxygen of biochemical unit reaches 2-5mg/L.
Preferably, include ferrous metals or magnetisable material at least partly microbe stuffing, to where microbe stuffing
Region apply variable magnetic field, make ferrous metals or magnetisable material that at least partly microbe stuffing be driven to vibrate.By additional
Variable magnetic field makes the microbe stuffing vibrate.
Preferably, multiple biochemical units vertically arranged are set, convenient in the biochemical unit of upper layer
Water body, which can drop, to be flowed in the biochemical unit of lower layer, and water body is contacted with oxygen to increase in water body during dropping stream
Dissolved oxygen amount.In the preferred scheme, the multiple biochemical units vertically arranged are set, evolution can be formed from top to down
Formula microbe colony, each section can be achieved different purification functions, and whole system has better stability and impact resistance, together
When, during stream drops in water body from top to bottom, in conjunction with the effect of vibration, more oxygen can be allowed to dissolve in water body, to height
The nitrogenous effluent of COD has better treatment effect.
Further preferably, lifting device is set, and lifting device carries the water body in the biochemical unit of lower layer
It is raised in the biochemical unit of upper layer.The drop flowing water body of biochemical unit positioned at lower layer is promoted again on relatively
In the biochemical unit of layer, better treatment effect is had for the nitrogenous effluent of high nitrogen concentration or high chemical oxygen demand.
In the absence of conflict, the feature in the above embodiments and embodiment can be combined with each other.
It is to be appreciated that describing the skill simply to illustrate that the present invention to what specific embodiments of the present invention carried out above
Art route and feature, its object is to allow those skilled in the art to can understand the content of the present invention and implement it accordingly, but
