Description
Technical field
The utility model is a kind of cell apparatus, is specially a kind of enzyme fuel cell unit based on water treatment.
Background technology
Since the Industrial Revolution, water treatment problems is perplexing developed country and developing country always.The energy consumption of sewage disposal is big, the operational and administrative expenses height, although thereby its social benefit and obvious environment benefit, economic benefit and not obvious, be one have high input, industry that output is few.Contain multiple organic substance in the waste water, how to utilize these biomass energies to obtain the generally attention of various countries.How to find a kind of can purifying water body, can be subjected to paying close attention to widely by energy-producing novel sewage water treatment method again.Increasing that government drops into and standard is carried out resource utilization to waste water when investing and utilized, can be in the working cost of balance sewage work to a certain degree.
Chang Yong wastewater processing technology mainly contained physics method, chemical method, biological process and electro-chemical water processing in the past, and wherein, physics method, chemical method cause secondary pollution easily; The ultimate principle that electro-chemical water is handled is to make pollutent that Direct Electrochemistry reaction or indirect electrochemical conversion take place on electrode.Be meant under the effect of extra electric field, in specific electrochemical reactor, chemical reaction, electrochemical process or physical process by a series of designs, produce a large amount of free radicals, and then the strong oxidizing property of utilizing free radical technical process that pollutants in waste water is degraded, be a kind of of high-level oxidation technology.But having a shortcoming to handle exactly, it needs extra electric field, consumed energy.Biological process with its economy and high processing efficient become present use widely, the method that can make final inorganicization of pollutent, mineralize, but it can only handle biocompatible organism effectively.
The utility model content
The purpose of this utility model has been to overcome the above-mentioned defective of existing method of wastewater treatment, a kind of continous way water treatment enzyme fuel cell unit that provides a kind of vortex generator that is made of upflowing rectangular reactor and four glass carbon plates to form.This device has characteristics such as treatment capacity is big, efficient is high, energy consumption is low.
To achieve these goals, the utility model has been taked following technical scheme.This device comprise reactor cap, with reactor cap surround an enclosed space housing, be arranged on the vortex generator in this enclosed space, the inhalent siphon that is connected with the enclosed space bottom, the rising pipe, the anode that are connected with enclosed space top draw lead and negative electrode is drawn lead.Wherein, Described housing comprises the shell that has through hole on inner casing, the proton exchange membrane that has through hole on the sidewall, the carbon paper negative electrode that is loaded with oxygen reduction catalyst and the sidewall from inside to outside successively, through hole on the shell is corresponding with the lead to the hole site on the inner casing, and the carbon paper negative electrode is drawn lead with negative electrode and is connected.Described vortex generator is surrounded by four glass-carbon electrode plates that are loaded with enzyme, and the glass-carbon electrode plate is provided with through hole, and anode is drawn lead and is connected with the glass-carbon electrode plate.
The internal diameter of the through hole on the described glass-carbon electrode plate is 2～4mm, and pitch of holes is 4mm.
The internal diameter of the through hole on the described inner casing is 8～10mm, and pitch of holes is 2～4mm.
The internal diameter of the through hole on the described shell is 8～10mm, and pitch of holes is 2～4mm.
Described inner casing, proton exchange membrane, carbon paper negative electrode and shell are bolted to connection.
Waste water flows into from the inhalent siphon of Vortex reactor bottom, flows out from the top rising pipe behind the vortex generator that scribbles enzyme of flowing through.In general, because fluid velocity can produce a gradient, and the flow velocity that is directly attaching inner-walls of duct is close to zero, and forms very thin aspect, this aspect was called as " diffusion boundary layer " in hydro science when current passed through straight pipeline.Contact with being loaded with oxidasic glass-carbon electrode for the thorough mixing of realizing water reaches, must remove this limiting layer.The introducing of vortex generator successfully is converted into eddy current with laminar flow, and the contact surface of water and electrode has been expanded greatly.
The utility model is compared with the traditional water treatment unit, and under the situation that reaches identical water treatment effect, because equipment while electrogenesis, energy consumption obviously reduces, and can save investment.Updraft structure can reduce floor space, reduces working cost.Operate continuously makes organism can fully contact the glass-carbon electrode that is loaded with enzyme, and treatment effect is more superior than static treatment, and providing to practical application may.Enzyme fuel cell utilizes enzyme as catalyzer, in the organic substance chemical energy of fuel is converted into electric energy in degrading waste water, has the function of waste treatment and Energy production concurrently, is a kind of novel water treatment method, has very big application potential.This method can reduce cost of sewage disposal greatly, and for vast with serious pollution developing country, this can realize cleaning production capacity and remove useless dual-purpose technology particularly practical simultaneously.
