Background technology
Anaerobic hydrolysis-acidification and reduction by catalytic iron all are a kind of effective indegradable industrial effluent pretreatment processs, after acidication or reduction by catalytic iron pre-treatment, can improve the biodegradable property of wastewater energy, improve the effect of subsequent biological treatment.But when using this waste water of acidication pre-treatment separately, very poor to the removal effect of toxic pollutants, and continous-stable operation for a long time; And when using the reduction by catalytic iron pre-treatment separately, the removal of macromole straight chain aliphatic hydrocarbon and heterocyclic aromatic compounds almost not being had effect, the biodegradable performance of waste water improves limited.Chinese patent " a kind of sewage disposal blocking filler or filtrate device " (200520045030.0) is to disclose a kind of blocking filler or filtrate device that is used for sewage disposal, adopts the blocking filtrate frame of upward flow, and tracheae is housed, and can carry out back flushing.But this device can only be selected the upward flow mode for use only in bottom opening, and energy consumption is higher, and is not suitable for the flat flow reactor for hydrolysis and acidification.Chinese patent " anaerobic biological reactor that uses in the wastewater treatment equipment " (01822157.2) relates to comprise the wastewater treatment equipment that needs microorganism and upflow type anaerobic reactor, is a kind of anaerobic biological reactor that adopts upward flow equally.Chinese patent " reactor for hydrolysis and acidification " (200620074940.6) is to disclose a kind of reactor for hydrolysis and acidification, its principal character is that inside is provided with umbrella shape stirring disk, and below establish constant-current stabilizer, play the effect of reinforcing mass transfer, and use constant-current stabilizer on top, realize that muddy water separates voluntarily.Prior art is difficult to satisfy the processing requirements of complicated condition of water quality about the device that the exploitation and the patent of this aspect mainly is aimed at single acidication or reduction by catalytic iron processing aspect.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of can be with reduction by catalytic iron device and acidication reaction combination, good sewage processing effect, energy consumption is little, efficient is high flat flow acidication and catalysis iron coupled reactor.
Solution of the present utility model is: a kind of flat flow acidication and catalysis iron coupled reactor, the acidication reaction tank that comprises a flat flow, the acidication reaction tank has water-in and water outlet, have the reciprocal gallery of multistage between described water-in and the water outlet, be mounted with catalysis iron filtrate at least one section gallery therein.
The framework that described catalysis iron filtrate places PVC plastic plate or glass reinforced plastic anticorrosive to make, the catalysis iron filtrate of formation frame-type.
The utility model has the advantages that:
(1) owing in reactor for hydrolysis and acidification, be provided with catalysis iron packing area,, improves the pretreating effect of used water difficult to degradate so can bring into play the synergy of acidication and reduction by catalytic iron;
(2) catalysis iron is blocking filtrate device, is convenient to filling and replacing, and in the rear and front end perforate, can moves by the advection mode;
(3) the acidication reaction tank can be designed as many gallerys formula, increase sewage and catalysis iron duration of contact and and prevent short flow phenomenon generation;
(4) acidication/catalysis iron coupled reactor is the flat flow reactor, can be than vertical-flow head loss, the reduction operation energy consumption of reducing;
(5) acidication/catalysis iron coupled reactor can advance the switching of water and water outlet automatically, realizes that pool inner water flows to backflow movingly, effectively reduces the mud loss, does not need to be provided with the internal reflux system and can guarantee sludge concentration;
(6) be added with catalysis iron filtrate in the novel reactor,, can effectively prevent the alluvial of mud, reduce the obstruction of catalysis iron filler, improve processing efficiency in catalysis iron packing area by the alternate run of forward and reverse stream.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in the figure, embodiment of the present utility model includes the acidication reaction tank 1 of a flat flow, the acidication reaction tank has water-in 2 and water outlet 3, has gallery 4 between water-in and the water outlet, is mounted with catalysis iron filtrate 5 in two sections gallerys of intermediary.Catalysis iron filtrate is made up of the structural arrangement of a plurality of blocking, the framework that filtrate places PVC plastic plate or glass reinforced plastic anticorrosive to make, and the left and right sides panel of framework needs perforate, guarantees permeablely, and percentage of open area is greater than 30%.The framework base plate also needs perforate permeable, is convenient to the desilting slag that falls, and percentage of open area is greater than 20%.
Among the embodiment shown in Figure 1, the acidication reaction tank is made up of four gallerys, and wherein whole reactor is long 12 meters, and is wide 10 meters, high 3 meters, 2 meters of available depths.Wherein the wide of I, IV gallery is respectively 2 meters, and the wide of II, III gallery is respectively 3 meters.At two gallerys of intermediary catalysis iron packing area is set, each packing area is rearranged by 6 blocking catalysis iron filtrates, divides two dischargings to put, and every discharging is put 3, each blocking filtrate framework is of a size of 1.5 * 1.5 * 2 meters, and the tap density of catalysis iron filtrate is 0.2t/m
3And the cumulative volume of catalysis iron filtrate is 54m
3, total effective volume of whole reactor for hydrolysis and acidification is 240m
3, promptly catalysis iron packing volume accounts for 22.5% of whole reactor effective volume.
Waste water at first enters gallery I by water-in, is flowed out by water outlet behind flow through successively then gallery II, III, the IV, and waste water contacts with catalysis iron filler respectively in gallery II, III chemical reaction takes place.Switch behind the operation some cycles (24h), waste water is at first entered by the other end water-in, is flowed out by the other end water outlet behind flow through successively then IV, III, II, the I gallery.Switch automatic successively alternate run behind the operation some cycles once more.
