Description
Technical field
The utility model relates to sewage treatment area, specifically be a kind of drowned flow artificial wet land sewage disposal reaction tank.
Background technology
The artificial swamp sewage disposal reaction tank be artificial build, the wet land system of controllable and through engineering approaches, its design and construction are to carry out sewage disposal by the optimum combination to the physics in the wetland natural ecosystems, chemistry and biological action.This sewage disposal technology no matter from its kind that can dispose of sewage, still can be removed the kind of pollutent from it, has practicality more widely than other sewage disposal technologies.As heavy metal wastewater thereby, contain multiple pollutent but sewage such as very low precipitation runoff water of concentration and percolate all are difficult to handle with active sludge or biomembrane process, but but can reach good effect with the artificial swamp sewage disposal reaction tank.
The artificial swamp sewage disposal reaction tank mainly is made up of impervious barrier and hypothallus, the main effect of impervious barrier is to stop sewage to underground and seepage on every side, hypothallus is the core that artificial swamp is disposed of sewage, and is mainly formed by fillings such as filler, waterplant, microorganisms.According to the difference of sewage water surface position in wetland, the artificial swamp sewage disposal reaction tank can be divided into surface low artificial swamp sewage disposal reaction tank and drowned flow artificial wet land sewage disposal reaction tank two classes.The sewage water surface of surface low artificial swamp sewage disposal reaction tank is positioned at more than the wet land filler, and its depth of water is generally 0.3～0.5 meter, and sewage slowly flows through the wetland surface from import, part of contaminated water evaporation or infiltration wetland, and water outlet is flowed out through overflow weir.The drowned flow artificial wet land sewage disposal reaction tank is that the sewage water surface is positioned at below the wet land filler, the drowned flow artificial wet land sewage disposal reaction tank is because it has made full use of the space of wetland, brought into play the synergy between system's (waterplant, microorganism and filler), therefore its sewage load is more much bigger than surface low artificial swamp sewage disposal reaction tank under the equal area situation.In addition, sewage flows at subsurface basically in the drowned flow artificial wet land sewage disposal reaction tank, high insulating effect, and treatment effect is subjected to the influence in weather, season less, sanitary condition is good, and therefore many both at home and abroad at present employing drowned flow artificial wet land sewage disposal reaction tanks are disposed of sewage.
But the drowned flow artificial wet land sewage disposal reaction tank is disposed of sewage and following problem often occurs in actual motion: because the action of gravity of current, the residence time of sewage in wet land filler is relatively limited, can't play abundant soil-removing action; Because be filled in the body of pond after the filler of variable grain size mixes, body space, pond is few and little, this makes and stops up easily when sewage by suspended thing or solid particulate matter are more, thereby causes sewage to overflow and pollute surrounding environment.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes above prior art problem, and a kind of drowned flow artificial wet land sewage disposal reaction tank is provided.This drowned flow artificial wet land sewage disposal reaction tank can prolong the residence time of sewage in wetland greatly, can effectively improve sewage treating efficiency, and is difficult for stopping up.
For solving the problems of the technologies described above, the utility model provides a kind of drowned flow artificial wet land sewage disposal reaction tank, described drowned flow artificial wet land sewage disposal reaction tank comprises pond body, matrix and water pipe, matrix comprises that survival has filler and the waterplant of microorganism, filler is filled in the body of pond, water plant planting is on filler, described pond body is separated into a plurality of reaction tanks, adjacent reaction is communicated with successively by water pipe between the pond, the water-in of each reaction tank and water outlet are positioned at the diagonal position of reaction tank, water-in is positioned at reaction tank top, and water outlet is positioned at the reaction tank bottom.
After adopting above structure, the utility model compared with prior art, have following remarkable advantage and beneficial effect: a pond body is separated into a plurality of reaction tanks, adjacent reaction is communicated with successively by water pipe between the pond, the water-in of reaction tank and water outlet are positioned at the diagonal position of reaction tank, sewage deflector type in reaction tank advances, this has effectively utilized the area of whole wetland, prolonged the residence time of sewage in wetland greatly, give waterplant, matrix such as microorganism and filler adequate time is handled sewage, and the setting of a plurality of reaction tanks has improved the sewage treatment capacity of wetland greatly, makes water outlet reach discharging standards; The water-in of reaction tank is positioned at reaction tank top, and water outlet is positioned at the reaction tank bottom, makes current comply with the flow of water and flows, and is difficult for stopping up, be unlikely to make sewage because of there not being the outlet spill-over, thus the pollution surrounding environment.
Described pond body is separated into four reaction tanks, is respectively first step reaction tank, second stage reaction tank, third stage reaction tank and fourth stage reaction tank, and four reaction tanks are arranged in turn.The reaction tank quantity of separating can not can not can not realize removing the purpose of pollutent too much very little very little effectively, too much need not, can cause waste.
The size of described filler in four reaction tanks reduces in turn.Packing material size is bigger in the first step reaction tank, mainly removes larger particles and partial organic substances, and the packing material size in each order reaction pond reduces gradually later on, and this has effectively prevented the blockage problem that wetland occurs easily in operational process.
Described water pipe comprises water inlet pipe, rising pipe, water distributor and header, and the water-in section of reaction tank adopts water distributor, and the water outlet section of reaction tank adopts header; Described water inlet pipe is communicated with the water distributor of first step reaction tank, and rising pipe is communicated with the header of fourth stage reaction tank, and header is communicated with the water distributor of next stage reaction tank.Be connected by water pipe between such four reaction tanks, sewage enters the artificial swamp sewage disposal reaction tank from water inlet pipe, in reaction tank, carry out absorption, absorption and the chemical reaction of pollutent after, discharge from rising pipe.
Described water inlet pipe is identical with water distributor height in the first step reaction tank, in water inlet pipe, the second stage reaction tank in water distributor, the third stage reaction tank in water distributor, the fourth stage reaction tank height of water distributor, rising pipe reduce in turn; The height unanimity of described header.Sewage enters from higher highly relatively water inlet pipe like this, discharges smoothly from highly relatively low rising pipe, complies with current trend, is difficult for refluxing, and is difficult for stopping up.
Described water inlet pipe and rising pipe are positioned at external top, pond.Sewage is complied with the flow of water in reaction tank like this, is difficult for stopping up.
Described a plurality of reaction tank is separated with dividing plate, and dividing plate is the PVC material.Use the dividing plate of PVC material to provide cost savings on the one hand, saved the space on the other hand, increased the wetland processing area indirectly.
