Abstract
The present invention discloses a sewage treatment method and a device thereof. Firstly, sewage is collected by a settling pond to remove thick granules and suspended substances; secondly, the sewage is put into a plug-flow bed which is filled with fillers, such as gravel, etc. and planted with aquatic hygromorphism plants to further reduce suspended substances in the sewage for reducing sewage COD; thirdly, the sewage is put into a downstream flow pond-an upstream flow pond, and artificial wet land is filled with fillers, such as the gravel, fine sand, etc. and is also planted with the aquatic hygromorphism plants for degrading the sewage COD, eliminating nitrogen and phosphorus and removing heavy metal, exogenous biologically active materials, algae toxin and other special pollutants; lastly, the sewage is put into a water quality decorating pond which is filled with superficial-layer fine sand and planted with submerged plants for decorating treated water to finally drain water not reaching drain-in requirements or recycle. The method of the present invention has the advantages of easy realization, simple and convenient operation, low engineering cost and operation cost, good purifying effect and prompted water recycle.
Description
Technical field
The present invention relates to field of environment engineering, the device that more specifically relates to a kind of method of sewage disposal and realize this method.
Background technology
The ordinary method of urban sewage purification is a secondary biochemical treatment, after physical treatments such as precipitation, enters the aeration tank, handles through active sludge biological, discharges behind the redeposition.This treatment effect is fine, in the water aerobic substance particularly biochemical oxygen demand reduce significantly, but build, move, keep three the expense too high.Need to build facilities such as pond, pipe network, pumping plant, be used to during operation to promote with the power load of aeration etc. bigger, the sludge treatment complexity, the maintenance of certain hour domestic demand, maintenance, standing charges are higher, and the prerequisite of its operation must have perfect sewage collecting pipe network.By contrast, development " three is low " sewage disposal technology that initial cost is low, running cost is low and maintenance technology is low is good the replenishing that big city sewage is focused on, and is particluarly suitable for the perfect inadequately middle samll cities and towns of sewage network and uses.Europe and North America etc. utilize the wet land sewage purification function, the effect of comprehensive plant, microorganism and medium is disposed of sewage, this method has construction, running cost is low, advantages such as simple and convenient management, but be only limited to the reed bed system of single flat flow or upright streaming, it denitrogenates the poor effect of dephosphorization, and hydraulic load and pollution load are lower.
Summary of the invention
The purpose of this invention is to provide a kind of sewage water treatment method, easy to implement the method, easy and simple to handle, can impel the water reuse; Realize the ground water correction, protection drinking water source water body; Solving the problem that the medium and small town sewage of dispersive is handled, also is good the replenishing that big city sewage is focused on.
Another object of the present invention provides the device of this sewage water treatment method.
In order to achieve the above object, the present invention adopts following technical measures: adopt the bioprocess technology treatment technology, main processing unit is a vertical current constructed wetland, and its sum of series scale is decided on water quality; Looking the sewage quality situation before vertical current constructed wetland establishes the settling tank pre-treatment or adds the pulling flow type gravel bed system; After vertical current constructed wetland, look water quality and establish the modification pool or in line.Realize water correction and reuse.This method comprises the following steps: in order successively
(1) sewage is removed thick particle, suspended substance through settling tank;
(2) enter the plug-flow bed, reduce suspended substance in the sewage, prevent alluvial; Reduce COD of sewage, alleviate subsequent disposal unit pollution load;
(3) enter down flow artificial wet field, sewage is from the downward water distribution of the water distributor that is distributed in the whole surface of down flow artificial wet field, sewage evenly flows downward in the pond, collect water outlet with the collection tube that is distributed in the whole bottom surface of down flow artificial wet field, COD in the degradation water, denitrogenate dephosphorization, and remove specific pollutants such as heavy metal, exogenous bioactive substance, algae toxin;
(4) enter the up stream artificial swamp, sewage is from being distributed in the water distributor water distribution of the whole bottom surface of up stream artificial swamp, sewage evenly upwards flows in the pond, collects water outlet, the water pollutant of further degrading with the collection tube that is distributed in the whole surface of up stream artificial swamp;
(5) enter water quality and modify the pool, water outlet is modified;
(6) water outlet discharging or reuse.
Wherein the current in plug-flow bed, downstream and the up stream artificial swamp are undercurrent, and intaking is intermittent mode.
Be used to realize that the device of method of the present invention comprises:
A settling tank;
A plug-flow pond, in the plug-flow pond, be filled with gravel or rubble, on coarse gravel or rubble, implant aquatic, hygrophyte, on the coarse gravel of plug-flow pond one end or rubble, lay the water distributor water inlet of plug-flow pond, thrust water distribution by water, coarse gravel or rubble bottom laying plug-flow pond collection tube at the plug-flow pond the other end catchment, and go up ejectment then and go out;
A downstream pond, being filled with gravel or rubble at the bottom of the downstream pond, up is fine sand or rubble, implants aquatic, hygrophyte on fine sand or rubble, there is downstream pond water distributor on whole surface on the fine sand rubble in downstream pond, and the one deck in bottom, downstream pond is " H " collection tube with holes;
A up stream pond, filling out coarse gravel or rubble at the bottom of the up stream pond, up is fine sand or rubble, implants aquatic, hygrophyte on fine sand or rubble, one deck of bottom, up stream pond is a up stream pond water distributor, on the fine sand or the whole surface on the rubble in up stream pond up stream pond collection tube is arranged;
A water quality is modified the pool, and water quality is modified bottom, the pool and inserted the shallow-layer fine sand, implants submerged plant on the shallow-layer fine sand.
The present invention compared with prior art, have the following advantages and effect: good purification, the advanced treatment that can be used for sewage, exogenous organic matter, oestrogenic hormon, hereditary poisonous substance and specific pollutants such as algae toxin, heavy metal there is removal effect preferably, realize water correction and reuse, impel degeneration water ecosystem to recover, protection drinking water source water body; Construction costs is low, is the 1/3-2/3 of conventional secondary water processing establishment construction investment; Working cost is low, is the 1/5-1/2 of conventional secondary water processing establishment construction investment or lower; Have higher pollution load and hydraulic load ability, and be easy to regulate and control, easy and simple to handle, easy construction has the effect of beautifying view, preserves the ecological environment.
