Abstract

The utility model discloses a printing and dyeing wastewater treatment constructed wetland. The constructed wetland comprises a reaction tank (2) and a water outlet pipe (9), wherein the water outlet pipe (9) is arranged on the bottom of the reaction tank (2); a gravel packing layer II (7) of 8-16mm, a gravel packing layer (6) of 4-8mm, a mud-free coarse sand packing layer (5) of 0.2-6mm, a gravel packing layer I (4) of 8-16mm and a water inlet pipe (1) are sequentially arranged on the upper layer of the water outlet pipe (9). The constructed wetland is characterized in that a polyethylene (PE) membrane double-sided geotechnical cloth (15) is arranged on the bottommost part of the reaction tank (2), and an aquatic plant I (11), an aquatic plant II (12), an aquatic plant III (13) and an aquatic plant IV (14) are sequentially planted from the left to the right of the reaction tank (2). The constructed wetland for treating printing and dyeing wastewater is low in cost and has a quick effect; and the treated wastewater is better than the standard A of the first class in Discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002).

Description

A kind for the treatment of of dyeing and printing artificial swamp

Technical field

The utility model relates to the artificial swamp technical field, relates in particular to a kind for the treatment of of dyeing and printing artificial swamp.

Background technology

Artificial swamp be by artificial construction and control operation with the similar ground of swampland, sewage, mud there be batching on the artificial wetland of building of control, sewage and mud are in process of flowing in a certain direction, mainly utilize physics, chemistry, the biological triple synergies of soil, artificial dielectric, plant, microorganism, a kind of technology that sewage, mud are handled.Its mechanism of action comprises that absorption, delay, filtration, redox, precipitation, microbiological degradation, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of animals.

At present from having sewage disposal device now to the treatment of dyeing and printing weak effect, nitrogen in the dyeing waste water, phosphorus concentration is on the low side, color is mainly black, blueness or brown, having characteristics such as organic concentration height, colourity are big, difficult degradation, is to be badly in need of the technical problem that solves at present to handling such waste water therefore.

Summary of the invention

The purpose of this utility model is to overcome the problems referred to above, and a kind for the treatment of of dyeing and printing artificial swamp is provided.

Problem to be solved in the utility model is: at nitrogen in the present dyeing waste water, phosphorus concentration is on the low side, have that organic concentration height, colourity are big, the problem of difficult degradation, provide a kind of efficient, environmental protection, method of wastewater treatment cheaply.

For realizing the purpose of this utility model, the technical solution adopted in the utility model is:

A kind for the treatment of of dyeing and printing artificial swamp, comprise reaction tank, rising pipe, described rising pipe is arranged on the reaction tank bottom, described rising pipe upper strata is disposed with the gravel filling layer two of 8～16mm, the gravel filling layer of 4～8mm, 0.2 the no mud coarse sand packing layer of～6mm, gravel filling layer one and the water inlet pipe of 8～16mm, described water inlet pipe bottom is provided with several spout holes, be provided with several infiltration holes above the described rising pipe, it is characterized in that: described reaction tank bottommost is provided with the two-sided geotextile of PE film, and described reaction tank is from left to right planted successively and is implanted with waterplant one, waterplant two, waterplant three, waterplant four.

Preferably, the two-sided geotextile thickness of described PE film is 1mm.

Preferably, described waterplant one is reed.

Preferably, described waterplant two is Wildcelery Herb.

Preferably, described waterplant three is calamus.

Preferably, described waterplant four is Canna generalis Bailey.

The beneficial effects of the utility model are: by using this artificial swamp treatment of dyeing and printing, it is low to have a cost, instant effect.Waste water after handling all is better than " urban wastewater treatment firm pollutant emission standard " one-level A standard (GB18918-2002).

Description of drawings

Fig. 1 is front view of the present utility model;

Fig. 2 is vertical view of the present utility model;

Among the figure: 1, water inlet pipe, 2, reaction tank, 4, the gravel filling layer one of 8～16mm, 5, the no mud coarse sand packing layer of 0.2～6mm, 6, the gravel filling layer of 4～8mm, 7, the gravel filling layer two of 8～16mm, 8, infiltration hole, 9, rising pipe, 10, spout hole, 11, waterplant one, 12, waterplant two, 13, waterplant three, 14, waterplant four, 15, the two-sided geotextile of PE film.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

A kind for the treatment of of dyeing and printing artificial swamp, comprise reaction tank 2, rising pipe 9, described rising pipe 9 is arranged on reaction tank 2 bottoms, described rising pipe 9 upper stratas are disposed with the gravel filling layer 27 of 8～16mm, the gravel filling layer 6 of 4～8mm, 0.2 the no mud coarse sand packing layer 5 of～6mm, the gravel filling layer 1 of 8～16mm and water inlet pipe 1, described water inlet pipe 1 bottom is provided with several spout holes 10, be provided with several infiltration holes 8 above the described rising pipe 9, described reaction tank 2 bottommosts are provided with the two-sided geotextile 15 of PE film, and described reaction tank 2 is from left to right planted successively and is implanted with waterplant 1, waterplant 2 12, waterplant 3 13, waterplant 4 14, two-sided geotextile 15 thickness of described PE film are 1mm, described waterplant 1 is reed, described waterplant 2 12 is Wildcelery Herb, and described waterplant 3 13 is calamus, and described waterplant 4 14 is Canna generalis Bailey.

Principle of work of the present utility model is: waste water enters reaction tank 2 by the spout hole 10 of water inlet pipe 1 bottom, under the effect of gravity, waste water enters each packing layer successively and carries out filtration treatment, wherein the effect of the gravel filling layer 1 of 8～16mm in the reaction tank 2 is to prevent that no mud coarse sand packing layer 5 surfaces of the 0.2～6mm of its lower floor are by erosion attack, regular layout waterplant 1 successively, waterplant 2 12, waterplant 3 13, waterplant 14 can be improved COD in the waste water, ammonia nitrogen, the isocyatic treatment effect of TN and TP.Waste water is handled the back after filtration and is entered rising pipe 9 by infiltration hole 8 and discharge, and the two-sided geotextile of PE film of wetland bottom shop 1mm, can prevent effectively that waste water infiltration from arriving underground.
