Abstract

The utility model relates to an artificial marsh plants bed used in the water system treatment in the rivers and lakes, the treatment of the life and industrial waste water or the treatment of the mud. The utility model includes a water prevention lining layer 1, turfs 2, plants 3, etc. The bottom of the device is provided with the water prevention lining layer 1, the upper surface of which is provided with the turfs 2 on which the plants are placed, wherein, the upper part of the water prevention lining layer 1 has a liquid inlet 5, and the bottom of the water prevention lining layer 1 has a waste water outlet 6. The device needs a small number of facilities and does not need the artificial aeration for oxygen supply, thereby the investment is just between one third and one fifth of the ordinary secondary treatment, and the occupation area is between one tenth and one fifteenth of the natural marsh. The device not only can eliminate the ordinary pollutants, but also remarkably eliminates the N and P pathogens. The device of the utility model can work in the whole year, without the flies, odors, noises and does not need the daily managers.

Description

The constructed wetland plant bed

Technical field

The utility model relates to a kind of materialization, biological sewage treatment technology, specifically, be that a kind of water system that is widely used in river, river, lake is administered and the constructed wetland plant bed of sewage disposal such as city municipal wastewater, sanitary sewage, trade effluent or sludge treatment.

Background technology

At present, wetland technology roughly is divided into 4 kinds, a kind of is natural wetland, promptly utilizes the quantities wet land treating system seldom of natural low-lying land or reed pond, adopts artificial embankment water conservancy diversion therebetween usually, the depth of water is generally at 30～60cm, its purification mechanism is similar to stabilizing sugar, but removes the ability raising of pollutent, the suitable advanced treatment of doing waste water; Another kind is the free-water level wetland, and promptly water distribution is earthward kept the certain thickness water layer, and current are pulling flow type and advance, and forms one deck insulated stream, and goes out stream from the face of land, and vertically there is the gradient in its plot, and the bottom is not sealed, not disturbance of original appearance, but the face of land should be manually smooth a little; It in the 3rd the groundwater flow wetland, it is the artificial reed bed of undercurrent type, the reed bed has soil and plant (reed, cattail etc.) medium to form, and there are water-resisting layer and the certain base slope of tool the bed end, and feed-water end is built a water distribution ditch along bedside and flowed out, built-in gravel, waste water is gone into edge of bed soil layer bottom undercurrent and is horizontal diafiltration from the cloth ditch, from the exhalent canal outflow of the other end, also establish the porous header in the gravel bed bottom, can connect with the rising pipe that can regulate an interior water level, with water level in the control bed; Also having a kind of is infiltration wetland, promptly takes the ground water distribution, and waste water imports catchment hidden pipe or collecting gutter outflow through horizontal diafiltration, and physics, chemistry and biological respinse by taking place in the face of land and the subsurface infiltration process are purified waste water.

Their shortcoming is: 1. floor space is big, is generally 2～3 times of traditional two stage biological facture of the processing power that communicates; 2. be not suitable for that the treating part is poisonous, harmful industrial waste water (as waste water such as chemical industry, plating, electronics); 3. system is subject to the influence of external environment, thereby has coarse operating parameter that relates to.

Technology contents

The purpose of this utility model is to provide a kind of floor space few, can effectively handle poisonous, harmful industrial waste water, and is easy to the constructed wetland plant bed of maintenance and management.

The utility model is achieved in that

Comprise waterproof lining 1, peat 2, plant 3, root system 4, fluid inlet 5, wastewater outlet 6, waterproof lining 1 is arranged at the bottom of this device, be equipped with peat 2 on the waterproof lining 1, plant 3 is arranged on the peat 2, root system 4 on the plant 3 places in the peat 2, on the top of waterproof lining 1 fluid inlet 5 is arranged, wastewater outlet 6 is arranged in the bottom of waterproof lining 1.

The utility model also adopts following technical scheme:

Waterproof lining 1 has the gradient.

Be furnished with water pipe in the waterproof lining 1.

The bed of waterproof lining 1 is dark to be 0.1～1.0M.

Advantage of the present utility model is: can directly use this device as the greening water source for the greenery patches, and need not to build large-scale trunk sewer and sewage work, also can be used as a kind of novel method that water saving, advanced treatment of wastewater and sludge drying are handled, because structures and equipment that this device needs are less, do not need artificial quick-fried gas oxygen supply, therefore investment is 1/3～1/5 of a general second-stage treatment technology, and its floor space is 1/10～1/15 of a natural wetland.This device not only can be removed conventional pollutent, simultaneously N, P pathogenic agent is also had tangible removal effect.Steady running does not throughout the year have mosquitos and flies to multiply, free from extraneous odour, and noiseless need not the daily administration personnel.

Description of drawings

Fig. 2 is a sectional view of the present utility model.

Concrete enforcement

As shown in Figure 1: waterproof lining 1 usefulness building stones are arranged, low on one side, on one side high, a gradient formed, the bed of waterproof lining 1 is dark can be between 0.1～1.0M, be equipped with peat 2 on the top of waterproof lining 1,3 kinds of plants are in peat 2, and the root system 4 on the plant 3 places in the peat 2, end top at waterproof lining 1 is provided with a fluid inlet 5, in order to adding leaching vat, be provided with wastewater outlet 6 at the other end of lining water repeatedly, the height of this outlet can be regulated.

As shown in Figure 2, in waterproof lining 1, be distributed with water pipe 7.
