Abstract

The present invention asks for protection a kind of intermission type artificial marsh sewage treating method and system, and system includes pond body, filler, water inlet pipe, rising pipe and vent-pipe etc.Filling matrix fill in the body of pond, and vent-pipe is set, plant plant on the filler.System comprises each cycle of operation: water inlet-reaction-water outlet and the emptying four-stage that leaves unused, sequence batch (operation, cycle recirculation.Water inlet pipe inserts from top, has strengthened the reoxygenation of system bottom in step of reaction by being provided with of vent-pipe, helps the raising of nitrated usefulness.After finishing, reaction discharges by the bottom rising pipe; Wetland enters the idle stage of emptying subsequently, and at the emptying lay-up period, wet land system is finished and strengthened the reoxygenation effect, has promoted the nitrated usefulness of system to improve, and has helped the oxygenolysis of mud, improves the obstruction of system.The present invention have treatment efficiency height, denitrification effect good, be difficult for stopping up, take up an area of less, advantage such as no energy consumption, investment and running cost are low.

Description

Intermission type artificial marsh sewage treating method and Sewage treatment systems
Technical field:
The invention belongs to sewage disposal, environmental protection technical field, be specifically related to a kind of wetland sewage disposal technology.
Background technology:
Do not see report at present both at home and abroad as yet relevant for the intermission type artificial marsh Sewage treatment systems.Existing artificial marsh sewage treating method mainly contains forms such as surface current, underground undercurrent and vertical current, is Continuous Flow; In practical engineering application, exist usefulness low, take up an area of big, particularly since in the system DO concentration low, make that nitrated usefulness is low and influence denitrification efficiency; And there are problems such as water distribution system complexity and water distribution be inhomogeneous.
Summary of the invention:
The present invention is directed to the deficiency that exists in the existing artificial swamp sewage disposal, a kind of intermission type artificial marsh sewage treating method and system have been proposed, improve treatment efficiency, reduce and take up an area of, solve the uniformity of water distribution problem, and can improve the silting problem of wet land system, the stability of wet land system is improved.
Technical scheme of the present invention is as follows:
Intermission type artificial marsh sewage treating method adopts the sequence batch (operation, and each cycle of operation comprises: water inlet-reaction-water outlet and the emptying four-stage that leaves unused, per stage according to the order of sequence batch mode move the cycle recirculation.Inlet and outlet water intermittently, the treating processes in each stage is as follows:
Water inlet: sewage is flow to the pond body through water inlet pipe from body top, pond;
Reaction: microorganism and the abundant contact reacts of plant in sewage and the pond body on the filler, simultaneously by air through the vent-pipe input, the reoxygenation of consolidation system bottom;
Water outlet: after reaction was finished, sewage was discharged by the rising pipe of pond body bottom;
Emptying is idle: make the system of emptying sewage enter the emptying lay-up period, rely on the reinforcement reoxygenation effect of the air of atmospheric natural reaeration and vent-pipe feeding, enter next loop cycle again.
The intermission type artificial marsh Sewage treatment systems that realizes aforesaid method comprises pond body, filler, vent-pipe, water inlet pipe and rising pipe etc.This system is made up of the pond body, in fill matrix fill, plant plant on the filler, water inlet pipe is arranged at body top, pond, and rising pipe is arranged at the bottom, is distributed with vent-pipe in the matrix fill of pond body, vent-pipe can be provided with many groups, every group is interconnected by ventilation standpipe and horizontal vent-pipe and to form, and the ventilation standpipe stretches out the water surface, and horizontal vent-pipe is distributed in the filler.
Above-mentioned intermission type artificial marsh sewage treating method and system compared with prior art have following characteristics:
1. strengthen the natural reaeration ability, system handles usefulness height, the denitrogenation ability is strong.
System adopts the sequence batch (operation, has strengthened the reoxygenation of system bottom by the setting (utilizing internal-external temperature difference) of vent-pipe in step of reaction; Simultaneously, at the emptying lay-up period, because the sewage emptying, the natural reaeration ability of system improves greatly, has improved the activity of nitrifier, helps the raising of system's denitrification efficiency.
2. improved the obstruction of system.
Emptying lay-up period in the intermission type artificial marsh Sewage treatment systems has made up sufficient aerobic environment to the microorganism on the filler, can promote the oxygenolysis of mud self, the obstruction of anti-locking system.
3. simplified water distribution system, water distribution is even.
Because periodic running is pressed by system, water intake mode is the Inlet and outlet water at intermittence, does not have the water distribution uniformity problem, need not to be provided with complicated water distribution pipe system, and water outlet is discharged from the wet land system bottom by rising pipe and gate valve, need not to be provided with the complicated water collection system that goes out.
4. take up an area of less, invest low, the convenient management of working cost.
The intermission type artificial marsh Sewage treatment systems has been strengthened the reoxygenation usefulness of system, and the treatment efficiency of system is improved greatly, and it is dark to increase the pond, helps reducing taking up an area of, and reduces construction investment; System does not have the energy consumption operation, and working cost is low; Convenient management.
Description of drawings
Fig. 1 is the structural representation of native system.
Embodiment:
Referring to Fig. 1, this treatment system includes pond body 2, filler 3, ventilation standpipe 4, horizontal vent-pipe 5, water inlet pipe 1 and rising pipe 6 and flowing water Valve 7 etc.Pond body 2 adopts the rectangle form pool body, fills filler 3 in the body of pond, establishes ventilation standpipe 4 and horizontal vent-pipe 5 in the filler 3, and ventilation standpipe 4 stretches out the water surface, and horizontal vent-pipe 5 is distributed in the filler.Body top, pond is connected water inlet pipe 1 and rising pipe 6 respectively with the bottom.Sewage enters the pond body by water inlet pipe 1, after microorganism on sewage and the filler and the plant 8 abundant contact reactss, opens the valve 7 on the rising pipe 6, and sewage is discharged by run by gravity.The wet land system of emptying sewage enters the emptying lay-up period, rely on the reinforcement reoxygenation effect of atmospheric natural reaeration and ventilation standpipe 4 and horizontal vent-pipe 5 after, enter next cycle circulation again.
Main technical details:
Flooding time: 1h;
Reaction times: 24~48h;
Emptying lay-up period: 6~12h;
The water outlet time: 1h;
Structural parameter:
Intermission type artificial marsh size: V=L * B * H;
Intermission type artificial marsh useful volume: V φ=HRT * Q (φ-matrix pores rate, Q-flow);
Matrix fill type: gravel etc.
