Abstract
The utility model provides a batch-type artificial swamp sewage treatment reactor. The reactor comprises a pond body, a stuffing, a water inlet pipe, a water outlet pipe, and a ventilating pipe. The pond body is filled with the substrate stuffing and provided with a ventilating pipe, and plants are planted on the stuffing. Each operation cycle of the reactor comprises a water inlet, reaction, water outlet and exhaust-idle four stages, the reactor operates in batch type, and the period is repeatedly cycled. The water inlet pipe is introduced from the upper part, and the reaeration at the bottom of the system is reinforced by disposing the ventilating pipe at reaction stage, so as to be in favor of the improvement of the nitrification efficiency. The sewage is exhausted by the water outlet pipe at the bottom after reaction, and then the swamp sewage is introduced into exhaust-idle stage, during which the reactor performs reinforced reaeration, so as to promote the improvement of nitrification efficiency, be in favor of the oxidative decomposition of sludge, and improve the clogging phenomenon of the reactor. The utility model has the advantages of high treatment efficiency, good denitrification effect, clogging resistance, small land area, no energy consumption, and low investment and operating cost.
Description
Technical field:
The utility model belongs to sewage disposal, environmental protection technical field, is 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 utility model is at the deficiency that exists in the existing artificial swamp sewage disposal, a kind of intermission type artificial marsh sewage-treating reactor has 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.
The technical solution of the utility model is as follows:
The intermission type artificial marsh sewage-treating reactor comprises pond body, filler, vent-pipe, water inlet pipe and rising pipe etc.Fill matrix fill in the body of pond, plant plant on the filler, water inlet pipe is arranged at body top, pond, rising pipe is arranged at the bottom, be distributed with vent-pipe in the matrix fill of pond body, vent-pipe can be provided with many groups, and every group is interconnected by ventilation standpipe and horizontal vent-pipe and to form, the ventilation standpipe stretches out the water surface, and horizontal vent-pipe is distributed in the filler.
This reactor 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 that atmospheric natural reaeration and vent-pipe feed to recover microbic activity after, enter the next cycle circulation again.
Above-mentioned intermission type artificial marsh sewage-treating reactor compared with prior art has following characteristics:
1. strengthen the natural reaeration ability, reactor for treatment usefulness height, the denitrogenation ability is strong.
Reactor 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 reactor improves greatly, has improved the activity of nitrifier, helps the raising of system's denitrification efficiency.
2. improved the obstruction of reactor.
Emptying lay-up period at reactor has made up sufficient aerobic environment to the microorganism on the filler, can promote the oxygenolysis of mud self, prevents the obstruction of reactor.
3. simplified water distribution system, water distribution is even.
Because reactor is pressed periodic running, 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.
This reactor has been strengthened the reoxygenation usefulness of system, and the treatment efficiency of reactor is improved greatly, and it is dark to increase the pond, helps reducing taking up an area of, and reduces construction investment; Reactor does not have the energy consumption operation, and working cost is low; Convenient management.
