Description

A kind of sewage draining exit processing unit

Technical field

The invention belongs to environmentally friendly water-treatment technology field, the sewage draining exit of the water bodys such as river course, lake, plant is mainly used in Treatment.

Background technology

The surface water such as the river, lake, reservoir, pond of China mostly have serious pollution.It is substantial amounts of unprocessed Trade effluent, sanitary sewage, agricultural irrigation after water be directly discharged into river, river, lake, sea, cause water pollution, black and odorous water.With The continuous intensification of Urbanization in China, urban wastewater discharge is constantly raised, current municipal sewage be all much without appoint Where reason is directly discharged to river course nearby, and many city rivers are presented black smelly situation, although government has carried out a section dirt, but cuts It is dirty not thorough, cut a dirty incomplete phenomenon and be still present, untreated sewage enters river course, so as to be further water ecology Reparation causes difficulty.

Sewage draining exit treatment is necessity and beneficial complement that water ecology is repaired, or even has become water ecology and repair into The key for losing, the water ecology reparation of dirty and sewage draining exit treatment is not cut fully, and the impact resistance of system is poor, and black returning is returned again Smelly phenomenon happens occasionally.

Chinese invention patent CN205347124U, the sewage of sewage draining exit is processed using the method for sewage treatment plant, but Because system needs substantial amounts of capital construction, power supply and floor space big, the sewage draining exit treatment of city river is not appropriate for；China Patent of invention CN205313327U is processed sewage draining exit using the technology of isolation net cage and microorganism colonization, but due to Less, the impact resistance to pollutant is poor, so that regulation effect is undesirable for the area of microorganism colonization.

Anaerobic processes are always the significant process of sewage disposal, and it is more organic than the aerobic process difficult degradation that can more fully degrade Matter, more save energy, have good degradation capability for excrement class, plant residue class, high protein content class waste water.Pass through Debirs resolve into anaerobic processes, anaerobe the nutrition and gas that can be dissolved, gas include methane, carbon dioxide, Vapor, a small amount of sulfur dioxide and nitrogen.

The invention provides a kind of sewage draining exit processing unit, the device is capable of the waste water of efficient degradation sewage draining exit, particularly Remaining sewage after treatment section dirt is not thorough.

The content of the invention

The invention provides a kind of sewage draining exit processing unit, it is characterized in that using anaerobic digestion, the device includes：Two sets Inner bag and outer bag together, the flange connection of sack, water discharge pipe, gas outlet pipe, automatic pulse ignitor, self-timing Draining valve is constituted.Sewage draining exit waste water enters inner bag, and deposit is precipitated in inner bag, and gas and water after treatment enter outer bag, gas Extend mouth discharge by entering gas after gas outlet pipe, self-timing draining valve is according to specific time draining.

In said apparatus, using bagging, including inner bag and outer bag, the maximum volume of inner bag generally should be smaller than the maximum of outer bag Volume, inner bag can only allow gas and liquid to pass through, it is impossible to allow solid to pass through, i.e. inner bag can only intercept solid, and outer bag can not allow gas Body and liquid pass through, i.e., outer bag can intercept gas and liquid.

In said apparatus, inner bag may be reversed, the waste discharge that the solid waste in bag or anaerobic digestion are produced, or use Blowdown is pumped out.

In said apparatus, the material of inner bag is the material that can intercept solid, such as non-woven fabrics, and the material of outer bag is to hinder Every liquid or the material of gas, such as ethylene propylene diene rubber（EPDM）.

In said apparatus, the flange of sack connects one end and is tightly fastened with inner bag and outer bag, and the other end is installed with sewage draining exit Flange connection be connected, flange connection the device can be made closely coupled with sewage draining exit, prevent big flow sewer from washing away device.

In said apparatus, one end of water outlet is connected with outer bag bottom, and the waste water for being beneficial to generation is discharged along gravity, separately One end is connected with self-timing draining valve, and the water discharge time of self-timing draining valve is according to the capacity of outer bag and the flow of sewage draining exit Set, such as the average discharge of sewage draining exit is the 1/7 of outer bag capacity, and outer bag may be set to draining of each Zhou Jinhang.

In said apparatus, there is gas collection mouthful in the top of outer bag, methane that the device is produced, carbon dioxide, nitrogen, The gases such as hydrogen, hydrogen sulfide, oxygen, these lighter-than-air gases are easy to be discharged by gas collection mouthful, and hydrogen sulfide etc. Heavier-than-air gas is easily soluble in water, and the gas that gas collection mouth is collected into enters autompulse point by gas outlet pipe Firearm is lighted.

In said apparatus, automatic pulse ignitor and self-timing draining valve use rechargeable battery or battery, so that Whole device is unattended and without power supply.

In said apparatus, gas outlet pipe can be one or more, around device.

In said apparatus, water discharge pipe can also be one or more, and around device, the water of discharge can enter one Stepping enters wetland, soil etc. carries out advanced treating.

Compared with prior art, the beneficial effects of the invention are as follows：

1. efficiently decontamination：Anaerobic Treatment process can decompose the organic matter of complexity, and sludge growth rate is small, to sewage disposal than good Oxygen is efficiently, simple and easy to apply, is flexibly applicable big small-scale.

2. require that space is small：Anaerobic Treatment volumetric loading rate improves the demand reduction to space, while sludge stabilization is good, Surplus sludge volume is few, with good dewatering, is conducive to the final disposal of sludge.

3. energy consumption is low：The present apparatus is almost unpowered operation, and energy consumption is extremely low, it is only necessary to several batteries or dry cell.

4. simple and easy to apply：Device materials in the market of the invention can buy, easy to process, simple and easy to apply.

5. with low cost：Device non-woven fabrics of the invention, ethylene propylene diene rubber etc. are cheap, easy to process.

6. operation maintenance is convenient：The present invention can be employed without for a long time in theory due to non-woven fabrics, the retractility of rubber Draw the bed mud of inner bag.
