Description

The heating-type integrated sewage treating apparatus

Technical field

The present invention relates to the anaerobic waste water biologic treating technique, concretely, is a kind of new and effective two-phase integrated sewage treating apparatus.

Background technology

Traditional diphasic anaerobic reaction process is divided into acidication and produces two processes of methane, and these two process needs carry out in two independent reactors respectively.The acidication process is mainly the biodegradability that improves matrix, provides suitable matrix for producing methane; Producing methane and mainly be the substrate conversion that acidization provides is methane, and both constitute the diphasic anaerobic reaction process jointly.

At present, the two-phase integral anaerobic reactor is a kind of new and effective anaerobic waste water treatment facility, acidifying and two technologies of product methane are finished in a reactor, its decoration form commonly used is vertical or telescoping structure, exists problems such as complex structure, installation difficulty are big, mass transfer effect difference; On the other hand, sewage directly inserts acidification pool by pipeline, and especially in temperature lower winter, the sewage water temperature is on the low side to be unfavorable for the generation of acidifying bacterium the treatment effect of reactor being reduced greatly.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, mass transfer effect good, processing power is strong two-phase integral anaerobic reactor.

For achieving the above object, the technical solution used in the present invention is: a kind of heating-type integrated sewage treating apparatus, comprise reactor (1), water-in (2), water outlet (3), gas collection mouth (4) and mud discharging mouth (5), key is: described reactor (1) is divided into hydrolysis acidification pool (1a) by the dividing plate (6) of vertical setting, produce methane pond (1b) and zone of transition (1c), the top of described hydrolysis acidification pool (1a) is communicated with by the bottom of described zone of transition (1c) with described product methane pond (1b), be provided with agitator (7) and coil pipe (8a) in the described hydrolysis acidification pool (1a), the solar heat-collection plate (8b) that described coil pipe (8a) is outer with being arranged on described reactor (1), pressure pump (8c) constitutes heat-exchange system (8) jointly, and the middle part in described product methane pond (1b) is provided with filler (11).

Anaerobic biological treatment is divided into acidication and produces two stages of methane, the present invention is by the reactor of integrated design, acidication with produce methane and be combined in the reactor and finish, so can make the left part of reactor and the optimum growh environment that right part satisfies acid-producing bacteria and methanogen respectively, in a reactor, realize producing acid phase and effective separation of producing the methane phase.Sewage enters acidification pool from water-in, under the stirring of agitator, carry out abundant heat exchange with the high temperature coil pipe, the rising of temperature helps sewage at the acidification pool acid-producing bacteria, flows into zone of transition from the top down through the acidification pool pretreated sewage, enters from the bottom of producing the methane pond and produces the methane pond; Discharge from the gas collection mouth through the methane gas that produces after the methane pond transforms, the sewage after handling is then discharged from water outlet, discharges by mud discharging mouth behind the sludge settling.Filler is used for attached microbial, forms microbial film, reduces the loss of reactor microorganism, strengthens the water outlet quality.

Described reactor (1) is cylindrical and have a bottom of back taper, totally two and be separately positioned on described hydrolysis acidification pool (1a) and produce methane pond (1b) bottom of described mud discharging mouths (5).Reactor is arranged to have the round shape of back taper bottom, helps mud and discharge, avoid forming the dead angle along the scarp precipitation of back taper bottom and through two mud discharging mouths; Simultaneously, the reactor good looking appearance, and make things convenient for monolithic molding.

The position that described zone of transition (3) is communicated with described product methane pond (1b) is provided with first flow deflector (9) and second flow deflector (10), the lower end of described first flow deflector (9) tilts towards described product methane pond (1b), and described second flow deflector (10) is horizontally installed on the below of first flow deflector (9).Two flow deflectors are arranged on zone of transition and produce the position that the methane pond is communicated with, and sewage has been played good guide functions, have avoided sewage to be deposited on reactor bottom and have formed stagnant water.

As preferably, described heat-exchange system (8) also comprises temperature control meter (8d) and coil pipe support (8e), the coil pipe support is used to support coil pipe is stabilized in the hydrolysis acidification pool it, the temperature control meter is used to control sewage and is in all the time in the suitable water temperature range, avoid the water temperature rapid drawdown that rises sharply, fluctuation is too big and influence the growth of acidifying bacterium.

Beneficial effect of the present invention:

1) place same reactor to finish acid-producing bacteria and methanogen, reduced reactor quantity, solved traditional diphasic anaerobic technique owing to the construction of adopting two separate reactors to cause and working cost height, problem that floor space is big, thereby whole construction costs and maintenance cost are obviously reduced.

2) zone of transition by being provided with between hydrolysis acidification pool and product methane pond makes sewage flow into the bottom of producing the methane pond from top to bottom, improves the mass transfer effect between mud and the water, improves reaction efficiency;

3) absorb heat to improve sewage temperature by solar heat-collection plate, help acid-producing bacteria and methanogen, increase the biomass of two technological processs, further improve effluent quality, and very energy-conserving and environment-protective.

In sum, simple in structure, advantages such as mass transfer effect good, processing power is strong, energy-conserving and environment-protective that the present invention has have vast market prospect.
