The utility model discloses a reclaimed water treatment device adopting an integral membrane biological reactor, belongs to a sewage and waste water treatment device and particularly relates to the reclaimed water treatment device using the membrane biological reactor. The reclaimed water treatment device adopting the integral membrane biological reactor is characterized in that a fan mounted on one side of a biochemical regulation pool is connected with an aeration device at the bottom of the pool through an air conveying pipeline, a water pump positioned at the bottom of the pool is connected with a water inlet of the membrane biological reactor through a sludge-water mixing pipeline, and a concentrated solution reflux pipe connected with a concentrated solution outlet of the membrane biological reactor leads to the biochemical regulation pool. Water inlet, regulation and biochemistry of the sewage treatment system are completed in a structure, sludge-water separation, filtration and the like are performed on a sludge-water mixture in the biochemical pool in a membrane pipe of an external membrane biological reactor, the system can break through the form of the traditional sewage treatment system, does not need to increase an independent regulation pool, a secondary sedimentation pool, a filtering pool, a sludge return pool, a sludge treatment unit and other structures and has the characteristics of small floor area, low investment, low operation cost and the like.

Description

Water treating equipment in the integral type film biological reactor

Technical field

The utility model belongs to the sewage and waste water treatment facility, particularly a kind of middle water treating equipment that use membrane bioreactor.

Background technology

Along with the development of town and country industrial or agricultural construction and domestic life Facilities Construction, the consumption of water resources is increasing, practices thrift preferential water resources and WWT is utilized has again become a major issue.With sewage, waste water and the part trade effluent of urban and rural residents as in the water source, through reaching the water quality standard of reclaimed water after purifying, can alleviate the situation of water scarcity, can play the purpose that prevents water pollution and protect environment simultaneously.For sewage is purified; Multiple Sewage treatment systems is arranged; Like traditional active sludge processing system, A/O process system, A2//O denitrification dephosphorization technique system, oxidation ditch process system, absorption biological degradation treatment process system and intermittent activated sludge treatment system; Shortcomings such as above Sewage treatment systems is mostly carried out water treatment procedure in single coenocorrelation, ubiquity investment is big, complex process, degradation rate are low.

The utility model content

In order to overcome the deficiency of existing middle water treating equipment complex process, degradation rate, the utility model provides water treating equipment in a kind of integral type film biological reactor, and the water treating equipment technological process is simple in this integral type film biological reactor, treatment effect good.

The utility model solves the technical scheme that its technical problem adopted: water treating equipment in a kind of integral type film biological reactor; It is characterized in that: the blower fan that is installed in biochemical equalizing tank one side links to each other with aerating apparatus at the bottom of the pond through the wind conveying pipe road; The water pump that is positioned at the bottom of the pond is connected with the membrane bioreactor water-in through the muddy water mixing duct, and the liquid concentrator return line of the concentrated solution outlet connection of membrane bioreactor is towards biochemical equalizing tank.

Be provided with aerating apparatus in the utility model mesophytization equalizing tank bottom; Blower fan is that mikrobe provides oxygen in the biochemistry pool through aerating apparatus, sewage get into biochemical equalizing tank fully with the pond in mikrobe contact, mikrobe is decomposed into water and CO2 with the organism part in the water; A part is used for the nutritive substance of self growing; Convert a large amount of active sludge into, remove pollutent and also reduce Pollutant levels, mud and the abundant thorough mixing of water in the biochemical equalizing tank under the stirring of aerating apparatus; Mud mixture is promoted in the film pipe of membrane bioreactor via water circulating pump; Under the driving of pressure, carry out mud-water separation, water outlet sees through film and gets into product water tank qualified discharge, and mud and liquid concentrator are back to biochemical equalizing tank and continue to participate in the biochemical treatment reaction.

Water treating equipment in the disclosed integral type film biological reactor of the utility model have the following advantages:

1, the water inlet of this Sewage treatment systems, adjusting, biochemistry are accomplished in structures; The biochemistry pool mud mixture carries out mud-water separation in (MBR) of external membrane bioreactor film pipe; Filter etc.; Native system has been broken traditional Sewage treatment systems does not need to set up structures such as separate regulating pond, second pond, filtering basin, mud backflow pool, sludge treatment unit again, has that floor space is little, characteristics such as reduced investment, working cost are low.

2, native system has the advantage of intermittent activated sludge treatment process, can realize in biochemical equalizing tank that the nitration denitrification effect reaches the effect of denitrogenation dephosphorizing.

3, because the interior sludge blanket of biochemical equalizing tank is thicker, and sludge age is long, and sludge retention time is long, mud produces digestion reaction in biochemistry pool, so the native system sludge output is less.

4, native system is made up of biochemical equalizing tank and external MBR film guard system two portions, has simplified treatment scheme, and is simple to operation, greatly reduces the hand labor force intensity.

5, the COD clearance reaches more than 80%, and the BOD clearance reaches more than 85%, and ammonia nitrogen removal frank reaches 90%-95%, and the clearance of phosphorus reaches 50%-60%, and degradation rate is high, and treatment effect is good.

6, activated sludge concentration is high in the native system biochemistry pool, and sludge age is long, and it is strong that sewage quality is changed adaptive faculty, and hole impact load ability is strong.
