Description

A kind of suspending biochemical reactor

Technical field:

The utility model belongs to a kind of biochemical reactor, relates in particular to a kind of suspending biochemical reactor of handling waste water.

Background technology:

At present, the suspended substance in the use biochemical treatment waste water and the equipment of colloid thing mainly are compositions such as treating pond, settling tank, stirred pot, cool solarization pond, the processing power of FU volume is little like this, required equipment is huge, floor space is big, treatment scheme is numerous and diverse, has caused significantly improving of the initial cost expense in the waste water process handled.

Goal of the invention:

Goal of the invention of the present utility model provides that a kind of wastewater treatment capacity is big, volume is little, the suspending biochemical reactor of less investment.

Suspending biochemical reactor of the present utility model is by water-in, clear water output, sewage outlet, reactor, suspended lifter is formed, it is characterized in that reactor is taper, suspended lifter is equipped with in central authorities at reactor, reactor lower part is distributed with 2-10 water-in, on reactor top sewage outlet is arranged, clear water output is arranged on the sewage outlet, solid material leveller is equipped with at the reactor middle part, solid-liquid splitter is housed being positioned on the solid material leveller top of suspended lifter, solid-liquid separator is housed in the solid-liquid splitter, be the solid-liquid that the is installed on suspended lifter top device that backflows on the solid-liquid splitter, the clear water overflow weir be housed on the reactor top at clear water output place.

Aforesaid solid-liquid separator top is that filtering net, bottom are arranged is the casing of foul water tank.

Aforesaid water-in is peripheral uniform distribution at reactor bottom.

The working process of suspending biochemical reactor of the present utility model is:

Waste water is the uniform bottom that enters cone-shaped reactor of periphery by water-in, and rises to the top solid-liquid with the solid particulate that is stained with active sludge from its bottom under the screw machine castering action backflow the device in suspended lifter; The outstanding ability of liter of suspended lifter can be regulated by the variation that places its top motor speed, and returns the solidliquid mixture that falls and directly drop on the screen cloth of solid-liquid separator through the solid-liquid device that backflows; At this moment, the screen overflow solid particulate through solid-liquid separator stop directly fall into the center suspended lifter around, then directly fall into foul water tank but screen underflow is enriched with multiple tiny sedimentary dense thick sewage, discharge from sewage outlet; When the solid particulate that is stained with active sludge falls into the cone-shaped reactor that is full of for solidliquid mixture, solid level in the liquid is taken off flat for reciprocating solid material leveller periodically immediately, purifying waste water after these solid materialss filter discharged from clear water output down along peripheral overflow from top clear water overflow weir; The solid particulate that is stained with active sludge is the moving-bed downward movement in cone-shaped reactor, constantly adsorb simultaneously these various precipitated impurities from the waste water that water-in enters continuously, and then entrainmented from its bottom by the screw propulsion power of suspended lifter and upwards to be carried until the top solid-liquid backflows device through the suspended lifter central vertical, thereby finished circulation, reach continuous water inlet, blowdown goes out the purpose of clear water.

The utility model compared with prior art has following advantage:

(1) mechanical type spiral suspended lifter can be effectively and the internal recycle speed of regulating solidliquid mixture neatly, carries out the required Best Times of biochemical reaction to reach microbial bacteria.

(2) biological bacteria, fine suspension, tiny colloid and the tiny silicon salt throw out etc. that adhere to solid particles surface by the suspended lifter elevate a turnable ladder in the solid-liquid separator of top, under the back flushing effect that purifies clear water, separate through screen cloth, screen overflow can flow into cone-shaped reactor naturally for the solid particle that adheres to biological bacteria, screen underflow is tiny suspended substance, various colloids and silicon salt throw out then enter foul water tank and discharge automatically, thereby finish the purpose of purification.

(3) directive action of solid-liquid separator makes through the screen overflow behind the solid-liquid separator---solid particulate guide to fall into the centre suspended lifter around, guaranteed abundant isolation with clear liquid.

(4) the reciprocating machine formula of solid material leveller pushes away flat effect and has guaranteed in the cone-shaped reactor stablizing of internal recycle speed in constant and the outstanding riser of solid level.

(5) the long awl end of cone-shaped reactor and high dip angle have kept the basic reserve of Acarasiales solid materials and along the easy mobility of cone, and the Acarasiales solid materials that flows downward is to the absorption of various impurity such as fine suspension and contain upwards flowing of these impurity sewage and will have at this and be able in enough volumetrical cone-shaped reactors fully adsorb and separate.

(6) being provided with of circumference formula clear water overflow weir kept the constant of the smooth outflow of purifying waste water and liquid level, thereby guaranteed the resistance to overturning of the biochemical cone-shaped reactor operation of outstanding liter.

(7) the volume treatment capacity is big, and the facility investment of wastewater treatment is significantly reduced.

(8) be easy to assembling and combination, can a plurality of drum type brakes or the column edge type combination, strengthen processing power or the more senior purpose that purifies water to reach.
