Technical field

The present invention relates to water, the biological process of waste water or sewage is handled, and is particularly useful for the processing to aquaculture water.

Background technology

In culture fishery, the breed water that in fish or benthonic hydrocoles breeding process, is discharged for example, owing to wherein contain the ight soil of cultivated animals and residual bait, chemical transformation takes place in these organism in water, produces ammonia nitrogen and other toxic substances.If recycling, carry out biological process again after it is filtered and handle the security level that reaches the cultivated animals growth and live.Water is cultured in recycling, not only reduces environmental pollution, and water saving is if can also save a large amount of energy in winter.The biological process treatment unit of prior art is to fill up activated carbon in dark about two a meters big cement tub or big jar, coral sand, fluorite, ceramic ring, biological ball etc., the characteristics of these materials are porous cracks, adsorption is arranged again, when passing through these fillers through filtering breed water, nitrobacteria in the water is deposited, their rely on to be cultured ight soil residual in water and residual bait fine particle and survive and breeding in a large number, and make that organic substance is transformed into mineral salt and gas in the water, avoid generating ammonia nitrogen and other toxic substances.But the biological process treatment unit of this breed water has following shortcoming: since be equipped with filler groove or jar etc. bulky, be dark 2 meters wide 2 meters as a cement tub, long 3～5 meters, in cement tub, fill up above-mentioned filler, because it is bulky, even a plurality of water-ins and water outlet are arranged, also can make current inhomogeneous, the dead angle is too many, current less than dead angle place just be not easy to growth and the breeding of nitrobacteria, the place that current are big is not easy again nitrobacteria is retained, and this will have a strong impact on the biological process treatment effect of water; Secondly, because the groove of this biological process processing or jar, nearly 2 meters of the degree of depth at depth of water place, owing to be difficult for and air inerchange oxygen, will influence life and the breeding of near the nitrobacteria in this place, also can reduce the biological process treatment effect of water; The 3rd, this huge groove or jar through will cleaning after the running is after a while all routed up about tens cubic metres or more filler and to be cleaned the very bothersome and cleaning that will stop production; The 4th, again because described groove or tank volume are too big, current are inhomogeneous, in the biological process process, resultant stops up the water route easily, generally speaking, after after a while, to recoil to tank or jar with pressure water, its result is easy to generate the cavity, and current are short-circuited, and causes the biological process treatment effect of water to descend.

Summary of the invention

The objective of the invention is to: provide a kind of multilayer drawer type cultural aquatic organism method treatment unit for the shortcoming that overcomes prior art, make its easy and atmosphere generation gaseous interchange in the biological process treating processes, improve the biological process processing efficiency of water, make its device convenient when cleaning, and do not stop production, can also make these device current even, not produce the dead angle, not produce current short circuit or latch up phenomenon.

The present invention can reach by following measure:

A kind of biological process treatment unit of multilayer drawer type cultural water, it is characterized in that, the cabinet type casing that the multi-layer drawers duct is arranged from bottom to top, in each drawer duct, place a drawer with wall and bottom surface, fill up activated carbon in the described drawer, coral sand, fluorite, ceramic ring, filler and mobile breed water such as biological ball, terminal bottom at drawer is provided with rising pipe, each drawer duct upper front end is provided with the water-supply pipe of band water jet, a plurality of water-supply pipes and connect the back by working shaft with culture water and gather case and link to each other, cabinet type housing seat is in the tank of energy draining.

Also two transverse walls can be set near the rising pipe of described drawer, be lower than drawer side wall end face one segment distance, exceed drawer bottom surface one segment distance away from the lower surface of the transverse wall of rising pipe near the upper end of the transverse wall of rising pipe.

The present invention compared with prior art has following advantage:

At first, because culturing the biological process processing of water is to carry out in the multi-layer drawers of a plurality of parallel connections, the degree of depth of drawer has only 80～150 millimeters, even the undermost breed water of drawer is also easy and atmosphere carries out gaseous interchange, therefore the oxygen content in the water is just many, growth to nitrobacteria is highly beneficial with breeding, and its biological process treatment effect is better; The second, because each drawer can at will be extracted out, observe and convenient management, eliminate the latch up phenomenon of resultant at any time, therefore do not need filler is recoiled; The 3rd, very convenient when apparatus of the present invention are cleaned, as long as extract drawer out, filler is poured out, drawer is cleaned, again the filler that the cleaned drawer of packing into, put back in the drawer hole and get final product, owing to each drawer all is and even, so need not stop production during cleaning; The 4th, again because the end of drawer of the present invention is provided with two transverse walls, its end face near the transverse wall of water outlet is lower than drawer wall end face one segment distance, and the lower end away from the transverse wall of water outlet exceeds drawer bottom surface one segment distance again, like this when changing water, make current even, the water in the drawer can discharge in order, does not produce the dead angle, this just makes each position of drawer nitrobacteria all be arranged at vigorous growth and breeding, has improved water treatment efficiency greatly.
