Biological treatment device for multilayer drawer type cultural water

Abstract

The invention discloses a biological method treating device of multi-ply drawer type cultivating water, which relates to water, waste-water or sewage water biological method treating. The invention is characterized by the following: there is a cabinet type box with top-down multi-ply drawer pore passages; the drawer with four walls and floor is installed in every drawer pore path; the drawer is filled with floating culture water and extender including active carbon, coral sand, fluorite, ceramic ring, biological ball; there is a exhaust pipe at the end of the drawer; the upper front end of every drawer pore passage installs supply pipe with water jet; many supply pipes are connected and then connect to culture water collecting box through make-up pump; the cabinet type box seat is in water bath of water drain.

Description

technical field [0001] The invention relates to biological treatment of water, waste water or sewage, and is especially suitable for the treatment of aquaculture water. Background technique [0002] In the aquaculture industry, for example, the aquaculture water discharged during the breeding of fish or benthic aquatic animals contains feces and residual bait of farmed animals, and these organic substances undergo chemical changes in the water to produce ammonia nitrogen and other toxic substances . If it is to be reused, it must be filtered and then processed by biological methods to achieve the safe level of growth and life of farmed animals. Reusing aquaculture water not only reduces environmental pollution, saves water, but also saves a lot of energy in winter. The biological treatment device of the prior art is to fill a large cement tank or a large tank about two meters deep with active carbon, coral sand, fluorspar, ceramic rings, biological balls, etc. The characte...

Problems solved by technology

[0003] The purpose of the present invention is: in order to overcome the shortcoming of prior art and provide a kind of multi-layer drawer type aquaculture water biological treatment device, make it easy to produce gas exchange with atmosphere in the biological treatment process, improve the biological treatment efficiency of water , so that the device is convenient for cleaning and does not stop production. It can also make the water flow of the device uniform, without dead angle, short circuit or blockage of water flow.
