Abstract

An active photocatalytic reactor configured to process biological culturing water with an accelerated process. Water to be used in a biological culturing system is stabilized with pollutants in the water reduced. The active photocatalytic reactor is less affected by outside environment while having faster activating speed. The active photocatalytic reactor can further be combined with a traditional filter to form a serial or parallel connection for more effectively purifying the culturing water with damage to the whole system avoided.

First claim

What is claimed is:

1 . A method of processing culturing water using an active photocatalytic reactor and a biological culturing system wherein culturing water is input into the active photocatalytic reactor to purify waste material in the culturing water and directed onto a surface of a photocatalyst disk of the active photocatalytic reactor to a depth not exceeding 5 mm, wherein the surface of the moving photocatalyst disk comprises fixed photocatalyst and wherein the disk is smaller than 50 cm in diameter and rotates at more than 100 rpm; and
irradiating the surface of the moving photocatalyst disk and the culturing water with a ultra-violet (UV) lamp so as to purify the culturing water; wherein the waste material is a compound or a combination of compounds selected from a group consisting of NH 4 , NH 3 , NH 2 and NH; and wherein, after purifying the culturing water, the culturing water is recycled to be outputted from the active photocatalytic reactor.

2 . The method of claim 1 , wherein the biological culturing system has a culture system inlet and a culture system outlet; wherein the active photocatalytic reactor has a photocatalytic reactor inlet and a photocatalytic reactor outlet; wherein the culture system inlet is connected with the photocatalytic reactor outlet through a first cycling route; and wherein the culture system outlet is connected with the photocatalytic reactor inlet through a second cycling route.

3 . The method of claim 2 , wherein the photocatalytic reactor outlet is connected with a draining tube having a control valve.

4 . The method of claim 2 , wherein a water filter is further combined between the biological culturing system and the active photocatalytic reactor and the water filter has a water filter inlet and a water filter outlet; and wherein the culture system inlet is connected with the photocatalytic reactor outlet and the water filter outlet through a third cycling route; the culture system outlet is connected with the photocatalytic reactor inlet and the water filter inlet through a fourth cycling route; and a parallel connection is thus obtained with the biological culturing system, the active photocatalytic reactor and the water filter.

5 . The method of claim 4 , wherein the photocatalytic reactor outlet and the water filter outlet are separately connected with draining tubes each having a control valve.

6 . The method of claim 2 , wherein a water filter is further combined between the biological culturing system and the active photocatalytic reactor and the water filter has a water filter inlet and a water filter outlet; and wherein the culture system inlet is connected with the photocatalytic reactor outlet through a fifth cycling route; the culture system outlet is connected with the water filter inlet through a sixth cycling route; the photocatalytic reactor inlet is connected with the water filter outlet through a seventh cycling route; and a serial connection is thus obtained with the biological culturing system, the active photocatalytic reactor and the water filter.

7 . The method of claim 6 , wherein the photocatalytic reactor outlet is connected with a draining tube having a control valve.

8 . The method of claim 1 , wherein the culturing water has a pH value between 6 and 8.

9 . The method of claim 1 , comprising inducing any excess culturing water to leave the surface of the rotating photocatalyst disk via centrifugal force.

10 . The method of claim 1 , comprising directing the culturing water onto an upper surface of the rotating photocatalyst disk.

11 . The method of claim 1 , comprising irradiating an upper surface of the rotating photocatalyst disk with the UV lamp.

12 . A method of processing culturing water using a backup active photocatalytic reactor with a reactor inlet and outlet and a biological culturing system with a culturing system inlet and outlet
wherein the culturing system inlet is connected with the reactor outlet via a first circuit and wherein the culturing system outlet is connected with the reactor inlet through a second circuit and wherein culturing water is input into the active photocatalytic reactor to purify waste material in the culturing water and directed onto a surface of a photocatalyst disk of the active photocatalytic reactor to a depth not exceeding 5 mm, wherein the surface of the moving photocatalyst disk comprises fixed photocatalyst and wherein the disk is smaller than 50 cm in diameter and rotates at more than 100 rpm; and irradiating the surface of the moving photocatalyst disk and the culturing water with a ultra-violet (UV) lamp so as to purify the culturing water; wherein the waste material is a compound or a combination of compounds selected from a group consisting of NH 4 , NH 3 , NH 2 and NH; and wherein, after purifying the culturing water, the culturing water is recycled to be outputted from the active photocatalytic reactor.

13 . The method of claim 12 , wherein the reactor outlet is connected with a draining tube having a control valve.

14 . The method of claim 12 , further comprising a first water filter connected between the biological culturing system and the reactor and wherein the water filter has a water filter inlet and a water filter outlet; and wherein the culturing system inlet is connected with the reactor outlet and the water filter outlet through a third circuit; and the culturing system outlet is connected with the reactor inlet and the water filter inlet through a fourth circuit so as to define a back-up parallel connection of the biological culturing system, the reactor and the water filter.

15 . The method of claim 14 , wherein the reactor outlet and the water filter outlet are separately connected with draining tubes each having a control valve.

16 . The method of claim 14 , further comprising a second water filter connected between the culturing system and the reactor and the second water filter has an inlet and outlet; and wherein the culturing system inlet is connected with the outlet through a fifth circuit; the culturing system outlet is connected with the water filter inlet through a sixth circuit; the reactor inlet is connected with the water filter outlet through a seventh circuit; so as to define a serial connection of the biological culturing system, the reactor and the water filter.
