The application belongs to the technical field of water treatment, and relates to a biofilm electrochemical reactor for simultaneously removing nitrate nitrogen and trace organic matters in water. According to the principles of electrochemical reaction and products completely different under different cathode and anode material conditions, the reactor is divided into three functional regions, wherein first, an electrochemical reaction of producing hydrogen at a cathode and decomposing carbon at an anode is realized in a first functional region so as to provide a condition for reduction of nitrate nitrogen by a hydrogen autotrophic denitrifying bacteria of a particle electrode layer in a second functional region, after products generated by means of the electrochemical reaction and a biochemical reaction in the previous two functional regions enter a third functional region, pollutants such as trace organic components and residual ammonia nitrogen in water are oxidized and decomposed by using anodic oxidation function.

A water filtering system includes providing light deep into a liquid used in applications such as the cultivation of both attached and suspended photosynthetic organisms. The system is configured to inject a stream of bubbles into the liquid and a light source is configured to shines light through the bubbles. The bubbles allow some light to travel deep into the liquid along the length of the bubble stream and scatter/deflect some light out of the bubble stream and into the surrounding liquid including screens for growing algae.

Disclosed is an energy hydrogen water dissolving device that passes a clean water source through a pressurized pump. A part of the water is sent to a hydrogen production equipment and decomposed into hydrogen and oxygen, and the other part of the water is driven to an energy hydrogen water dissolving and storage tank. The oxygen formed by the hydrogen production equipment is discharged to the outside or returned to the clean water source, and the hydrogen formed by the hydrogen production equipment is connected and sent to an input end of the pressurized pump, pressurized and mixed uniformly by the pressurized pump and outputted to the clean water, so that the water liquid entering into the energy hydrogen water dissolving and storage tank becomes high dissolution hydrogen water. The energy hydrogen water dissolving and storage tank contains an energy mineral, a hydrogen molecule mineral and a terminal filter, and the water liquid discharged from the energy hydrogen water dissolving and storage tank is formed into healthy drinking water with tiny water molecules, weak alkaline, high negative potential and high dissolution hydrogen molecules
