Aerating equipment for controlling water pollution

Abstract

The invention discloses aerating equipment for controlling water pollution. The aerating equipment for controlling water pollution comprises a sewage pond, a wall body, a mounting rack, a speed controlling chassis and impellers, wherein an aerating pump is arranged on the top of the wall body, one side of the aerating pump is connected to a hose, an aerating pipe is mounted at the bottom end of the hose, the mounting rack is arranged on one side of the aerating pump, the mounting rack is mounted in the wall body, a rotary shaft is arranged in the mounting rack, a first belt wheel is mounted onthe top end of the rotary shaft, and the first belt wheel is mounted in the speed control chassis. The aerating equipment disclosed by the invention has the beneficial effects that by designing the aerating pipe and the impellers, fine bubbles are formed in water and float upward to pass through a water layer; the water surface is severely stirred by means of the impellers and new liquid interfaces are in contact with atmosphere continuously, so that the contact area with water is large; and the aerating equipment plays a stirring role to prevent wastewater from being corroded, so that the active sludge of the treated sewage is maintained in a suspended state, and therefore, the treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to an aeration device for water pollution control. Background technique [0002] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. Wastewater has different classificati...

Problems solved by technology

[0003] The aeration equipment in the prior art has the following problems: 1. The method of underwater aeration is insufficient in contact with the air, the aeration effect is poor, and it is difficult to adapt to the deep water area, and it is difficult to act on the surface of the sewage; 2. If the agitator is used Pressurized gas-liquid two-phase mixing with mixer, high processing cost and large investment
