Description

Defoaming device in a tank {device for weed out foam in cistern}

The present invention relates to a defoaming device in a bath, and in particular, a bath that floats on the surface of the remaining solution in the bath independently without a connection with a separate external system and automatically breaks and removes bubbles depending on whether bubbles are generated. It relates to a defoaming device within.

In general, industrial wastewater generated in the steel sheet manufacturing process is separated into oil and water is processed. In other words, the oil-containing wastewater transferred to the wastewater collection tank is decomposed and separated by adding sulfuric acid, and then flocculant is added to generate high particle sludge, which is pressurized to the pressure tank to separate the suspended sludge from the pressure flotation separation tank. The oil is separated by the primary treatment process, and the water is sent to a biological wastewater treatment tank for reprocessing by microorganisms.

This biological treatment process is based on the activated sludge process, where the activated sludge process is used to agitate wastewater in aeration tanks with activated sludge (a bacterial group that oxidizes sewage under aerobic conditions). By satisfying BOD (biological oxygen demand), colloidal or dissolved substances in waste water are precipitated or adsorbed on activated sludge to be purified.

The efficiency of the biological treatment process depends on how much the microorganisms are activated. The high concentration of alkali and surfactant added to clean the steel sheet causes excessive foaming even in a small impact, thereby failing to satisfy the environmental conditions in the biological treatment tank. In addition to profoundly affecting the activation of microorganisms, the severe foam generated until the end of the drainage has caused various problems such as violating environmental laws.

However, bubbles caused by surfactants, etc., which act as inhibitors of microbial activation, do not have any special removal technology except using antifoaming agents. When antifoaming agents are used, the COD (chemical oxygen demand) in the discharged water regulated by environmental law is increased. Problems are still occurring.

The problem of the foam generated in the crude preparation as described above occurs in aquaculture farms in addition to the industrial wastewater generated in the steel sheet manufacturing process.

In other words, tanks such as nursery farms, meat growth, storage tanks, abalone chives, cage farms, jara farms, and woong farm farms have accumulated a large amount of organic matter inside the tanks due to the excretion of fish and wastes. Nutrients such as carbon and ingredients) are mixed in water.

These organics have to be decomposed and discharged, and most of them are aerated to decompose and discharge organics. At this time, a large amount of bubbles are generated during the decomposition of organic matter, and the bubbles generated at this time function as water and air shields in the water tank, thereby reducing the residual amount of dissolved oxygen.
