Automatic continuous water treatment apparatus suitable for powder absorbent

Abstract

The invention discloses an automatic continuous water treatment apparatus suitable for powder absorbent. The automatic continuous water treatment apparatus comprises two reaction tanks, wherein each reaction tank is connected with a filter membrane, a powder absorbent is arranged in each reaction tank, the bottom of each reaction tank is provided with a waste water inlet pipe, a parsing liquid inlet pipe and a sludge discharging pipe, a backwash reflux pipeline is arranged between the bottom of the reaction tank and the bottom of the corresponding filter membrane, the top of the filter membrane is provide with the waste water outlet pipe, the bottom of the filter membrane is provided with the parsing liquid outlet pipe, the waste water inlet pipe, the parsing liquid inlet pipe, the parsing liquid outlet pipe, the sludge discharging pipe and the backwash reflux pipeline are respectively provided with a valve, and the filter membrane is connected with a backwash system. By adopting the automatic continuous water treatment apparatus, the continuous treatment for sewage can be realized, and the fluctuation of water quality and water quantity of a wider range can be treated; and the automatic continuous water treatment apparatus is suitable for the powder absorbent, directly applied to the water pollution governing engineering, does not need to form the absorbent, can alleviate the preparation difficulty of the absorbent, and can reduce the waste water treatment cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a continuous automatic water treatment device suitable for powder adsorbents. Background technique [0002] Adsorption technology is widely used in sewage treatment. It is involved in the treatment of heavy metal, high-salt and organic wastewater, and it is also used in the treatment of sewage in chemical, mechanical, and petroleum industries. In addition, in response to the national environmental protection call for water saving and energy saving, many companies have set up reclaimed water reuse treatment units, most of which use adsorption technology. [0003] Clay minerals exhibit good adsorption and ion exchange properties due to their unique layered structure, and have broad application prospects in wastewater treatment. Moreover, clay mineral adsorbents have a wide range of sources and low prices, and have always been known as the most promising adsorbents. Howev...

AI Technical Summary

Problems solved by technology

However, unlike activated carbon, clay minerals have good water absorption and swelling properties. Traditional molding methods applied to clay mineral molding often result in short molding duration due to clay water absorption and swelling. The more effective PVA method for clay molding is complex and expensive. , the cost of molding is several times the price of the clay itself, so it cannot be widely promoted

Formation difficulties limit the application of clay-based adsorbents in large-scale water treatment projects

[0005] The main reason for forming the adsorbent in the water treatment project is that it is difficult to eff
