Problems solved by technology

[0004] The purpose of the present invention is to provide a method for treating industrial sewage using microbial preparations, which has the advantages of strong corrosion resistance of sewage pipes, relatively thorough sewage treatment, and no residual air bubbles. Brine contains a large amount of corrosive ions such as Cl-, which causes the problem of thinning and perforation of the pipe wall

Embodiment 1

[0022] The present embodiment provides a kind of method utilizing microbial agent to carry out industrial sewage treatment, comprises the following steps:

[0023] 1) Pretreatment: First, the industrial sewage is passed through a solid-liquid separator for solid-liquid separation to remove large solid particles, and then the liquid enters the sedimentation tank for 12 hours of precipitation, and then the liquid is passed through a round hole filter to remove solid flocs;

[0024] 2) Secondary treatment: pump the obtained wastewater to the primary sedimentation tank, add a precipitant to the primary sedimentation tank to remove heavy metal ions calcium ions, magnesium ions, barium ions, and lead ions in the wastewater, and pass the wastewater into the Adjust the water quality and quantity in the regulating pool, and control the waste water in the pool for 10 hours;

[0025] 3) Discharge the secondary treated sewage into the treatment tank, put the corrosion inhibitor and microb...

Abstract

The invention discloses a method for treating industrial sewage by a microbial preparation. The method comprises pretreatment: carrying out solid-liquid separation on industrial sewage through a solid-liquid separator to remove large solid particles, feeding the liquid into a sedimentation tank, carrying out sedimentation for 12-15 hours and then removing the solid floc in the liquid through a round hole filter net, and secondary treatment: pumping the obtained wastewater into an initial sedimentation tank through a water pump, adding a sedimentation agent into the initial sedimentation tank,removing heavy metal ions such as calcium ions, magnesium ions, barium ions and lead ions in the wastewater, feeding the filtered wastewater into a regulating tank, and adjusting the water quality andquantity, wherein the time for controlling the wastewater in the pool is 10-20 hours. The method utilizes a corrosion inhibitor. The ingredients of the corrosion inhibitor have strong oxidizing properties and can react with metals without contacting with oxygen to form a dense oxide film on the metal surface so that the purpose of preventing corrosion and rust on the surface of the pipe is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating industrial sewage by using microbial preparations. Background technique [0002] Sewage, usually refers to waste water from domestic and production that is polluted to a certain extent. Sewage mainly includes domestic sewage and industrial wastewater. Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants emitted by industry. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even in the same factory, the quality and quantity of polluta...
