Problems solved by technology

[0003] Traditional phosphorus removal methods are mainly divided into three methods: biological method, chemical method, and adsorption method. The existing wastewater phosphorus removal effect is not ideal, and the cycle is long and expensive. Therefore, the present invention provides a phosphorus-containing wastewater treatment method , so that the treatment effect of phosphorus-containing wastewater is good, and at the same time, the phosphorus-containing sludge produced can be used as a fertilizer raw material after drying

Embodiment Construction

[0023] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0024] Embodiments of the invention include:

[0025] Described a kind of phosphorus-containing wastewater treatment process, comprises the steps:

[0026] Step 1: Concentrate the phosphorus-containing wastewater into the raw water tank of the phosphorus-containing wastewater through pipelines. The raw water tank adopts a cylindrical or cuboid structure, and the surrounding walls are made of concrete structure, and the depth is between 3 and 5 meters.

[0027] Step 2: Introduce the water in the raw water tank into the filter tank, set up a fence structure in the filter tank, intercept the large sludge and solid blocks, and use photocatalysis for sterilization treatment, and transport the large s...

Abstract

A treating process for phosphorus-containing waste water is disclosed. The process includes steps of centralizing the phosphorus-containing waste water into a raw water tank, feeding water in the raw water tank into a filtering tank and an aeration neutralization reaction tank, feeding the waste water flowing through the aeration neutralization reaction tank to an aeration reaction tank through a pipeline, adding a precipitating agent, precipitating, feeding the waste water into a hydrolysis tank through a pipeline, feeding the waste water into an intermediate tank, feeding into a multi-stage oxidation tank through a pipeline, feeding the waste water flowing through the multi-stage oxidation tank to a second immediate tank, feeding the waste water to a sand filter, feeding purified water into an activated carbon filter, and feeding the waste water flowing through the activated carbon filter to a safeguard filter. The process is reasonable in process design, low in running cost and convenient to manage. A phosphorus product can be recovered and reutilized.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a phosphorus-containing wastewater treatment process. Background technique [0002] In the fertilizer manufacturing industry, a large amount of wastewater is discharged from the production of phosphoric acid plants in factories. At the same time, in the coating industry, spraying steel pipes, electroplating industry, and electronic product etching process, there is a large amount of phosphorus-containing wastewater. The main component of phosphorus-containing wastewater is phosphate ions and hypophosphite ions, the discharge of phosphorus-containing wastewater will lead to eutrophication of water bodies, cause environmental pollution, and affect the development of aquaculture. Therefore, it is necessary to treat phosphorus-containing wastewater to meet national standards before it can be discharged. [0003] Traditional phosphorus removal methods are mainly divided into th...
