Problems solved by technology

Most of the existing treatment methods are to use chemical flocculation to treat suspended solids; to use flocculation and sedimentation to treat organic matter; to use ion exchange resin to treat ammonia nitrogen. These methods have the characteristics of large investment, incomplete treatment and high cost of use.

Embodiment Construction

[0011] 1. The water source is domestic sewage

[0012] 2. Use double filter towers as water pollution treatment equipment

[0013] Structure: The double filter tower is mainly composed of four parts: filter tower body, pipeline, backwashing equipment and automatic control device. The inner part of the filter tower is divided into the pre-filtration water cavity area, the upper filter material layer, the lower filter material layer and the post-filtration water collection area. The domestic sewage inlet is provided with an overflow pipe.

[0014] The main technical parameters:

[0015] Equipment specification: ∮2000mm×2500mm

[0016] Single tower processing capacity 60m 3 / h, hydraulic velocity V=15m / h

[0017] Filter material: blast furnace heavy slag 440mm, blast furnace water-quenched slag 500mm, the particle size is 0.5 ~ 1.0mm. The upper filter material is blast furnace heavy slag, which is used to intercept the suspended solids with large particle size in water, and ...

Abstract

The invention provides a method of disposing the sewage by use of the metallurgic filter material, which is metallurgic dual-filter material consisting of water quenching residue and metallurgic dry slag. The filter material is filled into a filtering tower (pool) for disposing sewage. The invention has the advantages of low cost, obvious disposing effect and multiple functions of comprehensively disposing sewage; besides, the removal rates of the suspended solid, the organic and the ammonia nitrogen in the sewage are respectively 60 percent to 86 percent, 40 percent to 70 percent, and 70 percent to over 90 percent, the water quality of yielding water is stable.

Description

1. Technical field: [0001] The invention relates to a sewage treatment method, and also relates to a treatment method of solid waste metallurgical slag. 2. Background technology: [0002] Sewage contains a large amount of suspended solids, organic matter, and ammonia nitrogen. If not treated, it will cause serious harm to the environment. Especially urban comprehensive sewage and industrial sewage need more treatment. Most of the existing treatment methods are chemical flocculation to treat suspended solids, flocculation and sedimentation to treat organic matter, and ion exchange resin to treat ammonia nitrogen. These methods have the characteristics of large investment, incomplete treatment, and high cost. Therefore, it is necessary to seek a low-cost, multi-functional new material and new method. 3. Contents of the invention: [0003] The object of the present invention is to provide a low-cost, multifunctional metallurgical slag filter material method for treating se...
