Problems solved by technology

The equipment (pool) is large
[0006] 2. Slurry treatment and equipment are separated, and the project covers a large area
[0007] 3. The packing filter is easy to block, and the cleaning system is complicated and not thorough
[0008] 4. Poor effect on softening and desalination of medium and low hardness water
[0009] 5. The pipeline system of lime softening reaction equipment is prone to fouling and blockage, complicated cleaning and large maintenance
[0010] 6. Lime dust and discharged slurry will pollute the environment
[0011] 7. Most of the equipment (pool) is a single function or a simple combination

Embodiment Construction

[0054] Referring to Fig. 1 and Fig. 2, the purchased liquid negative pressure generator 1 communicates with the raw water inlet pipe 2 and the raw water delivery pipe 3 respectively. The equivalent dry powder dosing device 4 includes a water-medicine mixing chamber 7 that is connected with the raw water delivery pipe 3 and contains an unpressurized water inlet 5 and a medicament outlet 6 as shown in Figure 2. Conveyor 9. There is a control valve 10 at the front end of the water-medicine mixing chamber. There is a DC variable speed motor 12 in the dry powder dispenser housing 11 communicated with the medicament inlet, and a tapered screw conveyor 13 with blades at the medicament outlet that is connected to the DC variable speed motor. The housing of the dry powder dispenser communicates with the liquid negative pressure generator and the purchased gas negative pressure generator 16 through the dry powder medicament delivery pipes 14 and 15 respectively. A dry powder medicamen...

Abstract

An aqualizing / unequalizing water-treating process includes such steps as equalization reaction between lime powder and raw water for softening it and removing salts, then tangentially flowing in a cyclone coagulating chember where lime powder is added to generate a lot of the active flocculates of multi-nuclear hydroxy calcium, generating big coagulations, deposition separation of water from coagulation, classifying water to obtain clean water, concentrating and separating the coagulations and dewatering. Its treating apparatus is also disclosed.

Description

Technical field: [0001] The invention relates to the field of water treatment, in particular to a high-efficiency treatment process and equipment for softening and clarifying single lime. Background technique: [0002] The existing lime softening water treatment process mostly adopts the method of softening and coagulation. The coagulant generally adopts polyferric sulfate, ferrous sulfate, ferric chloride, or polyaluminum chloride. The settled slurry cannot Recycling; or adopt the method of natural sedimentation and filtration. [0003] The existing clarification and purification reaction equipment is mainly divided into two categories: one is hydraulic and the other is mechanical. The former includes: clapboard reaction pool, swirl flow reaction pool. Vortex reaction, folded plate reaction tank, chamber swirl reaction tank, self-excited reaction clarifier, etc., are characterized by simple equipment, low investment, low operating cost, high chemical consumption, and narr...
