Circulating water side filtration treatment system

A Coking Plant Chemical Three Circulating Water Side Filtration Process

Abstract

A coking plant chemical three circulating water side filtration process (treatment capacity 400 m/h filter diameter 2.8 meters)

Project Background

A coking plant chemical three circulating water side filtration process (treatment capacity 400 m/h filter diameter 2.8 meters)

To achieve the effect

1. Ultra-high filtration rate, running flow rate 60-80 m/h,(traditional filter 8-12 m/h and 20-40 m/h)

2. After two months of operation, the average turbidity of the circulating water system dropped from 25.4 NTU to 2.5 NTU, and the fluctuation range was 0.3-5NTU. The turbidity of the filter effluent was below 1NTU, accounting for 30%

3. clean with raw water, backwashing water only needs <0.4, 30-40m/time. God,

4. The backwash water shall be treated nearby without adding any chemicals. The underflow shall be discharged once every 3-7 days. The outer drainage amount shall be 0.1-0.2 ‰, and the underflow drainage shall be less than 2m per day. (There is no drainage condition on site and existing supporting treatment process)

Treatment of Wet Flue Gas Desulfurization Wastewater from Coal-fired Power Plants and Various Self-owned Power Plants

The desulfurization wastewater treatment unit of the second phase of the original 1. of a power plant in Tianjin adopts the traditional process of "triple box clarifier". The failure rate of the system equipment is high, and the fluctuation of the effluent water quality brings great pressure to the operation adjustment and equipment maintenance of the zero discharge system of desulfurization wastewater. The operation rate of the zero discharge system of desulfurization wastewater is low.

Petrochemical coal-fired unit flue gas wet desulfurization wastewater treatment

The original electrolytic aluminum flue gas desulfurization system is not equipped with desulfurization wastewater treatment system. The desulfurization wastewater is discharged into the sewage treatment system of the whole plant after comprehensive treatment. Due to the high content of suspended solids and TDS in the desulfurization wastewater, the original sewage treatment system of the whole plant has a great impact.

Iron and steel smelting sintering pellet flue gas wet desulfurization wastewater treatment

The desulfurization system of the original sintering plant is not equipped with desulfurization wastewater treatment system, and the desulfurization wastewater is discharged into the sewage treatment system of the whole plant after comprehensive treatment. Due to the high content of suspended solids, high TDS content and serious excessive heavy metals, the original sewage treatment system of the whole plant has a great impact.
