Water pollution treatment and separation system

Abstract

The invention discloses a water pollution treatment and separation system which mainly comprises a reaction tank, a concatemer precipitator and a filtering clear water tank sequentially connected in series. A plurality of partition plates which are arranged in an up-down staggered mode are arranged in the reaction tank to prolong a water flow path, and the concatemer precipitator comprises a transversely-arranged overflowing pipeline and a plurality of vertically-arranged sludge precipitation pipes. The overflowing pipeline is connected between the reaction tank and the filtering clear water tank, the sludge precipitation pipe is connected below the overflowing pipeline, a blow-down valve is arranged at the lower end of the sludge precipitation pipe, a filtering plate is arranged in the filtering clear water tank, and a water outlet is formed in the filtering clear water tank. Static water flow is formed in an overflow filling mode, flocs are precipitated, captured and collected in the process, the flocs can be effectively separated, the filtering plate efficiently captures the flocs, blockage is avoided, long-time continuous work can be achieved, and the system is more economical and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a separation system for water pollution control. Background technique [0002] When water treatment uses chemical methods to separate dirt and impurities, it is necessary to coagulate drugs and impurities to produce flocs, and then the flocs are driven by the fine floating bubbles in the water-soluble air to float on the water surface, and then the water surface is removed by a mechanical mud scraper. The floc sludge on the scraper is scraped away, so as to achieve a certain degree of mud-water separation. However, due to the accumulation of floating flocs, the weight increases and the micro-bubbles disappear. Under the mechanical action of the mud scraper, it is easy to settle and pollute the clear water in the lower layer, and the separation in the true sense cannot be achieved. How to collect the sediment Large-particle flocs, and then capture the suspende...

Problems solved by technology

However, due to the accumulation of floating flocs, the weight increases and the micro-bubbles disappear. Under the mechanical action of the mud scraper, it is easy to settle and pollute the clear water in the lower layer, and the separation in the true sense cannot be achieved. How to collect the sediment Large-particle flocs, and then capture the suspended tiny flocs, is the key factor for the thoroughness of water pollution treatment; in addition, the traditional cotton filter used to capture suspended flocs is easy to form a water film, not only often clogged, but also a waste of consumables , need frequent replacement and maintenance, it is easy to cause secondary pollution, the cost is high, and water pollution cannot be treated efficiently
