Efficient sewage treating equipment

Abstract

The invention relates to equipment of a sewage treating system, specifically to efficient sewage treating equipment. The efficient sewage treating equipment comprises a sewage inlet pipe which is communicated with a sewage source, a sewage pump for pumping out sewage, a regulating basin for storing sewage, a biological revolving cage reactor for purifying the sewage, a secondary precipitating basin, a dosing tank which is communicated with the secondary precipitating basin and a sewage dehydrating basin which is communicated with the secondary precipitating basin, wherein sampling cans are respectively arranged in the regulating basin and the secondary precipitating basin; one of the sampling cans is fixed on the bottom of the regulating basin, and comprises a can body, an enclosing blockand a refrigerating system; an opening is formed in the upper end of the can body; a liquid inlet gap is formed in the side wall of the can body, and extends from the top of the can body to the bottomof the can body; the enclosing block can enclose the liquid inlet gap; a communicating hole is formed in a contact position of the regulating basin and the sampling can; a sampling pond is communicated to the lower part of the communicating hole; a buffer solution is placed in the sampling pond; a cutting knife is arranged on one side of the communicating hole. The invention provides the sewage treating equipment which can treat sewage effectively, and can quickly and accurately perform water quality sampling.

Description

technical field [0001] The invention relates to equipment of a sewage treatment system, in particular to high-efficiency sewage treatment equipment. Background technique [0002] At present, the advanced technologies for sewage treatment at home and abroad mainly include biological methods, chemical methods and physical methods. In the treatment of a large amount of industrial sewage or urban sewage, the biological method is the most adopted method. The principle of the biological method is to use microorganisms to decompose organic matter, and supplement the oxygen required for microbial respiration and decomposition of organic matter through mechanical oxygenation. [0003] In the prior art, a biological tumbler is used to purify sewage. The biological tumbler is equipped with biological fillers, and the microorganisms on the biofilm on the surface of the biological fillers have the effect of treating pollutants in the sewage. The inventor designed a sewage treatment sys...

Problems solved by technology

[0004] The problem with the above method is that due to the uncertain time from sampling storage to random inspection, there are many microorganisms in the sewage, and when the sewage is treated by biological methods, there are more microorganisms in the sewage that can affect the test results. Microorganisms will change the water quality, resulting in inaccurate sampling and testing
