Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the defects of the existing high-suspension and easy-to-biochemical wastewater treatment, the wastewater treatment system cannot run stably, and the treated wastewater cannot meet the standard discharge, etc., and provides a method that can effectively treat pollutants and achieve compliance. At the same time, it can save investment, save land, operate stably without being affected by seasonal temperature, and a new type of wastewater treatment method with low operating costs

Embodiment Construction

[0031] The present invention will be further explained below in conjunction with the drawings;

[0032] Such as figure 1 The shown method for treating highly suspended solids easily biochemical wastewater includes the following steps:

[0033] (1) Waste water is filtered through the coarse and fine grids, flows into the collection and adjustment tank, and is transported by the sludge pump to the dissolved air flotation for deep solid-liquid separation. The waste water is flocculated and stirred by adding iron salt through the automatic dosing device before entering the air flotation. In order to ensure the effect of air flotation separation and the purpose of phosphorus removal, the solids separated by dissolved air flotation can be directly composted and fermented, and the separated wastewater enters the next step through the pipeline.

[0034] (2) The separated wastewater enters the anaerobic and facultative reaction tank. The design scale of the anaerobic reaction tank is HRT=48h...

Abstract

The invention discloses a high-suspension easy-to-biochemically treated wastewater treatment method, which is applied to the treatment of various kinds of high-concentration easy-to-biochemically treated organic wastewater. The method comprises the following steps of 1, collecting wastewater, and performing advanced solid-liquid separation in a dissolved air flotation way; 2, performing anaerobic decomposition on the separated wastewater by using anaerobic and facultative tanks; 3, causing the decomposed wastewater to enter an MBR (membrane biological reactor) process system; and 4, disinfecting and sterilizing effluent obtained by an MBR process to discharge water reaching standards by using sodium hypochlorite. According to the wastewater treatment method, high-concentration easy-to-biochemically treated wastewater can be effectively treated, the construction fund can be greatly saved, a small land is occupied, and the method is stable in running, low in cost and particularly suitable for industrial production.

Description

Technical field [0001] The invention relates to a method for processing high-concentration easily biochemical wastewater, in particular to a method for processing slaughter wastewater, livestock and poultry breeding wastewater, food processing wastewater and urban domestic sewage. Background technique [0002] my country is a country with severe drought and water shortage. The total amount of fresh water resources is 2.8 trillion cubic meters, accounting for 6% of global water resources. It is second only to Brazil, Russia and Canada, ranking fourth in the world, but only 2,300 cubic meters per capita. It is only 1 / 4 of the world average and ranks 121 in the world. It is one of the 13 countries with the poorest water resources per capita in the world. [0003] After the 1950s, the global population grew rapidly, and industry developed rapidly. The global water resources situation is rapidly deteriorating, and the "water crisis" is getting worse. On the one hand, human demand for ...
