Abstract

A comprehensive treatment method of high-concentration organic wastewater comprises primary treatment and secondary treatment. The method is characterized in that a high-efficiency solid-phase object blocking device is adopted in the primary treatment, and the secondary treatment is to combine a physicochemical treatment technology (SUN-SEP for short) of chemical coagulation and hydroxyl radical oxidation with a multi-flora sludge-free biological treatment sewage technology (BMS for short). The treatment process of the high-concentration organic wastewater comprises the following steps: the high-concentration organic wastewater firstly enters a high-efficiency solid-phase object blocking device, enters a SUN-SEP stage after being intercepted, and finally is treated by a BMS to be discharged. The system has no excess sludge treatment device, and solves the problems of foreign odor in the traditional treatment method, sludge blockage in the biological treatment process and the need of excess sludge treatment. Can be used for treating high-concentration organic wastewater containing high suspended matter concentration.

Claims

Claim

1st, a kind of integrated conduct method of high concentrated organic wastewater, including coagulation and two stage treatment, it is characterised in that coagulation is blocked to carry and put using efficient solid formation, two stage treatment is the materializing strategy technology by coagulation plus hydroxy radical oxidation（Abbreviation SUN-SEP) with many floras without sludge organism handle Technology of Sewage（Abbreviation BMS) it is combined, the handling process of high concentrated organic wastewater is：High concentrated organic wastewater, which initially enters efficient solid formation and blocks to carry, to be put, and enters the SUN-SEP stages after interception impurity, finally by BMS handle after water outlet.

2nd, integrated conduct method according to claim 1, it is characterized in that described efficient solid formation, which blocks to carry, is set to gravity continuous conveyor filter, high concentrated organic wastewater first passes around gravity continuous conveyor filter, suspension and floating object and partial suspended thing containing a large amount of larger particles are trapped in high concentrated organic wastewater, trapped substance enters solid formation collecting pit after being collected through solid formation automatic collecting device, waste water enters after damming through filtering

BMS regulating reservoirs pond.

3rd, integrated conduct method according to claim 1, it is characterised in that described SUN-SEP process steps are：The pond water outlet of BMS regulating reservoirs is lifted into SUN-SEP wastewater treatment equipments with pump, pass through the chemical oxidation reaction process of coagulation air-float, OH- hydroxy radicals, polluter is removed, and the solid formation scum silica frost that air supporting is produced enters solid formation collecting pit after being collected through automatic scraping slag system.

4th, integrated conduct method according to claim 1, it is characterised in that SUN-SEP water outlets sequentially enter filling material and efficiently micro- aeration tube in four lattice point ponds of BMS bio-oxidation ponds, pond,

Process step is：
